L-40 Canal Sediment Elevation Study: Initial Report 
Summary 
There is a concern that discharge from STA-1E may result in re-suspension of high-
phosphorus sediments that have accumulated on the bottom of the L-40 Canal over the 
years since its construction in the early 1950s (Light and Dineen 1994). It is hypothesized 
that this sediment and phosphorus may then be entrained into the Arthur R. Marshall 
National Wildlife Refuge (Refuge) marsh. This report summarizes initial findings of 
sediment elevation surveys in the L-40 Canal. The data presented here precede STA-1E 
discharge, with the exception of 2 weeks of emergency stormwater pumping in 
September 2004, and small seepage and maintenance pumping. It is observed that canal 
sediment elevation can be repeatedly measured with a precision of less than or equal to 
0.1 foot (1 standard deviation). Future studies will assess changes in sediment elevation 
following significant STA-1E pumping. 
Introduction 
In FY04, Congress appropriated funds to the Arthur R. Marshall Loxahatchee National 
Wildlife Refuge (Refuge) for water quality monitoring and modeling. The work reported 
here is a part of that larger monitoring effort (Brandt et al. 2004), and supports the 
development of a better understanding of mechanisms that impact surface water total 
phosphorus concentrations in the Refuge. These sediment elevation studies are a part of a 
Cooperative Ecosystem Studies Unit (CESU, see http://cesu.org/) cooperative agreement 
project between the U.S. Fish and Wildlife Service and the University of Florida 
(Principal Investigator Dr. Samira Daroub). 
Sediments in canals throughout the Everglades Water Conservation Areas (WCAs) 
sequester large quantities of phosphorus (Daroub et al. 2002). Concerns have been 
expressed by Refuge staff related to the discharge from STA-1E affecting distribution 
and transport of L-40 Canal sediments and associated phosphorus. This monitoring 
project is intended to provide information related change in canal sediment elevation and, 
thus, in sediment mobilization within the L-40 Canal. Although studies by Dr. Daroub 
and her research team have established that canal sediments are spatially variable 
throughout the WCAs, little is known about temporal variability of sediment depths. The 
monitoring study described in this report will, when completed, characterize temporal 
variation in canal sediment elevations in response to alteration in canal discharge. 
Specifically, this study monitors changes in the surface elevation of sediments within the 
L-40 canal (Fig. 1) prior to and following commencement of discharge from the STA-1E 
discharge pump station, S-362. At the time of initial drafting of this report, September 
2005, four pre-discharge surveys have been performed on cross-sections of five transects. 
The project plan calls for six surveys per year (approximately bimonthly) to be performed 
over a three-year (36 months) period. This report covers the first four surveys.

Construction of the L-40 canal on the east side of the Refuge during the 1950s initiated 
the complete isolation of the Refuge from its original watershed (Light and Dineen 1994). 
The system changed from a dynamic flow-through, sheet-flow driven fluvial system to an 
impounded marsh. Today, pumped stormwater and any entrained canal sediments may 
intrude into the interior wetlands of the Refuge resulting in adverse impacts from 
nutrients and other contaminants. 
The study site for this research is near the confluence of the STA-1E discharge channel 
and the L-40 Canal on the east side of the Refuge in Palm Beach County, Florida. The 
construction of STA-1E is being managed by the U.S. Army Corps of Engineers 
(USACE). Construction on the inflow and outflow pump stations commenced in May 
2000 and September 2000, respectively, and both were completed early 2003. Full 
startup commenced in September 2005. Once in operation, treated water from STA-1E 
will be discharged into the L-40 canal through the S-362 pump station. 
Prior University of Florida, IFAS research work has demonstrated that farm canals have a 
significant impact on the total P concentration discharged from EAA farms (Daroub et al. 
2002; Stuck 1996). It is reasonable to inquire whether the canals in the WCA water 
distribution network downstream of the STAs could have a similar impact, particularly in 
view of the low concentration of P that will be discharged into them as STA technology 
matures. Because of the potential P load within these canals, questions have been raised 
regarding the effect that future flows from operational STAs may have on sediment re-
suspension and nutrient transport to downstream ecosystems. 
Methods 
Five transects located on the L-40 Canal are being monitored in this study. These 
locations were previously surveyed in 2002 (Daroub, et al., 2002) and it is of interest to 
compare that data with new data from this project, especially after heavy bypass and 
pumping due to Hurricanes Frances and Jeanne in September and October 2004 (USFWS 
2005). The final decision on the location of the study sites was made in cooperation with 
IFAS and Refuge personnel. Two transect sites were located north, and three south, of the 
STA-1E discharge canal (Table 1, Fig. 2). This set of sites was selected from a more 
extensive set measured in the previous IFAS study. Site names are consistent with those 
used in the previous study. Selected transect locations were determined by GPS for future 
reference. Each transect location was marked by rebar posts permanently installed at the 
waters edge on both sides of the L-40 Canal. 
At each site an arbitrary elevation reference mark was established a short distance above 
the water surface. During each study the vertical distance from the mark to the water 
surface was measured to the nearest 0.01 ft (i. e. a tapedown measurement was 
performed). Approximate elevation of the tapedown marks at each site was estimated by 
adding the tapedown length to the surface water elevation at the G-94C headwater site 
measured in the February 2005 studies. For each survey, the water surface elevation at 
the site was estimated as the tapedown elevation minus the tapedown length. Sediment

elevation was then estimated by subtracting depth to consolidated sediment (DCS) from 
water surface elevation. 
At each site, for each visit, water surface elevation relative to the arbitrary elevation of a 
fixed mark is determined by tapedown measurements from this permanent mark. The 
tapedown length is the measured vertical distance from the mark to the water surface. 
Stage measured at the1-8C staff gauge is recorded for reference, but in this study it is not 
adequate to precisely determine water surface elevation at the sites because wind or flow 
may cause a surface slope in the canal between the 1-8C site and the study site which 
could vary excessively between sampling dates. 
Depth to consolidated sediment from the water surface is measured from a small boat. 
Lateral distance across the canal is measured along a taut cable extending between the 
posts. The cable is attached to an anchor stake, passed over a nail or hook on the post, 
extended across the canal, and similarly anchored on the opposite bank. The cable is 
marked to provide distance measurements from the bank, and, as a safety measure, 
visibility of the cable is enhanced using flagging tied to the cable. Initial measurements 
were performed at 2.5 ft (0.762 m) intervals (stations) across the section to provide at 
least 30 measurements. Subsequent surveys measured at 5 standardized stations located 
30, 40, 50, 60, and 70 ft (9.14, 12.19, 15.24, 18.29, and 21.34 m) from the interior post 
across the section. Consolidated sediment depth at each transect station is measured with 
a calibrated submersible footpad. Depth of the sediment surface below the water surface 
is determined by carefully lowering the neutrally buoyant submersible footpad until it 
rests on the sediment surface. 
Depth to consolidated sediment relative to the arbitrary datum of the staff gauge or mark 
on the post is calculated for each measurement by adding depth to the tapedown reading. 
Four surveys are reported here, and future measurements will be performed at least six 
times per year (approximately bimonthly) over the remainder of this three year project. 
All measurements are estimated and recorded to within 0.02 foot (6 mm) where possible. 
Results and Discussion 
Site selection and installation of permanent posts on both sides of the L-40 canal was 
delayed due to problems caused by hurricanes Frances and Jeanne in 2004, but was 
completed by early 2005 (Tables 2-3). The first survey was performed in February 2005, 
and additional surveys were performed in April, July, and September 2005. The first 
survey in February measured depth to consolidated sediment along transects at 2.5-foot 
horizontal spacing (Fig. 3). Because of constrained time and available effort, subsequent 
surveys measured depth only at distances of 30, 40, 50, 60, and 70 feet from the interior 
post using a taught line stretched between the posts. An additional station at 75 (22.86 m) 
feet was added to transect L40-19 because rocks at the 70-foot station reduced the 
repeatability of the depth measurement.

The University of Florida Everglades Research and Education Center (EREC) provided 
all field equipment used during the sediment surveys. Dr. Orlando Diaz organized and 
led the surveys crews, and all survey personnel were provided by the EREC. 
Precision of elevation measurements is estimated here under the assumption that no 
change in sediment surface elevation occurred over the period of these initial surveys. 
Precision of elevation measurement as characterized by the temporal standard deviation 
of measurements at single stations and over station average elevations appears to be near 
or below 0.1 foot (0.03 m). Within this measurement precision, consolidated sediment 
elevations have been stable throughout the 2005 studies (Table 2, Fig. 4). 
Cross-sectional elevation also appears to have changed little since the 2001 study by 
Stuck and others reported in Daroub et al. (2002). Direct comparison of these earlier data 
with data from the current study is confounded by uncertainty of water surface elevation. 
The previous study estimated stage everywhere in the perimeter canals using the G-310 
pump station tailwater stage. Additionally, no fixed tapedown marks were established in 
these earlier studies. In spite of these limitations, figures 5(a) through 5(e) demonstrate 
the similarity between these earlier cross-sections and those collected in February 2005. 
Thus, it is concluded that the sediment surface elevation was relatively unchanged 
between the 2001 and 2005 studies. 
These figures also plot elevation of the hard substrate underlying soft sediment 
determined by the use of a penetrometer in 2001. It is assumed that these soft low-density 
sediments measured and characterized in the earlier study are susceptible to entrainment 
during relatively high velocity flow events. At this time, there are no plans within this 
study to perform additional penetrometer measurements at these sites. 
No statistical treatment of the elevation data has been completed at this time. It is 
anticipated that statistical change analysis will be reported in the next report on this 
project in late 2006. At that time, data from studies following startup of STA-1E should 
be available.
