The MAP also presents the system-wide performance measures representative of the natural and human systems found in South Florida that will be evaluated to help determine the success of CERP. These system-wide performance measures address the responses of the South Florida ecosystem that the CERP is explicitly designed to improve, correct, or otherwise directly affect. A separate Performance Measure Documentation Report being prepared by RECOVER provides the scientific, technical, and legal basis for the performance measures. This project is intended to support the Greater Everglades (GE) Wetlands module of the MAP and is directly linked to the monitoring or supporting enhancement component
In 2003, CERP MAP funding through the South Florida Water Management District established 10 monitoring stations as part of the Coastal Gradients Network. The purpose of this MAP project with the USACE is to continue operation of these 10 stations for the MAP activities.

(1) Deliverable - Water level elevation referenced to the North American Datum of 1988 (NAVD'88) for all stations listed above.
(2) Timeframe - Surveys to be completed by September 30, 2004; elevation transfer to all reference marks to continue into FY-05 and completed in FY05.
Task 2 - Monitoring Station Operation and Maintenance This task includes: a) Operation and maintenance of field instrumentation, for the collection of water level, water velocity, salinity, and temperature data; b) Computation of discharge records (not at wetland sites); c) Quality assurance and quality control of all field and computed data; d) Data release and publication. USGS will service and maintain 10 monitoring stations in good working order and in a manner conducive to producing the data and deliverables identified in this SOW for the duration of the work order. The ten monitoring stations are as follows:
2a. Upstream Lostman's River- estuarine stream 2b. Upstream Broad River - estuarine stream 2c. Bottle Creek at Rookery Branch- estuarine stream 2d. Harney River- estuarine stream 2e. Upstream North River - estuarine stream 2f. Unnamed Creek near Manatee Bay- estuarine stream 2g. Unnamed Creek in Barnes Sound land - estuarine stream 2h. Southwest Taylor Slough northeast of Seven Palm Lake - upstream wetland 2i. Upstream eastern Joe Bay in the C-111 basin- upstream wetland 2j. Seven Palm Lake-lake
(1) Deliverable - A summary report on the status of all stations and data will be provided.
(2) Timeframe - The annual status summary report will be provided each September for fiscal years 2005, 2006 and 2007.
Task 3 - Salinity Surveys Salinity surveys will be performed using boat-mounted "flow-through" systems along the southwest coast of ENP, northeast coast of Florida Bay, and Manatee Bay/Barnes Sound areas. Data collected will include salinity, temperature, and GPS location for every data point. Four quarterly and two event-driven surveys will be completed on a yearly basis, totaling a maximum of six per year. These surveys will include the following river/creek systems:
3a. Lostman's river 3b. Broad River 3c. Shark/Harney River system 3d. North River/Whitewater Bay 3e. McCormick Creek/Seven Palm Lake 3f. Taylor River 3g. Trout Creek/Joe Bay 3h. Manatee Creek/Manatee Bay 3i. Barnes Sound Canal
(1) Deliverable - A summary report on salinity surveys will be provided.
(2) Timeframe - The annual summary report will be provided each September for fiscal years 2005, 2006 and 2007.
Task 4 - Water Quality Samples Water quality samples will be collected at three monitoring stations for determining the Total Nutrient concentrations (TN and TP). ISCO automatic samplers will be used for the collection of water quality samples at selected intervals. Point and cross-sectional samples will also be collected to determine "point-to-mean" relations and to quality assure ISCO samples. Locations for nutrient data collection are as follows:
4a. Upstream North River 4b. North River below Cutoff 4c.West Highway Creek
(1) Deliverable - A summary report of water quality information will be provided.
(2) Timeframe - The annual summary report will be provided each September for fiscal years 2005, 2006 and 2007.
Task 5 - Reports Annual reports are due at the end of each year and a final report is due approximately after the completion of the work order associated with this SOW. Annually, data for each year (ending September) will be processed, quality assured, and made publicly available by April of the following year.
c. Approach and Methodology in relation to Tasks 1 thru 4.
1. All water level information is referenced to local datum until NAVD-88 datum is established. NAVD-88 datum will be established using GPS static surveys at monitoring platforms.
2. All flow stations are instrumented with water level, salinity, temperature and velocity sensors. Velocity data will be collected with acoustic Doppler instruments, calibrated with the use of an Acoustic Doppler Current Profiler (ADCP), and used in the computation of discharge. Monthly ADCP discharge measurements will be done at all new sites during the first year and bi-monthly thereafter for rating verification purposes. Salinity and temperature data will be collected at one or two depths in the water column.
3. Discharge data is computed using established area and velocity ratings. Area ratings are developed using depth soundings from available ADCP measurements at each site and OSW supported software programs. Index-velocity ratings will be developed through regression analyses, determining relations between instrument velocity (Index velocity) and mean cross-sectional velocity from ADCP measurements.
4. Marsh sites are instrumented with water level, salinity, temperature, and velocity sensors. Velocity data will be recorded with acoustic Doppler instruments. Salinity and temperature will be recorded at one or two depths in the water column. No discharge will be computed for these sites.
5. Water velocity in the marshes is quality-assured and will be made available. No discharge will be computed at these locations.
6. Groundwater wells are instrumented with water level, salinity, and temperature sensors. Pressure transducers are used to measure water level at ground water wells.
7. Salinity and temperature probes are cleaned and calibrated on a monthly basis to assure the quality of record.
8. Salinity surveys are performed using boat-mounted flow-through systems equipped with a salinity/temperature sensor and a Global Positioning System (GPS).
9. ISCO automatic samplers are used at three locations to collect water samples for Nutrient analysis. Every 18 hours water is pumped and a composite bottle is made up of 3 pumping sessions.
10. Field visits to collect sample bottles are made on a 3-week schedule.
11. During site visits, grab samples are taken and analyzed for total and dissolved nutrients.
12. Water samples collected with auto-samplers are analyzed for total nitrogen (TN) and total phosphorus (TP) concentrations.
13. Grab samples are analyzed for total and dissolved nutrients, and used to compliment and quality assured auto-sampler data.
Salinity surveys will be performed using boat-mounted systems to collect information along the southwestern coast of ENP, northeastern coast of Florida Bay, and Manatee Bay/Barnes Sound. The information will include salinity and temperature data and geographic location in latitude and longitude for every data point. Four quarterly and two event-driven surveys will be completed on a yearly basis for a maximum of six per year. The salinity survey is performed on the same day across the study area and usually requires the use of 4 boats and 8 crew members to complete. The surveys will include these river/creek systems: Lostmans River to upstream Lostmans River; Broad River to upstream Broad River; Shark River/Harney River to Bottle Creek; North River to upstream North River; McCormick Creek to Seven Palm Lake; Taylor River mouth to upstream Taylor River; Trout Creek to Joe Bay/Snag Bay; and Barnes Sound to Manatee Bay/Card Sound Canal.
Salinity surveys are performed using boat-mounted flow-through systems equipped with a YSI water quality monitor for collection of temperature and salinity. Position is determined using a GPS unit which interfaces with the YSI water quality monitor. Data collection occurs every 5 seconds and is stored in the YSI 650 data acquisition system. The accuracy of all instrumentation is verified in the USGS Ft. Lauderdale laboratory or in the field before and after the salinity survey. The temperature probe is verified using a digital NIST thermometer in the Ft. Lauderdale lab. Data collected from the four boats is combined in a spreadsheet and analyzed for erroneous data such as spikes and 0.0 values. Salinity data is then imported into a GIS package for map creation. Raw data and spatial maps will be posted on SOFIA or published in the final USGS Data Series Report to be published in 2010.
