Introduction
The Suwannee River Water Management District (SRWMD) established an ambient
surfacewater quality monitoring network in 1989, as a priority project of the Surface Water
Improvement and Management (SWIM) program. The network’s purpose is twofold: to
determine the water quality status of the priority water bodies within the District, and to
identify changing conditions in water quality.
The network provides water quality data from water chemistry and aquatic biological
samples. Analysis of the data identifies seasonal variations and long-term trends in water
quality and helps determine if land use practices affect water quality and aquatic ecological
communities.
Surfacewater Quality Network
The network includes a total of 67 stations sampled for baseline water chemistry (Figure 1).
The network includes 67 water chemistry stations, 23 aquatic biology stations, and 29
bacteria stations (Table 1). Table 2 shows the network parameter list. Most stations are
co-located with District or U.S. Geological Survey discharge stations.
Biological Monitoring Network
Over the past decade, the concept of water quality has expanded beyond
consideration of the substances dissolved or suspended in the water. Water quality
now refers to the overall ecological integrity or “health” of a river, lake or estuary,
which includes hydrology, water chemistry, habitat quality and biology. An important
part of the District’s surfacewater monitoring program is sampling of different types of
aquatic fauna and flora to evaluate the health of our surface waters. Both nationally
and at a state level, it is now recognized that an effective surfacewater quality
monitoring program must include biological sampling to get a true picture of “water
quality”.
In the District’s monitoring program, two groups of aquatic organisms are sampled:
benthic invertebrates and algae. These two groups of organisms have been used for
many years to assess water quality. The methods used to sample them are wellestablished, and it has been shown scientifically that populations of these organisms
exhibit characteristic responses to various kinds of pollution stress.
Benthic invertebrates are generally small, invertebrate animals which live on or in the
bottom environment of a river, lake, or estuary. Benthic refers to bottom-dwelling.
Examples of these animals are snails, clams, crayfish, shrimp, aquatic insects, and
aquatic worms. We use several types of sampling gear to collect benthic
invertebrates. The two most commonly used gear types in our program are HesterDendy multiplate samplers (in larger rivers such as the Suwannee and Santa Fe),
and D-frame dip nets (in smaller streams which can be waded). The Hester-Dendy
samplers are an artificial substrate. These are suspended in the water for 4

weeks. During this time, the samplers are colonized by various invertebrates. After
the 4 week period, the samplers are retrieved, returned to the lab, and analyzed. Dip
nets are used in shallow streams which can be waded. Our technicians spend 10
minutes with the net sampling a length of stream. Invertebrates collected in the net
are picked out, and they try to collect at least 100 organisms. These are returned to
the lab for identification of the animals.
The algae sampled in the District’s monitoring program are microscopic plants found
in all rivers, lakes and estuaries. In rivers, the District samples periphytic algae;
those living attached to hard surfaces. We use floating racks of glass microscope
slides to collect these periphytic algae. Similar to the Hester-Dendy samplers, these
are artificial substrate samplers which are suspended in the water for 4 weeks, then
retrieved and analyzed.
DEFINITIONS OF BIOLOGICAL METRICS
The data from the aquatic biological sampling are presented as various numeric
scores, or metrics, which are quantitative measures of the biological communities.
An analogy to how these values describe biological “health” in surface waters is the
various indices (or metrics) which define the condition or health of the nation’s
economy. The Dow Jones Industrial Average and the Consumer Price Index are
numeric measures by which the condition of the national economy is measured. In a
similar way, the biological metrics describe the status or health of the biological
communities in our surface waters.
The metrics presented in this report are:
Benthic Invertebrate Taxa Richness - the total number of taxa (different kinds or
species) of benthic invertebrates present. Higher numbers mean more taxa present,
which generally reflects a healthier benthic invertebrate community due to better
water quality and habitat conditions.
Benthic Invertebrate Diversity - an index which describes the composition of the
benthic invertebrate community in terms of the number of taxa present and the
extent to which the community is dominated by few or many taxa. Higher numbers
mean higher diversity in the invertebrate community; meaning that the community is
composed of an even mix of many different taxa. Lower diversity means that fewer
taxa are present or that the community is dominated by only one or a few taxa.
Lower diversity is generally indicative of some type of human disturbance or
pollution.
Periphytic Algal Taxa Richness - the total number of taxa (particular kinds or
species) of periphytic (attached to underwater objects) algae present. Higher
numbers mean more taxa present, generally indicative of better water quality.

Results and Discussion
BIOLOGICAL MONITORING
Tables showing summaries of the biological metrics for each of the active biological
monitoring sites are shown in Appendices C through E. Note that at some sites
(those on the Suwannee and Santa Fe), both invertebrates and algae are monitored,
while at other sites (those on other rivers) only invertebrates are monitored. In
general, the biological data support the conclusions derived from the water chemistry
data. Sampling sites which have fair water quality also tend to have lower scores for
one or more biological metrics.
HYDROLOGIC CONDITIONS DURING WATER YEAR 2003
(October 1, 2002 through September 30, 2003)
Annual streamflow for the 2003 water year in the Suwannee River basin ranged from 90 to
233 percent of the long-term mean annual flow. Highest flows in the main stem of the
Suwannee occurred during mid- to late March as a result of the El Nino frontal conditions
which produced significant rain events beginning in December. In the Santa Fe sub-basin,
highest flows also occurred during mid-March. Rainfall for the 2003 calendar year ended up
about 1 inch above the District, with significantly greater than average amounts in February
and March, but with sizeable deficits in January, April, November and December. Record
monthly low flows from the preceding drought conditions of 1998-2002 persisted through
November 2002 at several stations on the lower Santa Fe and Suwannee Rivers.
Most stations remained above average during the remainder of the year after the March
flooding, but the lower Santa Fe River dropped to below average levels again from May
forward. The Suwannee River, while much lower than average, did rebound from the
previous year’s record low levels. Coastal rivers experienced a wet year, with near-record
levels occurring in February on the Fenholloway River and with higher than normal amounts
again through the summer months.
Mean monthly flow for the 2002 and 2003 water years at the Suwannee River at Branford
and the Santa Fe River near Fort White, are shown on Figures 2 and 3, respectively, along
with the long-term mean monthly flow at those gaging stations.
Some qualification is required for the Suwannee River near Wilcox data. As the most
downstream long-term station on the river, it has served as the river’s primary integrator site
for the purposes of water flow and quality assessments. During low flow periods, the gaging
station is subject to variable backwater due to tidal influence. Since 1951, flow has been
calculated by the variable backwater method, utilizing an auxiliary slope station 9 miles
downstream. In 1999, a new method of calculation, index velocity, was implemented as a
result of technological advances.
A preliminary comparison of the two methods indicates that the index velocity method will
compute a lower flow than the variable backwater method. Over the past water year, this
difference has been as great as 1,000 cubic feet per second—a significant portion of the
overall flow at Suwannee River near Wilcox.

NUTRIENT LOADINGS FOR WATER YEAR 2003
In water year 2003, 4,591.4 tons of nitrate-nitrogen and 1,909.9 tons of total phosphorus
were transported to the Gulf of Mexico by the Aucilla, Econfina, Fenholloway, Steinhatchee,
Suwannee, and Waccasassa Rivers (Table 3). Of the total nitrate-nitrogen and total
phosphorus that were transported to the Gulf of Mexico, the Suwannee River Basin
accounted for 4,485.1 tons of nitrate-nitrogen and 1,627.2 tons of total phosphorus. The
Middle Suwannee River Basin (Reach 3) covers 8.6% of the total Suwannee River Basin,
and accounted for 29.3% of the annual nitrate-nitrogen load delivered to the Gulf by the
Suwannee River. Reaches 5 and 6 of the Suwannee River covers 37.4% of the total
Suwannee River Basin, and contributed 34.7% of the annual nitrate-nitrogen load and
31.9% of the annual total phosphorus load delivered to the Gulf by the Suwannee River
(Table 4). Santa Fe River Reach 2 covers 5.7% of the total Suwannee River Basin, and
accounts for 19.6% of the annual nitrate-nitrogen load delivered to the Gulf by the
Suwannee River. Figure 4 provides a summary of relative nutrient loadings in the
Suwannee River Basin.
The data from Water Year (WY) 2002 showed a large increase in the relative contribution of
nitrate-nitrogen by the lower Suwannee reaches 5 and 6. Prior to WY2002, the District
estimated the nitrate-nitrogen loadings for the Suwannee River Basin by using the nitratenitrogen concentration observed at the water quality station SUW275C1, located in the
10
Suwannee River above the confluence with Gopher River (Suwannee River above Gopher
River) and the mean monthly discharge data collected at the U.S. Geological Survey
(USGS) gaging station (Suwannee River near Wilcox). The discharge gaging station
(Suwannee River near Wilcox) was the most downstream gaging station in the Suwannee
River from October 1930 to June 1999.
As part of the District’s Minimum Flows and Levels program, the District in cooperation with
the USGS in June 1999, installed a discharge gaging station in the Suwannee River above
Gopher River. After a calibration period (1999-2001) a flow rating was established and the
District began to use the discharge data to estimate the loadings for the Suwannee River
Basin in water year 2002. As a result of the new discharge data, the relative contributions of
nitrate-nitrogen loads from the sub-basins of the Suwannee River changed. This change
was due to an increase in discharge in the Suwannee River between the Wilcox gage (old)
and the Above Gopher River gage (new). This increase in discharge between the two
gages is due to previously unknown groundwater inputs into the river through the riverbed.
The USGS conducted an in-stream discharge monitoring in the fall of 2002. The results of
the in-stream monitoring are as follows:
Location
Suwannee River near Wilcox (old station)
Fanning Springs
Manatee Springs
Suwannee River at Old Town
Suwannee River at Fowler’s Bluff
Suwannee River above Gopher River (new station)
Discharge
2,200 cfs
62 cfs
102 cfs
2,180 cfs
3,050 cfs
4,550 cfs
The data shows a net increase in discharge in the Suwannee River between the old and
new gages of 2,350 cfs – a doubling. The change in loading is due to the previously
unaccounted ground water entering the Suwannee River between the old and new gaging
station containing similar nitrate-nitrogen concentration as the river.

Water Quality Ratings
Water quality conditions for each water body are qualitatively summarized with a rating of
good, fair, and poor, based on water chemistry conditions. A poor or fair rating does not
mean the water is unfit for human contact (swimming).
Based on the SRWMD water quality rating, sixteen water bodies, nine springs, and fourteen
lakes are rated Good (Table 5). Twelve water bodies, eight springs, and eight lakes are
rated Fair (Table 6). One water body, six springs, and six lakes are rated Poor (Table 7).
There were two streams and rivers for which the water quality ratings improved from 2002 to
2003. One spring improved in its water quality rating from 2002 to 2003.
Reaches 3, 4, 5, and 6 of the Suwannee River are impacted by increasing nutrients (i.e.,
nitrate-nitrogen) [Figure 4]. Also, Reach 2 of the Santa Fe River shows nutrient enrichment
similar to the Suwannee River (Figure 4).

Appendix A - Spring Survey
Twenty-two were monitored to assess groundwater effects on surfacewater quality. The
majority of the springs are discharging ground water with nitrate-nitrogen concentrations greater
than in the receiving water body. Spring discharges are typically above the background
concentration of 0.05 mg L-1 for ground water from the Floridan aquifer system (Groundwater
Quality Report 1997 [WR-98-02]). One spring had nitrate-nitrogen concentration in excess of the
primary drinking water standard of 10 mg L-1.
The relatively high concentrations of nitrate-nitrogen in the springs generally reflect the
concentrations observed in the District’s groundwater quality (Groundwater Quality Report 2003
[WR-03/04-02]).
The SRWMD environmental water quality (EWQ) rating is based on nitrate-nitrogen
concentrations. The ranges and ratings were taken from “Nitrate Occurrence in U.S. Water; A
Reference Summary of Published Sources from an Agricultural Perspective,” published by the
U.S. Department of Agriculture in 1991.

Appendix C. Biological Data
DEFINITIONS OF BIOLOGICAL METRICS
The data from the aquatic biological sampling are presented as various numeric scores, or metrics, which are quantitative
measures of the biological communities. An analogy to how these values describe biological “health” in surface waters is the
various indices (or metrics), which define the condition or health of the nation’s economy. The Dow Jones Industrial Average
and the Consumer Price Index are numeric measures by which the condition of the national economy is measured. In a similar
way, the biological metrics describe the status or health of the biological communities in our surface waters.
The metrics presented in this report are:
Benthic Invertebrate Taxa Richness - the total number of taxa (different kinds or species) of benthic invertebrates present.
Higher numbers mean more taxa present, which generally reflects a healthier benthic invertebrate community due to better
water quality and habitat conditions.
Benthic Invertebrate Diversity - an index which describes the composition of the benthic invertebrate community in terms of the
number of taxa present and the extent to which the community is dominated by few or many taxa. Higher numbers mean
higher diversity in the invertebrate community; meaning that the community is composed of an even mix of many different taxa.
Lower diversity means that fewer taxa are present or that the community is dominated by only one or a few taxa. Lower
diversity is generally indicative of some type of human disturbance or pollution.
Periphytic Algal Taxa Richness - the total number of taxa (particular kinds or species) of periphytic (attached to underwater
objects) algae present. Higher numbers mean more taxa present, generally indicative of better water quality.
