Task 1: Data Acquisition and Processing 
1. Introduction
It is well known and documented that changes in water quantity, timing and quality are 
introducing negative impacts to the Everglades ecosystem (Richardson et al., 1990; 
Walker, 1991 and 1995; Davis et al., 1994; Ligth and Dineen, 1994; McCormick et al., 
1996; USFWS, 2000; Brandt et al., 2000; Raghunathan et al., 2001; Childers et al., 2003). 
Historically, the Kissimmee River discharged into Lake Okeechobee, and during wet 
cycles the lake would overflow its south bank, providing additional flow to the 
Everglades (Ligth and Dineen, 1994). Water, which once flowed in a broad swath across 
the Everglades, is now concentrated through canals, structures, and a series of water 
storage areas (Water Conservation Areas (WCA)). That water, when not used for 
municipal water supply or irrigation, is discharged to the Everglades National Park 
(ENP). 
According to the Comprehensive Conservation Plan for the Refuge (USFWS, 2000) the 
construction of the levees has had significant effects on the hydrology, vegetation and 
wildlife in the refuge. The U.S. Fish and Wildlife Service (USFWS, 2000) indicated 
that changes in natural timing of water levels affect wading birds feeding patterns, apple 
snail reproductive output, and alligator nesting. Similarly, changes in the spatial 
distribution of water levels alter the distribution of aquatic vegetation and tree islands. In 
addition, and particularly during the dry season, lower water levels increase the potential 
for fire and damage to vegetation, soils and wildlife. The USFWS in partnership with the 
South Florida Water Management District (SFWMD) and the U.S. Corps of Engineers 
are devoting considerable resources to restore and maintain appropriate water regimes for 
the Refuge. 
Along with the changes in water quantity and timing, the changes in water quality are an 
important threat to the Everglades ecosystem. High concentrations of nutrients 
(specifically phosphorus) in runoff from agricultural areas cause proliferation of cattails, 
and other undesirable species that negatively affect the ecosystems balance. Other 
negative impacts from increased nutrients include: increased soil phosphorus content, 
changed periphyton communities, loss of native sawgrass communities, increased organic 
matter in water, reduced dissolved oxygen, conversion of wet prairie plant communities 
to cattail, and loss of important habitats for wading birds (Stober et al., 1996). 
Along with ensuring an appropriate water regulation schedule, it is a priority for the 
Refuge to better understand and minimize the impacts of these excessive nutrient 
loadings. The purpose of the planned Refuge hydrodynamic and water quality modeling 
is to provide a quantitative framework for management decisions related to Refuge 
inflow and outflow quantity, timing, and quality. This modeling effort will provide 
projections of water movement and water quality resulting under alternative scenarios of 
structure operation, Storm Treatment Area (STA) performance, and structural changes 
within the Refuge. When fully calibrated and validated, the selected model should 

provide information and assist in answering questions on the hydrologic, hydrodynamic, 
water quality, and ecologic processes occurring under present conditions and 
management rules; and how these processes would be altered by different structural 
changes and management scenarios. For example: How different management scenarios 
(structural alterations, management decisions, strategies, and regulations) alter: 
o The hydrology. How will the spatial and temporal distribution of water 
inside the Refuge be altered? Will portions dry out and for how long? Is 
significant surface-groundwater interaction in the Refuge occurring? If so, 
what are the effects? 
o The hydrodynamics. How will near field hydrodynamics close to 
hydraulic structures be altered? How will far field current patterns be 
altered? 
o Water quality. How will water quality be altered? How will the spatial 
and temporal distribution of phosphorous inside the Refuge be altered? 
o The ecosystem. How will the ecosystem be affected by changes in 
hydrology? Will local changes in hydroperiod sustain the needs of desired 
plants and wildlife? 
It should be emphasized that the numerical model that will be developed is not a regional 
model. Therefore, it will not project the response of the natural system outside the 
Refuges boundaries to any alternations. It will however, provide detailed information 
about the response of the Refuge to regional management changes and alterations. 
This report focuses on data acquisition and processing, starting with the selection of the 
water quality constituents to be modeled and the selection of periods of records for 
calibration and validation. It assesses whether sufficient data is available to achieve the 
modeling goals. It also provides recommendation for monitoring where additional data is 
needed. The description of the Refuges background, hydrology, soils, physiographic, 
water management and regulation, as well as a comprehensive literature review of 
previous modeling efforts within the Refuge and wetland systems, will be presented in 
companion reports. 
1.1 Objectives
As indicated in the previous paragraph the main goals of this report are: 
 Identify the period of record for calibration and validation of the numerical 
model. 
 Identify the constituents to be modeled. 
 Compile the data needed to support the modeling effort. 
 Check the quality and resolution of the gathered data. 
 Determine if sufficient data is available to achieve the modeling goals. 

2. Constituents to Be Modeled 
Since the everglades are oligotrophic-phosphorus limited systems (Childers et al., 2003; 
McCormick et al., 1996; Raghunathan et al., 2001; SFWMD, 2000), the discharge of 
excess amount of this nutrient will promote the eutrophication process and ecosystem 
imbalance, e.g., shifts in plant community composition. The 2000 Everglades 
Consolidated Report (2000 ECR) by the SFWMD indicated that the ratio of total nitrogen 
to total phosphorus (TN:TP) in the Refuge, increased from near 50:1 in the canal to near 
150:1 in the marsh interior. Since values of TN:TP higher than 8:1 suggests phosphorus 
(P) limitation, the ratios for the Refuge are a clear indication that: (1) P is the more 
important limiting nutrient in both the marsh and canal waters; and (2) the severity of P 
limitation increases with increasing distance from the canal. The USFWS (2000) 
indicated that areas in the western, southwestern, southern and southeastern portions of 
the Refuge continue to be eutrophied by the influx of high nutrients runoff (specifically 
phosphorus) from agricultural lands. The hydrodynamic and water quality models being 
developed will be of value in testing this conjecture. 
According to Childers et al. (2003) water column total phosphorus concentrations in the 
Everglades are typically less than 10 mg/L. It is well documented that water flowing into 
the Everglades has an anthropogenic load of nutrients and other contaminants (e.g., 
Richardson et al., 1990, Stober et al., 1996; USFWS, 2000). Nutrient loading from urban 
areas and the Everglades Agricultural Area (EAA) has significantly increased nutrient 
concentrations, particularly phosphorus, in the water conservation areas (USFWS, 2000). 
Childers et al. (2003) reported that in northern Everglades regions, near to the EAA, total 
phosphorus concentrations often exceed 100 mg/L. Therefore, it is a priority for the 
Refuge to better understand the dynamics of nutrients on the systems, particularly of 
phosphorus, in order to minimize the impacts of this excessive nutrients loading. Total 
phosphorus in the sediments and in the water column is going to be modeled as a 
constituent in order to address this objective. 
It is important to accurately describe the hydrodynamic processes in order to determine 
and evaluate water quality impacts on wetlands (Mitsch, 1988; Mitsch and Reeder, 1991; 
Moustafa and Hamrick, 2000). The accurate description of the hydrodynamic often 
requires fine-tuning of certain model parameters, i.e., calibration, to match observed and 
predicted values, e.g., water surface elevations, water depths, water velocities, 
constituents concentrations, etc. After calibration, a validation process is usually 
conducted to ensure the model accuracy. However, the validation of velocities and 
transport subroutines are often not completed primarily due to lack of field 
measurements. 
To the best of the authors knowledge, there are no velocity measurements anywhere in 
the Loxahatchee Refuge. Therefore, a recommendation will be made to Refuge personnel 
to collect surface flow velocities in the rim canal as well as at interior sites. Although, the 
ability to model advection and diffusion can be assessed through modeling of 
conservative constituents, if deviation from the field measurements is observed, it would 
not be possible to determine whether the deviation is caused by error in the models 

advection or by the diffusion terms. It is believed that even a short term measurement of 
velocities at multiple locations within the Refuge will be of great value to this modeling 
effort. 
Traditionally, conductivity, total dissolved solids (TDS) and chloride have been used as 
conservative or semi-conservative tracers. Conductivity and TDS are highly correlated, 
and even though they are not fully conservative parameters, they can be used as such 
when high concentrations are present in the influent runoff/wastewater, assuming that 
wetlands have a negligible effect on these parameters. Kadlec and Knight (1996) 
indicated that wetlands have minimal effect on TDS. This is especially true because TDS 
concentrations are usually high in wastewaters and the individual components of these 
solids greatly exceed the biological requirements for growth. Kadlec and Knight (1996) 
recommended the use of chloride content as a tracer in wetland systems. They indicated 
that due to low biological demand, its abundance in surface water and its high solubility, 
the total mass of chlorine remains relatively constant in wetland systems. Based on this 
recommendation, the initial approach in this modeling effort will be to use chloride as 
tracer to evaluate the model transport subroutine. 
3. Period of Record 
Some of the processes and transformations that occur in wetland systems sometimes take 
years. An example of a long term process is the shift in plant community composition 
that may occur after the accumulation and/or release of phosphorus in the soil. These 
factors underline the need to perform long-term simulations. 
An ideal period-of-record (POR) covers a large number of years with periods of extreme 
meteorological and hydrological conditions that adequately calibrate and test the model 
performance. It is also of value to have a POR that includes major structural changes (e.g. 
diversion of S-6 pump, STA-1E operation) because this further tests the models ability to 
project such changes. It is desirable to select a POR ending as close as practical to the 
present. The POR for model calibration and possible verification should consider data 
availability, and quality. This task will require a preliminary review of data from various 
sources. Accordingly, a tentative POR is selected to be 1995  2004. This period will be 
further divided into two segments where one will be used for model calibration, and the 
other for validation. This report summarizes the types of data that have been collected for 
the POR, identifying any missing periods and indicating the apparent quality of such 
data. 
4. Types of Data 
The field measurements needed to support this modeling effort include bathymetric, 
meteorological, hydrologic, and water quality data. Many of these datasets are spatially 
variable (e.g., elevation), and some are both temporally and spatially variable such as all 
meteorological, hydrologic, and water quality parameters. Data sources will be identified 

for all data types required. The types of data that have been compiled and are discussed 
in this report are: 
 Bathymetric data 
 Hydrologic data: water level and discharges through hydraulic structures 
 Meteorological data: rainfall, temperature, evapotranspiration (ET), and wind 
 Water quality data: concentrations of the parameters of interest at available 
sampling sites. 
5. Procurement and Quality Assurance of Bathymetric Data 
5.1 Marsh Elevation Data
Bathymetric surveys for the Loxahatchee Refuge have been available from different 
sources and with different resolution. Lin and Gregg (1988) indicated that, in 1988, 
topographic maps of the Refuge were available from three different sources: (1) the U.S. 
Army Corps of Engineers (1958), (2) the Fish and Wildlife Service, Department of 
Interior (1963 and 1965), and (3) the South Florida Water Management District (1965). 
Lin and Gregg (1988) reported that, in some areas, there were considerable differences 
between the three sources. A later survey of the Refuge was conducted by Richardson et 
al. (1990) who collected topographic and vegetation cover data, as part of their study of 
refuge habitats and relationship to water quality, quantity and hydroperiod. The 
topographic data was collected at a resolution of approximately 1 minute (roughly 2 Km) 
by measuring the water depth at all grid locations and then subtracting from an assumed 
horizontal water level. A flat pool condition of water in the Refuge was obtained by 
holding water at the 17-foot level during the time that the grid survey was being 
conducted. 
The latest elevation data for the Refuge are available from the United State Geological 
Survey (USGS). The elevation data were collected as bare earth ground elevation on a 
400 by 400 meter grid. "Bare earth" in the Everglades swamp environment is considered 
to be the layer of "muck" which supports a one-pound weight on a bearing surface of 
approximately 5.3 square inches or 2.6-inch circle. According to Desmond (2003) the 
horizontal positions were established by GPS observations and are referenced to the 
North American Datum of 1983 (NAD83). The horizontal accuracy is +/- 15 centimeters. 
Similarly, the elevation data have a vertical accuracy specification of +/-15 centimeters 
(cm) relative to the North American Vertical Datum of 1988 (NAVD88). Desmond 
(2003) indicated that the vertical accuracy of the elevation data was determined based on 
the requirements for use as input to hydrologic models. More information about this 
elevation data is available at the USGSs South Florida Information Access (SOFIA) 
website (http://sofia.usgs.gov/projects/elev_data/). Since the water level data from the 
Refuge interior stations and from the water management structures are based on the 
National Geodetic Vertical Datum (NGVD29), the USGSs bathymetric data were 
converted from the NAVD88 to the NGVD29 system using the National Geodetic Survey 

software VERTCON Version 2.1. Figure 1 shows the bathymetric contours for the 
Loxahatchee Refuge based on the USGSs data. 
Results of this survey indicate that, in the Refuge, the bathymetry contours (excluding the 
rim channel) range from 18.50 to 10.61 ft (5.64 to 3.23 m) NGVD29, with a mean 
elevation of about 15.17 ft (4.62 m) NGVD29. 
Figure 1. Loxahatchee Refuge 2003 USGS Bathymetric Data 
As can be observed in the profile presented in Figure 2, the Refuge has a very mild north 
to south slope, which results in a generally slow southward flow movement. Lin (1979) 
indicated that flow through the heavily vegetated area in the Refuge is extremely slow as 
compared to the flow in canals. The north to south slope is estimated to be about 1.6 cm 
in 1 Km (1.0 inches per mile). In the west to east direction (see Figure 3), the terrain is 
undulated showing mounds and depressions, but with basically an average horizontal 
slope.

5.2 Rim Canal Cross-Section Data 
The rim canal bathymetric data were collected by the University of Floridas Institute of 
Food and Agricultural Sciences (IFAS), specifically by the Everglades Research and 
Education Center. This survey of the rim canal was performed in 2001 by Daroub et al. 
(2002) as part of the project: Implementation and Verification of Best Management 
Practices for Reducing Loading in the Everglades Agricultural Area (EAA). The survey 
was conducted by measuring sediment depth and channel bottom depth with reference to 
the transects surface water level at the time of the measurement. The water depths were 
later converted to elevations using the mean tail-water elevation of station G-310 
(referenced to NGVD29) that prevailed on the day of measurement. It was assumed that 
there was no hydraulic gradient between G-310 and the transects at the time of 
measurement. Sediment samples and cross section elevations were taken approximately 
at one-mile resolution. The transect locations of the survey are shown in Figure 4. 
Figure 4. Rim Canal Transects (IFAS Survey) 
Twenty eight transects were taken for each canal system, i.e., the western system that is 
formed by the L-7 and L-39 canals and the eastern system that is formed by the L-40 

canal. The distance between transects ranges between 1.15 and 0.90 miles for the 
western system and between 1.03 and 0.92 miles for the L-40 canal, being the average 
distance equal to 1.0 mile for both systems. As indicated before, sediment surface levels 
and channel bottom levels were measured, and were standardized with the G-310 tailwater 
elevation as reference level. The G-310 tail-water level is based on the National 
Geodetic Vertical Datum (NGVD29). Figure 5 shows the cross section elevations for the 
L40-01 transect.

elevations range between 6.7 and -5.7 ft NGVD29 with a mean elevation equal to 3.2 ft. 
The top width ranges between 205 and 120 ft for the western canal, and between 173 and

The thalweg profiles for the sediment surface elevations and for the channel bottom 
elevations are presented in Figures 6 and 7, for the L-7/L39 canals and for the L-40 canal, 
respectively. The profiles for the L/7/L-39 canals are quite irregular with almost a 
horizontal average slope. Channel aggradation seems to have occurred in the L-7 canal as 
results of an adverse slope in the channel bed; for this canal the sediment depths vary 
between 10.2 and 2.5 ft with an average depth of approximately 5.5 ft. It is important to 
note two other major features in these profiles: a thalweg drop of more than 4 ft between 
canal miles 15 and 16, close to the confluence of the L-7 and L-39 canals; and a steep 
adverse slope with great accumulation of sediments between canal miles 21 and 23 in the 
L-39 canal. On the other hand, the profile for the L-40 canal is better defined with a north 
to south mild slope of about 3.2 inches per mile, see Figure 7. The sediment depths for 
the L-40 canal range between 6.6 and 0.9 ft with and average depth equal to 3.0 ft. 
Another interesting observation to the canal data is the difference of more than 8 ft on 

sediment elevations for the downstream ends of L-39 and L-40 canals, when these points 
are only about 1.7 miles apart.

6.1 Interior Station Stages 
The water levels in the Loxahatchee Refuge change due to drought, rainfall, 
evapotranspiration, seepage, and surface water management based on regulation 
schedules that vary with the time of the year, hydrologic, and other needs (SFWMD, 
2005). According to the USFWS (2000) the purpose of these schedules is to regulate the 
water level in WCA-1 to produce maximum benefits for flood control, water supply, fish 
and wildlife, and prevention of salt water intrusion. A schematic diagram of the current 
water regulation schedule (established in May 2005) is shown in Figure 8.

Spatial water level information inside the Refuge is scarce. Actually there are only five 
active stations inside the Refuge, two of them in operation just after mid 2001. These five 
stations are referred as 1-7, 1-9, 1-8T, North and South. The location of USGSs water 
level monitoring stations is shown in Figure 9. Historic daily average water level data 
from 1954 to 2005 are available at USGS sites 1-7, 1-9, and 1-8C, although the site 1-8C 
is located in the rim canal. The stage-monitoring site 1-8T has water level measurements 
since 1979. Water level data from recently installed USGS sites North and South are 
available only after June, 2001. The water level data can be obtained at the SFWMDs 

Environmental Data Base (DBHYDRO) website (www.sfwmd.gov/org/ema/dbhydro/). 
Table 3 shows the available and missing data for each of these stations for the POR. A 
more detailed description of the interior stage missing data is presented in Appendix G.1.

Note: In this Table and in the rest of the document the data reported yearly correspond to 
a calendar year (if it is not otherwise indicated). 

The DBHYDRO database usually presents more than one time series available for each 
gage. For the selected POR (1995 to 2004), there are between 3 and 5 different time 
series available for each of the sites 1-7, 1-8T, 1-8C and 1-9. Most of these time series 
data sets have overlapping time periods. There is no explanation at the website about this 
issue, however, the DBHYDRO browser user documentation manual recommends that 
whenever "PREF" data are available for a date record of interest it should be used to 
exclusion of all other data since such data sets already underwent a second level of 
quality assurance and quality control (QA/QC) by engineers in Environmental 
Monitoring and Assessment Division (SFWMD, 2003). Since not all the stations include 
a PREF file or the PREF file does not always cover the complete period of interest, 
all the time series available were retrieved from the DBHYDRO website and compared 
against each other. Appendix A1, Figures A1.1 to A1.22, shows the time series available 
for each gage and also the comparisons between them. Table 4 shows the names of the 
time series available for each gage, and also the time series that were selected to be used 
during the Refuge modeling effort. This table also indicates the arithmetic means of daily 
average water levels for the POR, and the maximum and minimum daily average stages 
reported during such period. The major observations to the time series, as well as any 
modification to the data, are also reported in Table 4. 
For the POR, the arithmetic means of daily average water levels for the interior stations 
(1-7, 1-8T, and 1-9) range between 16.55 and 16.26 ft NGVD29, and the maximum and 
minimum daily average stages are 18.12 and 13.94 ft NGVD29, respectively. For gage 18C 
(located in the rim canal) the arithmetic mean of daily average water level is 16.31 ft 
NGVD29, and the maximum and minimum daily average stages are 18.19 and 12.06 ft 
NGVD29, respectively. Gage North presents a higher average stage (16.73 ft NGVD29) 
than the rest of the stations, and gages South has a lower average stage (16.10 ft 
NGVD29), but these stations only have data for the period from May 2001 to December 
2004.

6.2 Head and Tail Water Levels from Hydraulic Structures 
Head-water and tail-water stage data, for the hydraulic structures associated with the 
Refuge, are also available from the DBHYDRO website. These data are essential for 
documenting the spatial and temporal stage variations along the rim canal. The water 
level data for the hydraulic structures were divided into four groups according to the 
structure location: a) the northern stations, this group includes structures S-5A, S-5AS, 
G-301 and G-300; b) the western stations, this group includes structures G-310, G-251, 
S-6, S-10E and G-338; c) the southern stations, structures S-10D, S-10C, S-10A and S-39 
are included in this group; and d) the eastern stations, structures S-362, ACME-1, 
ACME-2 or G-94D, G-94C, G-94B and G-94A are included in this group. Figure 10 
shows the location of the hydraulic structures associated with the Refuge. 
Figure 10. Location of Hydraulic Structures in the Loxahatchee Refuge 
Table 5 shows the available head- and tail-water level data for the nineteen hydraulic 
structures around the Refuge. As can be observed in the table, not all the structures were 
in operation from the start date of the POR. For example, structures G-301 and G-300 
started operating in August 1999 (Waldon, 2005). Structure G-310 started operating on 

July 2000 (Waldon, 2005). On the other hand, the structures located at the eastern part of 
the Refuge (ACME-1, G-94D, G-94C, G-94B and G-94A) were in operation for the 
complete POR. For these stations, the time series available at the DBHYDRO website are 
missing between 57 and 89 months with respect to their head and tail water levels, while 
some stations do not have head water levels available (see Table 5). The investigators are 
continuing to search for the missing data. 
Head and Tail water level data for the stations S-10D, S-10C and S10-A is also available 
at the USGS website (http://water.usgs.gov/data.html). A more detailed description of the head 
and tail water level missing data is presented in Appendix G.2.

As in the case of the interior stations, the DBHYDRO database sometimes shows more 
than one time series available for the same station (see Tables 6 to 9); unfortunately, for 
the head/tail water levels there were not PREF files available. The time series available 
for each station, as well as the comparison among them, are included in Appendix A2, 
Figures A2.1 to A2.66. Data for the S-362 station is only available after 10/14/2004, and 
therefore the head and tail water levels time series for this station were not included in the 
appendices. Tables 6 to 9 summarize the major observations to the head and tail water 
level data, and also indicate the time series recommended to be used for the modeling 
effort. If not otherwise indicated, the data in the time series shown in Tables 6 to 9 and 
Appendix A2 are daily mean values. 
As seen in Tables 6 to 9, the arithmetic means of daily average water levels inside the 
Refuge range from 16.28 to 15.93 ft NGVD29 for the 17 hydraulic structures, and for the 
POR. Similarly, the maximum and minimum daily average stages are 18.98 and 11.54 ft 
NGVD29, respectively. It is observed that for the POR the water level for the structures 
along the rim canal, on average, is lower than that of the interior stations. However, the 
maximum daily average stage reported for the structures (i.e., 18.98 ft) is higher than the 
maximum value reported for the interior stations (i.e., 18.12 ft). This information shows 
that, on average, the water level in the channel is lower than the water level of the marsh. 
However, under certain conditions the water may overflow the rim canal and moves as 
sheet flow toward the interior of the Refuge. According to Waldon (2005) at high stages 
there is typically little difference between stage in the marsh and at non-operating 
structures and pumps. When outflow gates are opened, stages at the structure headwaters 
fall below the stage representative of the broader region of the canal in the vicinity of the 
structure. At lowest canal stage, water surface elevation falls below interior marsh soil 
elevation and monitored marsh stages. 
Note in Tables 4 to 9 and for the rest of this document, the term extreme event has been 
used arbitrarily to indicate a period of time when a particular parameter, e.g., water level, 
shows an unusual high or low value when compared to other high/low values and/or to 
the arithmetic or geometric mean of the data. The classification of a period of time as an 
extreme event is partially subjective, and has no other purpose than to illustrate such 
particularity of the data.

7. Procurement and Quality Assurance of Flow Data 
The nineteen hydraulic structures associated with the water management of the Refuge 
are shown in Figure 10. In the previous section, these structures were classified according 
to their geographical location. They can also be classified according to the direction of 
the flow as: a) inflow structures: S-5A, G-310, G-251, S-6, S-362, ACME -1 and ACME 
-2 (ACME-2 is also referred as G-94D); b) outflow structures: S-10E, S-10D, S-10C, S10A, 
S-39, G-94A, and G-94B; and c) bidirectional flow structures: S-5AS, G-301, G300, 
G-338 and G-94C. 
Discharge Data are available for the 19 structures from the DBHYDRO website 
(additional data for the S-362 station was obtained from SFWMDs personal). However, 
the data for some of the stations do not cover the complete period of record, namely from 
January 1995 to December 2004 (see Table 10). A more detailed description of the flow 
missing data is presented in Appendix G.3.

Flow data are available for this period 
Structure was in operation but data are not available 
Structure was not in operation during this period 
Table 10 shows that there are data available for the complete POR for stations S-5A, S5AS, 
and S-6. However, these stations were diverted away from the Refuge at some 
points during this period. The S-5A pump station discharged into the Refuge until August 
1999, when it was diverted to the western stormwater treatment area (STA-1W). 
Similarly, structure S-5AS and the S-6 pump were diverted away from the Refuge in June 
1999 and May 2001, respectively. The diversion of the S-6 pump represented a major 
removal of water and phosphorus loading from the Refuge (Waldon 2005). On the other 

hand, structures G-301 and G-300 started operating in August 1999. These structures are 
bidirectional and allow occasional discharge of water from the West Palm Beach Canal 
directly into the Refuge, and also release of water at the north end of the Refuge to the C51 
Canal. The water from the West Palm Beach Canal is normally discharge to STA-1W, 
and the effluent water from STA-1W is later discharged into the Refuge, approximately 
10.6 Km south of G-301 structure, through the large pumping station G-310 (3,040 cfs 
capacity), and a much smaller pumping station G-251 (Waldon 2005). Structure G-310 
started operating in May 1999. On the other hand, structures G-94A, G-94B and G-94C 
have been in operation during the complete POR. According to Waldon (2005) these 
structures are primarily for agricultural and urban water supply; they intermittently 
discharge relatively small volumes out of the Refuge during the dry season. The time 
series available from the DBHYDRO website for these stations are missing 
approximately 63 months of discharge data for each of the sites. 
For the selected POR (1995 to 2004), The DBHYDRO database presents between 2 and 6 
different time series available for each hydraulic structure, with the only exception of 
stations G-338 and S-362 that have only one time series available. As mentioned earlier, 
the DBHYDRO browser user documentation manual recommends the utilization of the 
data identified with the PREF recorder, since these time series already underwent a 
second level of QA/QC by SFWMD personnel. However, since not all the stations 
include a PREF file or the PREF file does not always cover the complete period of 
interest, all the time series available were retrieved from the DBHYDRO website and 
analyzed. Appendix B shows the discharge time series available for the hydraulic 
structures, as well as the comparisons among them (see Figures B.1 to B.84). 
Each of the available time series was reviewed, looking for outliers and discrepancies in 
the data. Tables 11 to 14 indicate the time series available for each site, summarize the 
major observations to the data, and indicate the time series that are recommended for 
future use during the Refuge modeling effort. The arithmetic mean of daily average, and 
the maximum and minimum daily average discharges were calculated for each structure, 
and are also reported in Tables 11 to 14. These tables also report the major periods of 
consecutive operational days, i.e., days of non-zero flow (this is referred as flowing 
period) and the major periods of zero-flow (this is referred as non-flowing period), 
and the modifications to the selected time series after the completion of the quality 
assurance checks. 
Based on the POR and according to the management structures operation, pumping 
stations G-310, S-6 and S-5A present the highest arithmetic mean of daily average 
inflows, with a flow close to 400 cfs. The maximum recorded daily average discharge is 
equal to 4,779 cfs through pumping station S-5A. Meanwhile, stations G-310 and S-6 
show maximum daily average discharges equal to 3,224 and 2,920 cfs, respectively. 
Structures S-39 and S-10D present the highest arithmetic mean of daily average outflows 
to the Refuge with a flow close to 180 cfs. Structures S-10C and S-10A have an 
arithmetic mean of daily average discharge (outflow) close to 145 cfs. The maximum 
recorded daily average outflow from the Refuge is 4,921 cfs through spillway S-10A.

The two files (JJ809 and TA412) present major differences. TA412 is the PREF file, 
but only covers the period from 11/2/99 to 12/31/04. The JJ809 file starts at 08/26/99,

The flow is intermittent and bidirectional. The structure is "flowing" only 18.9% of the 
Spillway 
time, with negative flow 50.1% of the time. The maximum flowing period is 30 days 
in -out 
(10/5/99 to 11/5/99), and the maximum non-flowing period is 148 days (9/14/01 to 
02/09/02). This structure started operating on late August 1999. According to Waldon

Table 15 shows the total cumulative inflows and outflows from water management 
structures into and out of the Loxahatchee Refuge. For the POR, the yearly average 
inflow to the Refuge is 579,038 acre-ft and the yearly average outflow is 576,141 acre-ft. 
For this long-term cumulative the total outflow is only 0.5% lower than the total inflow. 
The close balance between inflows and outflows through the water control structures, and 
the fact that the annual average rainfall and potential evapotranspiration (ETp) are similar 
(Abtew et al. 2005), indicates that water losses through seepage may not be significant in 
the long-term average scenario. The average annual rainfall in the entire region managed 
by the SFWMD is 52.8 inches, while the average ETp is reported to be 52.6 inches 
(Waldon 2005).

8. Procurement and Quality Assurance of Meteorological Data 
8.1 Rainfall Data
Daily rainfall data are available at different locations inside and close to the Loxahatchee 
Refuge. There are five stations inside the Refuge: 5A, S-6, S-39, WCA1ME, LOXWS 
and one station located at the Everglades Nutrients Removal Project (ENRP) site, which 
is located adjacent to the northwestern boundary of the Refuge. These six rainfall 
measurements stations are operated by the SFWMD and Data are available from the 
DBHYDRO website. There are also ten additional rain gages located adjacent to the 
Refuge. Data for these stations were provided by USFWSs personnel. The location of 
the rainfall measurements stations is shown in Figure 11. Stations S-5A, S-6, and S-39 
have daily average rainfall measurements since 1956, 1960 and 1963, respectively. The 
weather station WCA1ME has rainfall measurements since 1994, and weather stations 
LOXWS and ENRP have measurements since 1996. The aforementioned ten additional 
rain gages are located adjacent to the Refuge in Basin A and Basin B. Location of rain 
gages in Basin B (Gage 6 through Gage 10) is shown in Figure 11. Daily rainfall 
measurements from these gages are available since January 1997. Gage10 (PS-2) was 
added to this rain gage network in April 2000, and its daily rainfall Data are available 
since then. 
Historical rainfall measurements at USGS water level monitoring sites 1-7, 1-8C, and 1-9 
are also available at the DBHYDRO website. However, these rain gages are not currently 
in operation. Daily average rainfall data from these gages are available only for the 
period of 1960 to 1984. 
Availability of rainfall data for the POR (1995-2004) is shown in Table 16. This table 
also includes the information about missing data along with start and end dates of 
available periods. A more detailed description of the rainfall missing data is presented in 
Appendix G.4. 
Daily rainfall measurements from all these rain gages are plotted and presented in 
Appendix C. There are more than one time series of rainfall data available from stations 
S-39, S-5A, and S-6. Rainfall stations S-5A and S-6 have PREF time series files that 
will be used to estimate rain at those stations. Rainfall station S-39 has three time series 
files (6035, 16677, and K8674) that do not have a good agreement with each other. Time 
series 6035 and K8674 have better match with each other than with the time series file 
16677. Thus, the time series files 6035 and K8674 will be used to estimate rainfall at S39 
station. Plots showing comparison of rainfall records for different time series are also 
presented in Appendix C.

Summary of rainfall measurements from all the rain gages is shown in Table 17. This 
table indicates that the average annual rainfall records from new gages (Gage 1 to Gage 9 
in the table) are higher than the average annual rainfall from SFWMDs rain gages. Years 
with more than 30 days of missing data were not included in the calculation of the annual 
average rainfall. For years with less than 30 days missing, the total sum of rainfall was 
compared with nearby gages with complete data. If the total cumulative rainfall for the 
year with missing data was smaller than the nearby gages, then a decision was made to 
discard such a year from the calculation of the annual average of rainfall. An exception 

was made with the 1999 data for the LOXWS gage. For this year the gage has 48 days 
missing, but the total rainfall sum was higher than nearby gages and also the highest 
individual year value for the gage, and therefore it was included in the calculation 
without filling any missing day. In summary, annual average rainfall recorded from these 
new gages from the year 1997 to 2004 is 64.56 inches, whereas, average rainfall recorded 
from SFWMDs rain gages for the same period is 49.18 inches. The difference in annual 
rainfall measurements from these two different sources is about 15 inches, which is 
considerable. Such a large discrepancy must be addressed before the modeling efforts 
commence. Effort is underway to obtain RADAR rainfall estimates from the SFWMD. 
These estimates will be compared to the point gauge estimates and possibly used in the 
modeling effort. More discussion on this issue will be provided in subsequent reports. 
In terms of seasonality, more rainfall seems to be occurring during the months June-
October compared to the rest of the year. Maximum daily rainfall over the refuge was 
recorded on October 15, 1999. On that day, most rain gages recorded about 8 inches of 
rainfall, whereas stations S-39 and S-5A recorded less than 2 inches of rain.

8.2 Evaporation and Potential Evapotranspiration Data
Evapotranspiration (ET) data for the Refuge are available from the ENRP (STA-1W) site. 
Also, pan evaporation and potential evapotranspiration are available from stations S-5A 
and LOXWS, respectively. The location of these stations is shown in Figure 11, and the 
availability of data is summarized in Table 18. A more detailed description of the 
evaporation and ET missing data is presented in Appendix G.5. Time series of 
evaporation and ET measurements are included in Appendix D. A comparison between 
ET measurements from STA-1W and potential ET from weather station LOXWS is also 
included in this Appendix. This comparison shows that, in general, potential ET 
estimated from LOXWS is less than ET measurements from STA-1W. 
Figure 12 shows the ETs seasonal variation estimated from STA-1W for the POR. As 
can be observed in this figure, ET is higher during the months of March to August (with 
values higher than 4.5 inches), reaching a peak of about 6 inches in May. A regional 
evaluation of ET in the everglades conducted by German (2000) presented similar results 
to those shown in Figure 12. Annually, the average ET from the STA-1W station for the 
POR is equal to 52 inches, which is almost equal to the annual average rainfall from 
SFWMDs rain gages.

8.3 Air Temperature Data
Air temperature data for the Refuge are available from weather station LOXWS (see 
Figure 11). The available data covers the complete POR; however, there are 320 days of 
missing data from which 85 days are continuous. A detailed description of the air 
temperature missing data is presented in Appendix G.6. It should be noted that there were 
five days with temperature equal to 0C that were converted to missing data. Figure 13 
shows the temperature time series from station LOXWS including the missing and zero-
temperature days. Excluding the five days with temperature equal to 0C, the daily 
temperatures range between 7C to 30C, with an annual average of 23.4 C for the POR. 
Figure 14 shows the seasonal variation of air temperature observed at LOXWS for the 
POR. As can be observed in this figure, air temperature is higher during the months of 
May to October (with values close or higher than 25C), reaching a peak of about 27.3C 
in August. For the POR, the monthly average temperature ranges from 17.8C to 27.3C.

8.4 Wind Data
Wind speed data for the Refuge are available from weather stations LOXWS and 
ENR308 from the DBHYDRO website. For these sites, wind speed data are available for 
the complete POR, but there is not information about wind direction. The ENR308 site is 
a weather station located at the Everglades Nutrients Removal Project (ENRP), which is 
located adjacent to the northwestern boundary of the Refuge. Station S-5A also has wind 
speed measurements, but it covers only until August 1998, and wind direction data are 
also not available. Wind speed and wind direction data are available at three USGS 
stations located close to the Refuge, but data for two of these stations are only available 
for 1996 and 1997. The other USGS station has data for the period of January 1996 to 
September 1999. There is a fourth USGS station close to the Refuge, but the wind data 
are missing. More information about the USGS stations is presented in German (2000). 
Additional to the data of the aforementioned stations, wind direction along with wind 
speed data were obtained from the National Climatic Data Center (NCDC). The Local 
Climatological Data for the NCDC are collected at the West Palm Beach International 
Airport (PBI). The location of the wind stations is shown in Figure 15, and Table 19 
summarizes the availability of wind data.

For the POR, the average wind speed for stations ENR308 and LOXWS are 6.97 and 
6.59 mile/hour, respectively. The maximum recorded daily average wind speed for these 
stations are 36.87 and 38.59 mile/hour respectively. The maximum wind speed at 
ENR308 was recorded on September 4, 2004, where the maximum wind speed at 
LOXWS was observed on March 01, 2001. Average S-5A wind speed from 1995 to 1998 

is 4.67 mile/hour, which is lower than wind speed from the other weather stations. The 
average wind speed for the USGS stations 1, 3 and 4 (see Figure 15) are 3.78, 4.67 and 
4.68 mile/hour, respectively.

9. Procurement and Quality Assurance of Water Quality Data 
9.1 Water Quality Data
Water quality data for the Loxahatchee Refuge are available from five different sources: 
1) the Everglades Protection Area (EVPA) water quality monitoring sites, 2) the 
Enhanced water quality monitoring sites, 3) the District Transect monitoring sites or 
XYZ data, 4) the water quality monitoring sites located at the hydraulic structures, and 5) 
additional independent monitoring sites. Water quality data for groups 1, 2, 4 and 5 can 
be downloaded from the SFWMDs DBHYDRO database, and the XYZ data can be 
requested from the SFWMD. 
There are fourteen Everglades Protection Area (EVPA) water quality monitoring sites 
inside the Refuge marsh that were active during the period of study. These water quality 
stations were designed to monitor the physical, chemical and biological quality of the 
Refuge. Table 20 shows some of the water quality parameters that are measured in the 
EVPA stations, and Figure 16 shows the location of these monitoring sites. Most of the 
water quality variables are sampled and reported monthly; however, not all the 
parameters are measured at the same frequency. The sampling frequency of water quality 
monitoring stations is irregular. The current SFWMD monitoring programs are described 
by Germain (1998). According to Weaver and Payne (2004) the sampling frequency in 
the SFWMD monitoring stations varies by site depending on site classification, variable 
group, and hydrologic conditions. More than ten years of water quality data can be 
retrieved from the SFWMDs DBHYDRO database. It should be noted that water quality 
data at inflow and outflow control structures are typically sampled biweekly when 
flowing and monthly otherwise.

It is important to note that care must be taken while interpreting some of the variable 
names and descriptions in DBHYDRO. TPO4 and TDPO4, for example, are respectively 
total phosphorus and total dissolved phosphorus as mg/L of phosphorus (not simply 
phosphate and not as phosphate mass). 
Figure 16. Location of Water Quality Monitoring Sites Inside the Refuge. 
9.2 Total Phosphorus Data  EVPA Stations 
Based on the selected POR, total phosphorus (TP), and chloride (Cl) were retrieved from 
the DBHYDRO database for the 14 EVPA monitoring sites, i.e., stations LOX3 to 
LOX16. Figure 17 shows the location of the EVPA stations. The TP time series for each 
station are included in Appendix F1. For the POR, the sample size (number of data points 
available) varies between 65 and 122, the arithmetic averages of measured TP 
concentrations vary between 7.3 and 11.8 mg/L, and the geometric means between 6.6 

and 10.1 mg/L. The TP mean concentration for all the EVPA sites together is between 9.2 
and 9.0 mg/L (the uncertainty in this estimate is due to several values that were reported 
to be less than the limit-of-detection). Table 21 indicates, for each EVPA site, the 
arithmetic average, the geometric mean, the maximum and the minimum reported value, 
the sample size, and the start and end dates of the available data (all this information is 
according to the selected POR). This table also summarizes the major observations to the 
data and the modifications it underwent after the quality assurance checks.

9.3 Total Phosphorus Data  ENHANCED Stations 
There are thirty nine Enhanced stations inside the Loxahatchee Refuge. However, data 
for these stations are only available after June 2004, and the number of data points 
available for TP varies between just 4 and 7. The location of the Enhanced monitoring 
sites is shown in Figure 18. The arithmetic averages for the enhanced sites range from 7.8 
to 188.4 mg/L, and the geometric means from 7.4 to 138 mg/L. The TP mean 
concentration for all the enhanced sites together is 49.9 mg/L. The high values of the 
means and their wide ranges are related to the fact that some of the sites are located close 
to the rim canal, and are affected by the penetration of canal water into the marsh. Table 
22 shows a summary of the TP data for the enhanced sites, and also the major 
observations and modifications to these data.

9.4 Total Phosphorus Data  XYZ Stations 
There are eleven XYZ stations associated with the Loxahatchee Refuge, two canal 
stations (X0 and Z0) and nine marsh stations (X1, X2, X3, X4, Y4, Z1, Z2, Z3, Z4). The 
location of the XYZ stations is shown in Figure 19, and the TP time series for each 
station are included in Appendix F2. According to the SFWMD (2000) these stations 
were established along a nutrient gradient in the southwestern corner of the Refuge (see 
Figure 19) for biological and chemical sampling. Data for these stations are available 
from April 1996. The sample size for these sites varies between 107 and 142 values per 
site, for the POR. Arithmetic means of TP concentrations during the period of record 
range between 9.0 and 56.5 mg/L, and the geometric means vary between 8.1 and 49.9 
mg/L. The highest concentration values correspond to canal water, and it declines as the 
distance from the rim canal increases. Figure 20 and 21 shows the variation in the TP 
arithmetic and geometric means, respectively, with respect to the distance from the rim 
canal. In both cases, the TP concentration steadily decreases as the distance from the 
canal increases until about 1.5 Km, where the TP values become almost constant at about 
10 mg/L and independent of the distance from the canal.

Table 23 shows a summary of the TP data for the XYZ sites, and also the major 
observation and modifications to these data.

9.5 Total Phosphorus Data  Hydraulic Structure Stations 
As indicated in a previous section, for the POR that goes from 1995 to 2004, there are 19 
hydraulic structures associated with the Refuge. Water quality Data are available from 15 
of these sites (for the complete POR); only the structures G-251, G-338, S-362 and G94A 
(see Figure 10) do not have data available, and structure G-94C presents data for 
only three single days. The data for the G-251 have been requested to the SFWMD. 
Stations S-5A, G-310 and S-6 have grab samples and composite samples. The rest of the 
stations have only grab samples. For the data that was gathered as grab sample, and 
excluding station G-94C, the sample size for the period of record ranges between 81 and 
534 samples per site, with a mean equal to 177 samples per station. The TP time series 
for these stations are included in Appendix F3. The TP arithmetic means vary between 
35.2 and127.4 mg/L, and the geometric means vary between 30.7 and 113.1 mg/L 
(excluding station G-94C). The arithmetic mean for all these sites together is equal to 
80.9 mg/L. Table 24A summarizes the information regarding grab TP measurements at 
these stations, and indicates the major observations and modifications to the data after the 
quality assurance checks. The composite data are for a 7-days period, and the date 
reported is the last day of the composite. The samples were composite either by time or 
by flow. Table 24B summarizes the information about the composite TP measurements at 
stations S-5A, G-310 and S-6. For the data gathered as composite sample the sample 
size for the POR ranges between 160 and 314 samples per site. The TP arithmetic means 
vary between 55.2 and 141.5 mg/L, and the geometric means vary between 44.2 and 
124.0 mg/L. The TP time series for these stations are also included in Appendix F3 
9.6 Total Phosphorus Data  Additional Stations 
Besides the data described in the previous sections, the DBHYDRO database includes 
data for other five stations associated with the Refuge. These stations are known as 
S5AD, S6D, L40-1, L40-2 and ACME1DS. Site S5AD and S-6D are downstream of the 
S-5A and S-6 pumping stations, respectively, and L40-1 and L40-2 are monitoring 
stations on the downstream side of ACME 1 and ACME 2. The site ACME1DS is 
located in the L-40 Canal. According to Waldon (2005) when the pump (ACME-1) is 
flowing this site may not be representative of the L-40 Canal because the sampling point 
is in the discharge from the gated culverts. For these additional stations, the sample size 
varies between 56 and 119 samples per site. The TP arithmetic means range between 57.8 
and 117.5 mg/L, and the geometric means range between 51.9 and 101.8 mg/L. The 
arithmetic mean for the four sites together is equal to 86.0 mg/L. Table 25 summarizes the 
information regarding TP measurements at these stations, and indicates the major 
observations and modifications to the data after the quality assurance checks. The TP 
time series for these additional stations are included in Appendix F.

were also taken in this station. A value reported as -4mg/L on 4/4/95 was replaced 
by 4mg/L. A negative values is the convention used by the SFWMD to report 
S-5A 5/23/1995 12/28/2004 314 Irregular 141.5 124.0 460.0 4.0 
values when they are less than the detection limit. The detection limit is the 
absolute value of the number reported. 
From the 160 composite samples 19 are time composite samples (ACT) and 141 
are flow composite samples. Grab samples were also taken in this station (see 
Table 24A). This station is located at the outflow pump station of STA-1W. The 
G-310 7/18/2000 12/28/2004 160 Irregular 55.2 44.2 493.0 14.0 maximum value equal to 493 mg/L corresponds to an "extreme event" on 3/11/03. 
The 312 samples were taken as flow composite samples (ACF). Grab samples 
were also taken in this station. The maximum value equal to 722 mg/L 
corresponds to an extreme envent on 3/18/97. Besides this value, the maximum 
S-6 2/21/1995 12/29/2004 312 Irregular 80.9 68.9 722.0 16.0 
measured TP concentration is 341 mg/L. The S-6 pump station discharge was 
diverted away from the Refuge on May 2001

9.7 Chloride Data  EVPA Stations 
Ten years (1995 to 2004) of chloride (Cl) data were retrieved from the DBHYDRO 
database for the fourteen EVPA monitoring sites (see Figure 17). The sample size for Cl 
varies between 41 and 112 data points per site for the POR. The Cl arithmetic means 
range between 13.5 and 67.6 mg/L and the geometric means between 12.7 and 58.0 mg/L 
(see Table 26). The arithmetic mean for all the EVPA Cl measurements during the POR 
is equal to 31.8 mg/L. Table 26 indicates, for each EVPA site, the arithmetic average, the 
geometric mean, the maximum and the minimum reported value, the sample size, and the 
start and end dates of the available chloride data (all this information is according to the 
selected POR). This table also summarizes the major observations to the data and the 
modifications it underwent after the quality assurance checks. The time series for 
chloride are shown in Appendix F5. The relationship between TP and Cl arithmetic and 
geometry means can be observed in Figures 22 and 23, respectively. There is virtually no 
correlation between TP and Cl averages for the EVPA stations.

All the Cl samples for the EVPA stations were collected as grab samples. 

9.8 Chloride Data  Enhanced Stations 
As indicated before, there are 39 Enhanced stations inside the Loxahatchee Refuge, but 
data for these stations are only available after June 2004 (see Figure 18). The number of 
data points available for Cl varies between just 3 and 7. All the CL samples at the 
Enhanced stations were collected as grab samples. The Cl arithmetic averages for the 
enhanced sites range from 16.9 and 114.0 mg/L, and the geometric means from 16.2 to 
110.2 mg/L. The Cl mean concentration for all the enhanced sites together is 58.7 mg/L. 
As in the case of the total phosphorus, the high values of the means and their wide ranges 
are related to the fact that some of the sites are located close to the rim canal, and are 
affected by the penetration of canal water into the marsh. Table 27 shows a summary of 
the Cl data for the enhanced sites, and also the major observations and modifications to 
these data. Figure 24 and 25 show the relationship between the means of TP and Cl for 
the enhanced stations. These figures show that the TP means tend to increase as the Cl 
means increases, however a poor correlation is observed between the variables.

9.9 Chloride Data  XYZ Stations 
As indicated before, there are eleven XYZ stations associated with the Loxahatchee 
Refuge, two canal stations and nine marsh stations (see Figure 19). Chloride data for 
these stations are available from April 1996. For this period of record, the sample size 
varies between 103 and 121 data points per station. The Cl arithmetic means vary 
between 40.4 and 148.6 mg/L, and the geometric means range between 34.1 and 138.7 
mg/L. The arithmetic mean of all the Cl measurements during the period of record is 
equal to 92.7 mg/L. As in the case of TP, the Cl concentration exhibits a gradient of 
decreasing concentrations as the distance from the rim canal increases (see Figures 26 
and 27). However, as shown in Figure 26, the gradient for the TP is steeper and the 
concentrations decrease to a fairly constant value (about 10 mg/L) within the first 1.5 Km. 
The Cl concentration decreases less rapidly and it seems to drop to a relative constant-
interior value (about 50 mg/L) within 3.2 Km of the rim canal. The relationship between 
TP and Cl means for these stations are shown in Figures 28 and 29. The data in these 
Figures can be grouped into two different sets: (a) the stations close to the canal (distance 
to the canal less than 0.6 Km) that show high values for both TP and Cl, and (b) the 
stations located in the interior zone (distance to the canal greater than 0.6 Km) that show 
a almost constant value for the TP (varying between 9.0 and 16.3 mg/L for the arithmetic 
averages) and a variable Cl concentration (varying between 40.4 and 105.5 mg/L for the 
arithmetic averages). This tendency is not surprising, since the Cl is a more conservative 
substance than TP. TP concentrations are affected by biological uptake and other biochemical 
processes in the marsh, while the Cl concentrations basically decline as the 
result of dilution (SFW*-/MD, 2001). Table 28 summarizes the information for the Cl 
data at the XYZ sites. This Table indicates the major observations to the data. The Cl 
time series for each site during the period of record are included in Appendix F6.

9.10 Chloride Data  Hydraulic Structure Stations 
Chloride Data are available at 13 of 19 hydraulic structure locations around the Refuge 
for the period that goes form January 1995 to December 2004. Structures G-300, G-301, 
G-251, G-94A, G-338 and S-362 do not have data available, and the site associated with 
structure G-94C only presents data for three days (between March and April 2001). 
However, Cl data for the G-300 and G-301 may be assumed to be equal to the S-5A 
because of its proximity. Data for the G-251 have been requested from the SFWMD. 
Excluding station G-94C, the Cl sample size for the period of record ranges between 81 
and 218 samples per site, with a mean equal to 129 samples per station. The Cl time 
series for these stations are included in Appendix F7. The Cl arithmetic means vary 
between 49.7 and 148.7 mg/L, and the geometric means vary between 49.0 and 144.6 
mg/L (excluding station G-94C). The arithmetic mean for all these sites together is equal 
to 113.2 mg/L. Table 29 summarizes the information regarding Cl measurements at these 
stations, and indicates the major observations and modifications to the data after the 
quality assurance checks. 
Figures 30 and 31 show the relationships between the TP and Cl arithmetic and geometry 
means, respectively. For these stations, both the TP and the Cl concentrations are 
considerably higher than that of the interior stations. However, there is no correlation 
between the long term average TP and Cl concentrations.

Data Information (mg/L) 
Observations/Modifications to Data 
All the Cl samples were taken at a 0.5 m depth. The data for this 
station is highly variable (standard deviation= 59.3 mg/L). Some of the 
variability in Cl concentration may result from whether the water source 
is the Everglades Agricultural Area or discharge from Lake 
Okeechobee 
The average Cl value for this station is 20% lower than the average 
value for S-5A. The minimum value equal to 5.4 mg/L corresponds to 
an "extreme event" on 10/23/95. Besides this value, the minimum value 
is equal to 39.4 mg/L. The data for this station is highly variable. Flow 
at this structure is bi-directional, and variability may result from 
alteration of source water from the Refuge or S-5A pump, or the L-8 
Basin runoff (Waldon, 2005). For this station all samples were taken at 
a 0.5 m depth

10. Conclusions and Recommendations
The main goal of this report was to compile and summarize the availability of data to 
support the Refuge hydrodynamic and water quality modeling effort. TP was selected as 
the main water quality parameter to be modeled, and chloride was selected as 
conservative tracer to evaluate the model transport subroutine. Marsh elevations, rim 
canal cross-sections, water level, discharge, rainfall, temperature, evapotranspiration, 
wind, TP and Cl data were gathered and evaluated. 
Overall, it is concluded that the available data is sufficient to achieve most of the 
modeling goals. In other words, the available data is sufficient to develop the boundary 
conditions that will force the hydrodynamic and water quality modules of the model. 
Data is also available for calibration and validation of the numerical model. 
Additional specific conclusions regarding the available field data include: 
o Data describing the interaction between surface and ground water is generally 
unavailable. However, there are estimates and studies that approximate leakage 
rates through the rim levee, and the recharge to groundwater from the marsh 
interior. A more detailed discussion about the surface-ground water interaction and 
the approach to address this issue will be provided in companion reports. 
o Wind direction data is only available at the West Palm Beach International Airport 
(PBI) station for the POR. There are wind-direction data available at three local 
stations but for only limited time (two years). 
o Atmospheric deposition data have not been discussed at this time. These data are 
currently being collected and evaluated. Even though, there is a good amount of 
data on both wet and dry deposition in the Everglades, the available time series 
have significant gaps due to instrumental failures and sample contamination (Ahn, 
1999). The initial approach in this modeling effort will be to use a constant dry 
deposition and a constant wet rain concentration, and to perform model 
sensitivity analyses to determine whether or not this approach is adequate. 
o It should be noted that there are no velocity measurements in the rim canal or in the 
interior marsh. Therefore, the transport module of the numerical model will be 
evaluated only through the ability to reproduce the spatial and temporal distribution 
of the conservative tracer.
