This data analysis was deve loped in coordination between the St. Andrew Bay Resource

Management Association’s (R MA) Baywatch Program and th e Northwest Florida Water

Management District (NWFWMD) . The objective was to comp lete an analysis of all

Baywatch water quality data for the St . Andrew Bay system from 1990 through 2006.

These analyses are intended to further th e Program’s understanding of the St. Andrew

Bay system and their Baywatch water quality monitoring program. Each of the three

techniques employed in the analys is of these data were used to provide a distinct look at

the cumulative data. The statistical summaries provided a thorough de scription of the

data that allowed for a careful examination of individual sites. This showed the extremes

of the variability in the data within each site. The site statistical differences showed intersite variability by monitoring category. This approach provided a depiction of data

differences and similarities of the two data types, but not differences for the overall data

(all sites together). The evaluation of the data via percentiles not only showed data

placement relative to all the data for a given parameter combined, but also represented all

monitoring categories in the same display. Fu rther examination for select cases of data

extremes with correlation analysis showed the influence of time on various water quality

parameters. Although few significant trends were observed, potentially important

associations of time were found with some pa rameters. Percentiles and correlation with

time may prove to be a valuable approach to reveal ecological or system-wide

importance.

### Introduction

The St. Andrew Bay Ecosystem

As previously described by Notestein (2007), St. Andrew Bay is a relatively large

(~69,000 acres) Gulf of Mexico estuary along the Florida panhandle. It is contained

primarily within Bay County Florida, but includes portions of Walton, Washington,

Jackson, Calhoun, and Gulf Counties (Figure 1) . This highly saline ecosystem contains

important marine and estuarine habitats incl uding large expanses of seagrasses and salt

marsh. A high diversity of plant and animal life has been documented in St. Andrew Bay,

making it a nationally significant bay system (Keppner 2002). Taken together, the St.

Andrew Bay system is extremely important to the people of Bay County and their

international visitors. The services this sy stem provides include, but are not limited to,

the local water supply, world-wide tourism, commercial and recreat ional fisheries, and

all manner of water recreation.

Like many coastal lands in Florida, mark ed development has occurred in the St.

Andrew Bay watershed (~732,000 acres). Pl ans currently exist for unprecedented

development in this area because of its inherent natural beauty and location.

Environmental management activities for this system are subject to several private,

county, state and federal groups.

- 1 -Figure 1. The St. Andrew Bay watershed ecosystem primarily within Bay County Florida, but including por tions of Walton, Washington, Jackson, Calhoun, and Gulf
Counties.

- 2 -- 3 - Starzinger (2003) described the system well as follows. The St. Andrew Bay

system has an average depth of approximately 17 feet, and depths as much as 65 feet

have been recorded. He, like many, found the system unique in several respects. The

natural tributaries are relatively clean, a nd several are spring-fed. No major rivers

terminate in the watershed and therefore sediment burdens are quite low. As a result of

these conditions, the estuary e xhibits high water clarity and high salinity. This is the only

bay system found along the northern Gulf of Me xico that is both an inland embayment

and lacks large river system inputs. This cr eates a unique environment that allows for

extensive bay-wide beds of seagrass speci es such as turtle grass (Hackney 1992).

St. Andrew Bay Resource Management A ssociation Baywatch Sampling Effort

Since 1990, the St. Andrew Bay Resource Management Association (RMA) has

maintained and expanded a local water samp ling effort. Today 76 sites are routinely

sampled. Sites are shown in Figures 2 thr ough 8 along with stations for which sampling

has been discontinued (a detailed station lis t in provided in the appendix). The RMA will

continue long-term implementation and coor dination of the Baywatch volunteer water

quality monitoring program. This program was initiated to m onitor water quality

conditions throughout the St. Andrew Bay syst em. Site monitoring varies with the

rationale behind the site’s se lection. To date, the rationa le has supported three major

groups, paraphrased here as: University of Florida Lakewatch sites (UF), General

Baywatch monitoring sites (BW), and Seagrass monitoring sites (SG).Figure 2.

- 9 -Briefly, the data collected can be su mmarized as follows. The measurements

recorded for each station included water depth (ft for UF and BW, m for SG), Secchi disk

depth (ft for UF and BW, m fo r SG), water temperature ( o C), dissolved oxygen (mg/L),

turbidity (NTU), salinity (ppt), pH (standard unit s), chlorophyll a (ug/L), total nitrogen

(ug/L), and total phosphorus (ug/L). Add itional information collected at sites has

included air temperature, tides, rainfall, ti me of sampling, state of the seas, and area

weather conditions.

Most stations were visited monthly, except for the years 1996 through 2000, when

quarterly sampling occurred for University of Florida (UF) and Baywatch (BW) sites.

On-site measurements were made using calib rated datasondes or i ndividual test sets

calibrated and maintained by RMA’s centr al laboratory. Chlorophyll and nutrient

samples collected at University of Florida (UF) stations were sent to the UF professional

laboratory. Other collected samples were retu rned to RMA’s central lab, the Bay County

lab, or the Florida Department of Environmental Protection lab where trained personnel

processed them using speciali zed equipment and standard protocol. The water quality

data discussed in this repor t were collected between Febr uary 1990 and December 2006.

Objective

This data analysis report was develope d in contract between the RMA and the

Northwest Florida Water Management District (NWFWMD). The contract specified that

a scientist would be se lected to complete an analysis of all Baywatch data from 1990

through 2006. Subsequent reports will fo llow until 2010 for the purpose of further

exploring the trends revealed in this cumulative data analysis.

These analyses for the comprehensive Baywatch data set are intended to further

the Program’s understanding of the St. Andr ew Bay system and th eir Baywatch water

quality monitoring program. It is the authors’ sincerest hope that th e findings herein are

valuable to the numerous volunteers and partic ipants in this program over the years and

that this may, in some small part, contribu te to their vast an d impressive effort.

### Methods of Statistical Data Analysis

Preliminary Database Reformatting

Data review and formatting included altera tion of the data set for analysis with

Statistical Analysis Software (SAS Institute 2007, version 9.1). This formatting involved

the removal of all data entries described as data not being required at the site, data not

collected at a certain time for various reasons , and data that was lower than detection

limits or beyond the capability of th e sampling apparatus (e.g. a phosphorus

concentration lower than the lowest detectable level or a Secchi depth greater than 5 feet

when the depth was only 5 feet). Additionally, obviously erroneous data were omitted

(i.e. pH of 81.0 or turbidity of 800.1 NTUs). Each of these entries were replaced by the

typical “.” indicating missing data points to the software program. These omissions are

revealed by inconsistent sample sizes in the data summary tables for the various

parameters even within a given site. Paramete rs or entire sites were also omitted when

scant data was available (n<10 fo r a parameter or entire site) at a site. Further, specific

conductance was omitted due to its redundancy with salinity in the majority of sites.

Site Statistical Summaries

Preliminary analysis included descriptive statistics for all monitored sites (unless

excluded as described above). Data statistical summaries were created by site (Results

Tables 1-72). Stations have been described by current st ation number, former station

number, and qualitative name or description, along with t ype of site (University of

Florida Lakewatch sites and general Baywatch sites, and years sampled, followed by total

years sampled. The data were summarized by water quality parameter including the

sample mean, standard deviation as a measur e of data variability, sample size for the

parameter, range of measures for the variab le (highest and lowe st observations), and

whether the data had a normal distributi on which has implications for statistical

evaluation methods (Shapiro-Wilks No rmality Test, SAS, Inc. 2007).

- 11 -Statistical Differences

Sites were evaluated by water quality pa rameter for statistically significant

differences (General Linear Model, GLM on ranked data, SAS, Inc. 2007). Data were

first examined for whether differences existed among sites ( α =0.05) for each water

quality parameter for currently monitored sites. In cases where statistically significant

differences existed, multiple range comparis on tests were performed to determine which

sites were statistically distinct from each other (Student-Newman-Keuls Multiple Range

Test, MRT on ranked data, SAS, Inc. 2007). This multiple range comparison allowed for

viewing which sites specifically are statisti cally significantly differe nt from one another

and which are not statistically significantly different by parameter and site. Results will

follow in Tables 73-99.

Data Review by Percentiles and Correlation Analysis with Time

In an effort to provide an ecologically fo cused depiction of the data, the data were

reviewed by their placement within the cont ext of the entirety of the data for each

parameter. The central tendencies (means) were compared to the distribution of the data

as revealed by percentiles (i.e. 90% of the data are less than this number, 25% of the data

are less than that number). When the central tendency of a parameter for site was

compared to these percentiles derived from poo ling (a collection of all data across groups

including UF and BW) all data, the results were presented in a spatial relationship. In

these cases a site with a central tendency greater than the 90 th percentile would indicate

that its average measure was greater than 90% of all readings taken in this program over

all years in data groups (UF and BW). The ev aluation of the data via percentiles not only

showed data placement relative to all the da ta for a given parameter combined, but also

represented all data groups (UF and BW) in the same display. It was felt that this

provided a more St. Andrew Bay- centered evaluation of the da ta that would better serve

- 12 -the purposes of this analysis than using Stat e-wide water quality standards that have an

inherent need to account for far greater vari ability among Florida waters. Site means for

each parameter were examined where adequate (generally n>10) water quality data were

available.

Data found to fall in the data extremes we re subjected to correlation analysis of

the water quality parameter with time in cu mulative days (modified Julian days) to

illustrate trends in the data for that site ove r time. All correlation analysis results are

presented, but statistically significant correlations ( α =0.05) are shown in bold for

emphasis (Spearman Correlation Analysis/, SA S, Inc. 2007). Results follow and are

provided in Figures 9- 18 and Tables 100-110.



### Results

Site statistical summaries, statistica l differences, and evaluation by cumulative

percentiles were created for a ll data groups. However, analysis of the data revealed

further database reconciliation needs for the Seagrass data gro up sites. For this reason,

these sites were subsequently removed from the results and will be provided with the

seagrass monitoring data evaluation after th e data has been reconciled with existing

records. Complete results for University of Florida and Baywatch sites are provided

below.

### Discussion

Preliminary Database Reformatting

Ultimately, data used in the analysis in cluded 42 University of Florida Lakewatch

(UF) sites, 30 general Baywatch (BW) sites, and 24 Seagrass monitoring sites. However,

due to database reconciliation issues the Seagrass site monitoring data was omitted from

these results and this discussion.

Site Statistical Summaries

Statistical summaries dem onstrated variability among sites for almost all water

quality parameters measured. The number of samples per site varied considerably as

well. The data summary tables provide a r obust summary of the sampling efforts over the

years for these sites and parameters. Th e statistical summaries provided a thorough

description of the data that al lowed a careful examination of i ndividual sites. The test for

whether the data distribution fell in a norma l “bell-shaped” curve (Normality) showed all

parameters to be non-normally distributed in at least some cases. Therefore, the data were

examined for differences using non-parametric techniques appropriate for these data.

Statistical Differences

The variability observed in the station summaries was evident in statistical

differences among sites for almost all water quality parameters. St atistical differences

were observed often within respective data gr oups (UF and BW). Differences were not

found among sites for the parameters temp erature (surface-UF and bottom -UF and

bottom-BW). Differences were also not observed for pH (botto m-BW). All other

parameters exhibited means separation (were different among sites) within each data

group. This approach provided a depiction of data differences and similarities by the two

data types, but not differences for th e overall data (all sites together).

- 134 -Data analysis for differences among site s was performed on ranked data (number

assignment by data value within the context of all data am ong sites) because of the nonnormal distribution of the data. The lower stat istical power (ability to show statistical

difference), inherent in non-parametric an alyses, was overcome by the power provided by

the robust data set collected by the Baywatch volunteers. This is evident in the relatively

small differences revealed as statistically significant. This supported the assumption that

data transformation was not necessary to achie ve ample ability to demonstrate statistical

differences among sites. However, high statisti cal power can, in some cases, fall short of

demonstrating ecologically important differences among sites, despite its importance in

showing the inter-site similarities and differences for monitoring purposes.

Data Review by Percentiles and Correlation Analysis with Time

In an effort to provide an ecologically fo cused depiction of the data, the data were

reviewed by their placement within the cont ext of the entirety of the data for each

parameter. The central tendencies (means) were compared to the distribution of the data

as revealed by percentiles (i.e. 90% of the data are less than this number, 25% of the data

are less than that number). When the central tendency of a parameter for a site was

compared to these percentiles derived from poo ling (a collection of all data across groups

UF and BW) all data, the result s were presented in a spatial relationship. In these cases a

site with a central tendency greater than the 90 th percentile would indi cate that its average

measure was greater than 90% of all readings taken in this program over all years in both

data groups (UF and BW). The evaluation of the data via percentiles not only showed

data placement relative to all the data for a given parameter combined, but also

represented both data groups (UF and BW) in the same display. It was felt that this

provided a more St. Andrew Bay- centered evaluation of the da ta that would better serve

the purposes of this analysis than using Stat e-wide water quality standards that have an

inherent need to account for far great er variability among Florida waters.

Several areas of the St. Andrew Bay waters hed repeatedly showed that they were

out of synchronicity with the remainde r of the bay. The Grand Lagoon area of St.

Andrew Bay was routinely different than th e remainder of the bay for its lower secchi

- 135 -depth measures, and its higher tu rbidity, nitrogen, and chlorophyll a , but most notably its

higher total phosphorus measures. Powell Cr eek East was low for secchi depth and

dissolved oxygen and high for turb idity, nitrogen and chlorophyll a relative to the whole

of the data. Lake Powell was high for phosphorus, nitrogen, and chlorophyll a . The

lower portion of Deer Point Lake had high levels of phosphorus. Water quality

measurements taken in West Bay and its as sociated Crooked Creek and Burnt Mill Creek

were higher for turbidity, ch lorophyll and total phosphorus (West Bay only), and lower

for secchi depth and dissolved oxygen (creeks only). Military Point was found to be

relatively higher for total phosphorus when co mpared to the remainder of East Bay.

North Bay was also relatively higher for turb idity compared to the rest of the bay. A

number of bayous were also more often in the extremes of the data, including Lynn

Haven Bayou (low secchi depth and dissolv ed oxygen, high turbidity), Beatty Bayou

(low secchi depth, high turbidity), Mill Bayou (low secchi depth, high turbidity), Fannin

Bayou (high turbidity), Posten Bayou (low secchi depth), Watson Bayou (low dissolved

oxygen and secchi depth, high turbidity), Massalina Bayou (low dissolved oxygen and

secchi depth), Johnson Bayou (low dissolved oxygen and secchi depth), Callaway Bayou

(high turbidity).

Evaluation of areas with means above the 90 th percentile or the 75 th percentile

(below the 10 th or 25 th for Secchi depth, oxygen, or salinity) were further examined by

comparing the parameter measures with time via correlation analys is. This was done to

see if significant associations existed. If significant associations were found (in bold for

emphasis with the figures) changes in the m easures of the parameter over time could be

viewed as increasing (positive “r”) or decreasing (negative “r”). This was less

conclusive, but most parameters did have site s with significant correlations (associations)

with time. One particularly noteworthy positiv e correlation with time was the association

of total phosphorus with tim e in central Grand Lagoon (Grand Lagoon 3 and Grand

Lagoon 4). Correlation analyses indicated th at turbidity increased over time in the

following areas: North Bay, Lower Fannin Ba you, West Bay, East Bay, Upper Johnson

Bayou, and Powell Creek East. Secchi depth had a negative correlation with time

(meaning water clarity has decreased ove r time) in Grand Lagoon (Grand Lagoon 1 and

Grand Lagoon 2), Lower Crooked Creek, a nd Lower Posten Bayou. Dissolved oxygen

- 136 -levels decreased significantly over tim e in Johnson Bayou and Upper Watson Bayou.

Additionally, there were several potentially improving areas for some parameters,

including secchi depth in Upper Watson Bayou, Upper Massalina Bayou, Upper Burnt

Mill Creek and Lower Warren Bayou. Dissolved oxygen levels improved over time in

Massalina Bayou and Lower Watson Bayou. Nitroge n levels also improved over time in

Lake Powell (Powell 1 and Powell 4). U nderstanding the circumstances surrounding

changes in these water quality parameters at the select locations ma y prove beneficial to

the Baywatch Program.



### Conclusions

These data analyses each provided a distin ct look at the St. Andrew Bay Resource

Management Association’s cumulative data from their Baywatch Program for the years

1990 to 2006. The statistical summaries provided a thorough description of the data that

allowed a careful examination of individual sites. This showed the extremes of the

variability in the data within each site. The si te statistical differences showed inter-site

variability by site type (UF versus BW). The high statistical power resulting from the

large sample sizes caused small differences in water quality parameters to be statistically

distinct in many cases. This approach provided a depiction of data differences and

similarities by the two data types, but not differences for the overall data (all sites

together). The evaluation of the data via percentiles not only showed data placement

relative to all the data for a given paramete r combined, but also represented both data

groups (UF and BW) in the same display. Furt her examination for se lect cases of data

extremes showed the influence of time on various water quality parameters. Although

few significant trends were obs erved, potentially important associations of time were

found with some parameters. Percentiles and correlation w ith time may prove to be a

valuable approach to reveal ecological or system-wide importance.

As stated in the objectives at the beginni ng of this report, these analyses for the

comprehensive Baywatch data set are intended to further the Program’s understanding of

St. Andrew Bay system and their Baywatch wa ter quality monitoring program. It is the

- 137 -authors’ sincerest hope that the findings he rein are valuable to the numerous volunteers

and participants in this program over the ye ars and that this may, in some small part,

contribute to their vast and impressi ve effort and represent them well.



### Recommendations

The Seagrass data should be reconciled with the data sheets to ensure accuracy and then

subjected to statistical analysis.

Statistically significant diffe rences among sites provided somewhat limited insight into

the data and repeating this analys is may not be of added value.

Percentiles and correlation with time may prove to be a valuable approach to reveal

ecological or system-wide impor tance and warrants repeating.

Examination of specific water quality standard violations by parameter and site may be

desirable to better understand the watershed’s status in terms of impaired waters as

designated by the State of Florida.

Evaluation of the sources of variability w ithin the data, such as seasonal variation,

freshwater inflow, rainfall, population etc., or the relationship between secchi depth and

turbidity may provide a better understanding of some water quality parameters and

should be explored.
