Section 1.0 Introduction The Santa Fe River is classified as an Outstanding Florida Water and is home to over 40 recorded springs. The river and springs provide essential habitat for a diversity of flora and fauna and are a major contributor to the economic vitality of surrounding areas (FSI 2012, SRWMD 2014)). However, the Santa Fe River and springs are experiencing negative impacts from a variety of stressors including reduced discharge, increased nitrate-nitrogen levels, excessive recreation, harmful aquatic plant management activities, and structural alterations. These changes are resulting in a shifting ecological baseline for the Santa Fe river.
The Howard T. Odum Florida Springs Institute (FSI) in partnership with Our Santa Fe River, Inc. (OSFR) and other collaborators (Table 1) is conducting a Santa Fe River and Springs Environmental Analysis. The project consists of 3 phases; Phase 1 - a summary of existing data (completed in May 2017 [FSI 2017]), Phase 2 - a detailed river health evaluation, and Phase 3 - the development of a holistic management plan and recovery strategy. This report is a Phase 2 interim deliverable.
FSI began data collection at Santa Fe River springs, spring runs, and river stations (Figure 1) for Phase 2 in April 2018. The aim of this phase is to fill existing data gaps by conducting a comprehensive, two-year monitoring program to improve understanding of the physical, chemical, biological, and ecological condition of the springs and river. These data will be used in conjunction with other existing and ongoing research to develop an updated baseline of ecological conditions for the Santa Fe River and springs that can be used to assess ongoing changes in spring and river health and serve as a basis for developing a recovery and management strategy.
Results from the first four quarters of sampling (April 2018 through March 2019) were summarized previously (FSI 2019). This report summarizes progress through the first fifteen months of intensive sampling (April 2018 through June 2019). Detailed data for the fifth quarter (April- June 2019) can be found in Appendix C.

Section 2.0 Methods 2.1 Introduction Data were collected over a 15-month period along the Santa Fe River as well as from several of its springs, and 3 of its major tributaries: the Ichetucknee River, Olustee Creek, and Cow Creek. For this assessment, monitoring was divided into five study segments, with one segment within the Upper Santa Fe River from SR 121 bridge at Worthington Springs downstream to O’Leno State Park, three segments within the Lower Santa Fe River below River Rise, and two tributary segments (Olustee Creek and Ichetucknee River):
• Upper Santa Fe River o Segment 1 (Worthington Spring at SR 121 to the Santa Fe River Sink in O’Leno
State Park) • Lower Santa Fe River
o Segment 2 (Santa Fe River Rise to US Hwy 27) o Segment 3 (US Hwy 27 to State Road 47) o Segment 4 (State Road 47 to Suwannee River confluence)
• Olustee Creek (CR 18 bridge to Santa Fe River confluence) • Ichetucknee River (Head Spring to Santa Fe River confluence)
Routine monitoring of water quality field parameters, nitrate nitrogen and color, and physical conditions was conducted in each segment during Quarters 1-5 (April 2018 through June 2019). Table 2 provides sampling frequencies for spring, spring run, and river stations. Detailed maps identifying monitoring station locations for each segment are provided in Figure 2 through Figure 4. A total of 61 monitoring stations were selected to characterize water quality and related ecological conditions. Additional ecological and biological data were collected at three spring and river sites during the quarter. The ecological and biological surveys include recording data sonde and HOBO (temperature and light pendant) deployments, fish counts, vegetation surveys and flow measurements. These representative sites included:
• Poe Springs • Gilchrist Blue/Naked Springs • Ichetucknee River/Blue Hole Spring
Water quality samples were collected for analysis by the Florida Department of Environmental Protection (FDEP) analytical laboratory for color, chloride, sulfate, arsenic, copper, iron, chlorophyll a, nitrate+nitrite nitrogen, total ammonia, total Kjeldahl nitrogen, total phosphorus, and fecal coliforms at 10 river and 20 spring sites on a quarterly basis, with 10 sites sampled each month. Priority herbicides and insecticides were tested at 10 spring or river stations quarterly. During routine monitoring, water samples were also collected for analysis by McGlynn Laboratories Inc. for nitrate nitrogen and color.

2.2 Physical Environment 2.2.1 Underwater Light Transmission Photosynthetically Active Radiation (PAR), underwater light transmission, and attenuation coefficients were measured monthly at 56 of the 61 monitoring sites during comprehensive ecological assessments and while collecting monthly samples for laboratory analysis. Data were collected using a LI-COR brand LI-192 underwater quantum sensor to measure PAR energy reaching the water surface and at 1-foot intervals from the surface to the bottom of the water column. Figure 5 provides a typical light senor installation. Light extinction (attenuation) coefficients were calculated from these data using the Lambert-Beer equation (Wetzel 2001):
Iz = Io(e-kz)
Where:
Iz = PAR at depth z
Io = PAR at the water surface
k = diffuse attenuation coefficient, m-1
z = water depth, m

2.2.2 Water Quality Field parameters (water temperature, dissolved oxygen concentration, oxygen percent saturation, pH, and specific conductance) were measured monthly using a YSI proDSS meter at each of the 61 (28 river and 33 springs) monitoring sites, during comprehensive ecological assessments, and while collecting monthly samples for laboratory analysis.
During routine monitoring, water samples were collected at 60 of the 61 sample sites and sent to McGlynn Laboratories Inc. for nitrate nitrogen and color analysis. Samples were collected by placing a capped sample bottle below the surface water, uncapping to collect water, and recapping underwater. Samples have a 28-day holding time and are sent to the lab bi-weekly.
Water samples for laboratory analysis were also collected according to Department of Environmental Protection (FDEP) standard operating procedures. Thirty sites (10 river and 20 springs) were sampled four times throughout the year. Samples were shipped overnight to the FDEP Central Laboratory in Tallahassee where they were analyzed for color, chloride, sulfate, arsenic, copper, iron, chlorophyll a, NOx-N, NH4-N, TKN, total phosphorus, and fecal coliforms. Ten spring and river sites were also sampled once per quarter for additional priority herbicides, insecticides, and trace organic compounds.
2.2.3 Secchi Disk Visibility Visual water clarity was assessed using Secchi disk visibility, the distance where a standard white and black Secchi disk disappears. At tannic river and creek stations, the Secchi depth was estimated by vertically lowering the Secchi disk below the water surface. In spring systems, underwater visibility is commonly greater than the depth of the water column, in those cases Secchi disk visibility was measured horizontally. Vertical and horizontal Secchi distance was measured with a 20-centimeter diameter black and white disk attached to the end of a tape measure below the surface of the water. For horizontal readings a skin diver extended the tape while moving away from the disk and recorded the distance at which it was no longer visible. Secchi disk measurements were taken at 39 stations during monthly monitoring sessions and during comprehensive ecological sampling.
2.2.4 Stream Discharge Stream discharge was measured at 13 locations, including 10 springs, at the US-27 bridge, Ichetucknee below the Blue Hole confluence, and at the mouth of the Ichetucknee River (LIR-15) using a Hach FH950 portable velocity meter. At each location, a fiberglass tape was stretched across the stream channel perpendicular to the flow direction, allowing depth and velocity to be measured in up to 25 evenly spaced segments. Narrower streams were measured at 10-22 segments. At water depths less than 2.5 ft, velocity was measured at 0.6 of the water column depth. For water depths greater than 2.5 ft, velocity was measured at 0.2, 0.6, and 0.8 fractional depths of the water column.

2.3 Biology 2.3.1 Fish Visual surveys of the fish communities were conducted during ecological assessments at the Ichetucknee Headspring and run, as well as, Blue Hole, Gilchrist Blue, Naked, and Poe springs systems. Visual surveys of fish communities were made by 2 to 3 people using mask and snorkel gear. Observers spread out to evenly span the spring run segment and swam in parallel paths, noting the fish species or groups of similar species (lowest practical taxonomic level) of all observed fish. All observations were reported to a data recorder, who was at a fixed location on shore or who followed the observers in a boat. Following each survey, observers estimated the total length (average and range) by fish species. Fish density was calculated for each sub-section by dividing the number of individual fishes counted by the area sampled. Wet-weight biomass of fish species was estimated using published length-weight relationships (Schneider et al. 2000) and average species total lengths and total numbers. Fish assemblage diversity was calculated using the Shannon-Wiener diversity index based on the calculated densities of individual species or groups (Zar 1984).
2.3.2 Plant Community Characterization The distribution and percent cover of aquatic plant communities (macroalgae and submerged aquatic vegetation), as well as substrates in the study segment were visually estimated this quarter in 3 spring systems: Gilchrist Blue Springs, Poe and the Ichetucknee River. Aquatic vegetative cover was documented along several transects in each spring run using the line-intercept method. A tape measure was stretched along each transect, and all aquatic plant communities intercepting the vertical plane of the line were recorded. Line-intercept data were used to estimate percent cover, frequency, relative cover, and relative frequency. Frequency was based on dividing each transect into 8 equal sized sub-transects. Values by species were summed and averaged to yield an importance value as follows:
Linear Cover Distance for Species A =∑ (m)A Speciesfor distancesintercept line

2.3.3 Human Use Human use is a physical factor that has potential to impact springs. Foot traffic in the spring and its run and bank erosion are two common ways that humans can influence the health of a spring. Many springs with shallow runs experience plant disturbance when visitors can walk in the run. Human use was recorded at the Gilchrist Blue, Ichetucknee and Poe springs systems. During ecological monitoring, human use was monitored at one location for the duration of ecological sampling and compared to observations from a weekend day. Observers recorded the number of individuals participating in in-water and out-of-water activities in 15-minute intervals. In-water categories include wading, bathing, swimming, snorkeling, tubing, canoeing/kayaking, fishing and “other” and out-of-water categories include sitting, walking, sunbathing, nature study, dive prep and “other”. Figure 6 through Figure 10 show the study area for all springs for human use observations.
Results from human use surveys are provided in section 3.2.3 Human Use.

Section 3.0 Results This section summarizes data collected as part of the ecosystem monitoring conducted along the Santa Fe River and springs from Quarters 1 through 5 (April 2018 through June 2019). These data provide a quantitative record of existing conditions in the river and are useful for comparison to historic and future environmental data from the Santa Fe River and springs. Parameter figures are represented by a box and whisker plot. River stations are indicated with a green diamond and spring stations with a blue diamond
3.1 Physical Environment 3.1.1 Underwater Light Transmission The summaries of PAR percent transmittance and diffuse attenuation data collected on the Santa Fe and Ichetucknee river are presented in Figure 12 and Figure 13. PAR diffuse attenuation is consistently highest in the tannic waters of the Upper Santa Fe, and lowest in the springs. Light transmittance is consistently higher in the spring and spring run stations and increases in the Santa Fe River with travel distance downstream until reaching segment 4 (SFR at SR-47). PAR attenuation in the Ichetucknee River (dominated by spring flow) is typically less than 1 and transmittance is typically greater than 50%, like the Santa Fe River springs.
3.1.9 Water Clarity Figure 14 and Figure 15 present the average horizontal and vertical Secchi disc readings at sites on the Santa Fe and the Ichetucknee Rivers. Spring stations typically had readings greater than 15m except for vertical Secchi readings in Segment 2 at Santa Fe Spring. Santa Fe River stations had Secchi readings that were typically below 3m. Horizontal Secchi readings were between 8.5 and 52m. Of the springs studied, Gilchrist Blue Spring had the highest measured water clarity with an average visibility of 52 m. Little Devil and Ginnie Springs also had good clarity averaging 49 m and 48 m, respectively.
3.1.2 Water Quality Figure 16 shows the water quality results for samples collected by FSI staff on four segments of the Santa Fe River and associated springs, and the Ichetucknee River and associated springs. Compared to the adjacent river stations, spring stations have lower dissolved oxygen concentrations and higher specific conductance. pH shows a similar fluctuation between spring and river stations, with river stations being slightly more acidic due to the influence of rain, whereas river temperatures spike during the 2nd quarter (summer months) and drop again in the fall and winter months. During quarter 5, the average temperature continues to drop, which may be due to the lack of rainfall/runoff, and therefore greater influence of spring water in the river.
3.1.3 Dissolved Oxygen Figure 17 presents boxplots to display the fluctuation of dissolved oxygen (mg/L) measured along four segments of the Santa Fe River as well as the Ichetucknee River between 1 April 2018 and 30 June 2019. During this sampling period, the Santa Fe River dissolved oxygen concentrations were typically 4 mg/L or higher while spring stations had variable DO values ranging from very low (0.38 mg/L at Hornsby Spring) to over 5 mg/L at the Gilchrist Blue Springs Group. The Ichetucknee Head Spring as well as Cedar Head Spring Run and Blue Hole spring feeding the Ichetucknee River have lower DO concentrations (<4.4 mg/L) while the DO concentrations in the main channel of the Ichetucknee River rise from about 4 mg/L at the upstream canoe launch to over 6.75 mg/L near the tube takeout location.

3.1.4 pH Figure 18 presents boxplots to display the fluctuation of pH measured along four segments of the Santa Fe River and the Ichetucknee River between 1 April 2018 and 30 June 2019. pH values in segments one and two had values below 7.2 s.u. due to a lack of spring water and influence of rainwater and runoff. Hornsby Spring (segment 2) has a higher pH at 7.42 s.u. which is more representative of the groundwater feeding the springs. All river and spring stations downstream from US-27 had values between 7.25 and 7.40 s.u with little variation between spring and river stations until segment 4 where the water is slightly more basic.
3.1.5 Specific Conductance Figure 19 presents boxplots to display the fluctuation of specific conductance measured along four segments of the Santa Fe River and the Ichetucknee River between 1 April 2018 and 30 June 2019. Spring stations typically had a higher specific conductance value compared to the river stations and did not vary as much. Specific conductance is a useful parameter when determining how much groundwater is entering the river and its origin. Changes in conductivity measurements may be related to the mixing of groundwater with surface water, rain or other inputs. River stations varied more, due to rain occurrences, dry periods, and runoff. During periods of high rainfall, the conductance is lower, but in times of little rainfall, the river is mainly spring fed, thus increasing the specific conductance. Santa Fe Spring in segment 1 had an average of 285 umhos/cm, while most other springs in other segments had specific conductance values between 295 and 456 umhos/cm. Lower specific conductance values in springs are likely associated with periodic flow reversals and subsequent discharge of groundwater with a significant surface water component. Troop spring had an unusually high average specific conductance of 870 umhos/cm as well as neighboring springs such as Betty Spring, and Trail Spring (~450 umhos/cm). These three springs are located 1-2 miles North of Alliance Branford Dairy (American Dairy), and have high concentrations of NOx-N, indicating the influence of wastewater input into the groundwater coming out of these springs.
3.1.6 Water Temperature Figure 20 presents boxplots to display the fluctuation of water temperature (°C) measurements along four segments of the Santa Fe River and along the Ichetucknee River collected between 1 April and 30 June 2019. River stations show more variability whereas springs have a consistent average of 21.8-22.9°C except for Santa Fe Spring at an average of 20.93°C. The depth of the river changes greatly throughout the year, allowing surface waters to warm when levels are lower, but increased rainfall and winter months cool the water, producing the wider range on the boxplots.
3.1.7 Discharge Figure 21 presents boxplots of discharge measurements collected for nine spring and two river stations along portions of the Santa Fe River and Ichetucknee River collected between 01 April and 30 June 2019. Santa Fe Spring and Hornsby Spring show the greatest variation where they increase in flow during the wetter months and decrease in flow during dry months. The remaining springs and Ichetucknee River stations show little to no fluctuation throughout the seasons.

Santa Fe River and Springs Quarterly Report (April 2018 –June 2019)

3.1.9 Flow and Nitrate Period of Record Figure 22 illustrates spring and river flows and nitrate concentrations used to estimate the tons of NOx-N at key measurement stations along the Santa Fe River. These numbers were based on the discharge measurements and reported NOx-N concentrations observed during quarter 5 only (April-June 2019). During this quarterly monitoring period, the estimated nitrate nitrogen load increased dramatically with distance down river, from an average of 13.4 tons/year in the Santa Fe River at the Worthington Springs station, to an average of 1682 tons/year in the Santa Fe River at U.S. 129, upstream of the confluence with the Suwannee River. This is an observed net increase of 1,669 tons of nitrogen per year entering the Suwannee River. Flows and concentrations at key stations were combined to estimate loads per time at spring and river stations. Flow data for the period of record are recorded by FSI staff, Suwannee River Water Management District (SRWMD), and the U.S. Geological Survey (USGS). Nitrate nitrogen data is collected by FSI staff and analyzed by FDEP and McGlynn Laboratories Inc. Measured nitrogen inputs are represented by blue circles and boxes. Measured flows are multiplied by nitrate-N concentrations to estimate average mass of nitrogen (tons per year) entering the Santa Fe River. Estimated inputs are in green and are calculated by taking the difference between measured upstream and downstream nitrogen loads. Estimated nitrogen loads at some stations such as SFR at US-27 and SFR at US-441 are based on FSI’s measured or estimated flows. SFR at US-27 flow was measured monthly by FSI staff, and SFR at US-441 flow was estimated by creating a stage-discharge curve that was produced by using manually read stage and flow measurements reported by SRWMD. As additional data are collected, discharge estimates at this station will be more reliable.
Flow rates at river stations increased from upstream to downstream from 45 cfs to 1,857 cfs. This increase is due to a combination of surface water inputs from Olustee and Cow Creeks and increasing groundwater inputs from upstream to downstream. In terms of total nitrogen inputs to the river of 1,682 tons, less than 4% entered as surface water inflows, 96% was derived from spring and diffuse groundwater inflows. The difference between the Santa Fe River nitrogen mass inputs and mass outflow to the Suwannee River indicated that in-stream nitrate nitrogen assimilation/dissimilation by chemical and biological processes was negligible.
Figure 23 presents the average nitrate-and-nitrite (NOx-N) levels measured at 50 locations along the Santa Fe River and 11 locations along the Ichetucknee. Segments 1 and 2 (SFR at Worthington Spring to COL930971) had values that were typically lower than the springs numeric nutrient standard of 0.35 mg/L, except for all springs stations in those segments, which ranged from 0.47 to 0.72 mg/L. NOx-N concentrations were generally highest in the spring boils, with the Gilchrist blue Spring Group having values typically above 2 mg/L, Ginnie Spring system ranging from 1.42 to 2.02 mg/L and Betty/Troop/Trail springs with very high concentrations ranging from 5 mg/L to more than 50 mg/L. Elevated NOx-N concentrations at Betty, Troop, and Trail springs may be attributed to their proximity to Alliance Dairy located only 1-2 miles to the south. The numeric nutrient limit for nitrate of 0.35 mg/L set by the Florida Department of Environmental Protection is represented by a grey dotted line on the graph.

3.1.8 Detailed Water Chemistry Appendix A presents the results of water chemistry analysis of samples collected at 10 sites along the Santa Fe River and at 20 of its springs and tributaries. Samples collected were also analyzed for 71 priority herbicides, pesticides, and trace organic compounds. Table 3 presents average analyte detection results for the Santa Fe River and its springs. Boxes highlighted in blue present a value below the detection limit. These values were calculated by averaging all spring and all river values for the period of record.

3.2 Biology 3.2.1 Fish Table 4 presents the results from seasonal data from fish counts during ecological and biological monitoring in seven Santa Fe River and Ichetucknee River springs. Overall, when comparing fish biomass in the presented springs and rivers, quarters 2 and 3 (July-Sept and Oct-Dec) typically had the lowest biomass. Quarters 1, 4 and 5 had higher biomass values. During the April-June (Q1 and Q5) fish surveys, many juvenile fish were counted after spawning events occurred. Quarter 5 had counts in the thousands which may be due to the spawning events, as well as increased experience in the research team conducting the counts.
Figure 24 illustrates the changes in biomass in each system throughout the year.
Detailed fish data for quarters 1-5 can be found in Appendix B.

3.2.2 Vegetation Figure 25 through Figure 29 present the results of vegetation surveys conducted along transects at Gilchrist Blue, Naked, Blue Hole, Poe springs as well as a portion of the Ichetucknee River. Observations have been divided into six categories: detritus, bare ground (sand, rocks, roots, etc.), algae, submerged aquatic vegetation (SAV), emergent vegetation, and floating vegetation.
Figure 25 illustrates the vegetation shift observed in Gilchrist Blue Spring from April to June. The algae cover decreased from 30% in April to 11.8% in June, with detritus increasing from to 15% in April to 32% in June. With SAV ranging from only 12.7 to 15.8%, algae, bare ground and detritus dominate the system.
Naked Spring (Figure 26) is heavily dominated by detritus. The algae cover has ranged between 11 and 23%. During quarters 3 and 4, Naked experienced heavy rain and downed trees due to storms. The detritus build-up is most likely due to submerged trees lying within the spring for an extended period. The algae cover may have decreased from 23 to 11% due to the removal of the mentioned trees, and disturbance of the spring bottom during the work.
Figure 27 illustrates the shift of percent cover in the Ichetucknee Head Spring and its run to below the confluence of Blue Hole Spring. The presence of bare ground, detritus and floating vegetation (duckweed) remains constant throughout May and June, and we see an increase in SAV and decrease in algae. As rainfall increased, the run became deeper as water levels rose, thus reducing the amount of foot traffic in the spring run. SAV had the chance to begin recovering from the disturbances. Percent cover in Blue Hole Spring (Figure 28) consisted mostly of SAV, algae, and floating vegetation (duckweed). Due to the depth and high discharge of the spring, foot traffic is not common, possibly contributing to the relatively high cover of strap-leaf sagittaria. The observed algal cover in Blue Hole is primarily epiphytic with excessive growth covering much of the native SAV.
Poe Spring (Figure 29) is biologically depauperate. Although nitrates are low, emergent, submerged and floating vegetation were not recorded during this study period. The proportions of bare ground, detritus and algae changed very little from May to June.

3.2.3 Human Use Figure 30 through Figure 41 illustrate weekday and weekend comparisons of human use of three major springs systems. Each figure contains a graph comparing in water vs out of water activity at each 15-minute interval as well as two detailed graphs specifying the specific activities taking place in and out of water.
Gilchrist Blue Spring was monitored twice during the week (Figure 30 and Figure 32) and once during the weekend (Figure 31). During the weekday monitoring, the maximum number of guests ranged from 60-75 while the Sunday survey had more than 300 guests enjoying the state park. During the weekdays, more out of water activity activities were taking place with most park guests sitting and walking along the spring. As for weekday in water activities, guests were mostly wading or swimming. Weekend use was evenly split between in water and out of water activities. Throughout the day, most guests were wading, sitting or walking.
Naked Spring was monitored during May and June. During the weekday survey (Figure 33) the maximum number of people in or near the spring was 7, while the weekend survey (Figure 34) recorded over 30 people. The Naked Spring survey area is approximately 0.064 hectares (98% smaller than the Gilchrist blue Spring system), so fewer people are expected to be at the spring. During the weekday survey, in water activities were observed for just over an hour. Out of water activities were observed throughout the 3 hours and 45 minutes, with most people walking to and along the spring. During the weekend, more people were observed in the water mostly wading, bathing and tubing.
Ichetucknee Head Spring human use data was collected in May and June. During the weekday survey (Figure 35) a maximum of just over 30 people were observed in or around the spring during a 15 minute interval, while the weekend surveyor counted more than 125 people utilizing the spring at a given time (Figure 36). For both days, an increase in guests began as late as 12:30. During the weekend, ~70% of people were observed in the water wading, bathing and swimming,
Blue Hole Spring was surveyed in May and June. During the weekday survey (Figure 37) a maximum of 15 people were observed during a survey interval, while the weekend survey Figure 38) had almost 45 people in or around the spring. During the Wednesday survey, in water activity was observed for only one hour of the five-hour survey with only wading, swimming, snorkeling, and kayak/canoeing occurring. As for the out of water activity, mostly the FSI science team and fellow nature observers were recorded around the spring. During the weekend, out of water activity was most observed with most people walking to or from the spring.
Poe Spring was surveyed during two weekdays (Figure 39 and Figure 40) and one weekend day (Figure 41). During the weekdays, human use maxed out at 23-44 people in/around the spring, while during the weekend almost 200 people were at/in the spring. During the weekend, in water and out of water use was split 50/50 with most people wading, sitting and walking. Gilchrist Blue Spring had only 100 more people during its weekend survey which is surprising due to the popularity and size of the human use area.
