Overview & Objectives:
Proposed modified water deliveries to Indian Tribal Lands, Big Cypress National Preserve, and Water Conservation Area 3A require monitoring of flows and nutrient loads at critical points of the interior surface water network within the Greater Everglades. Defining the foundation for water levels, flows, and nutrient loads has become an important baseline for Storm Treatment Area 5 and 6 development, recent C-139 Basin flow re-diversions, and future L-28 Interceptor Canal de-compartmentalization including flow rerouting into the Big Cypress Preserve. Flow monitoring for the two primary flow routes for both L-28 Interceptor Canal and L-28, exiting the southern boundary of the Seminole Big Cypress Reservation, is key to developing this framework. Additional flow monitoring of canals entering the Reservation has begun and been proposed; North Feeder monitoring began in FY 2011, and another monitoring station at West Feeder has been proposed.
Specific Relevance to Major Unanswered Questions and
Information Needs Identified:
Flow and total phosphorus budget summaries are critical to the newer non-point source EPA guidelines and in turn are integral to several of the Comprehensive Everglades Restoration Project (CERP) planning objectives which rely heavily on Total Maximum Daily Loads (TMDL) calculations. Analysis of Storm Treatment Area and Best Management Practice outcomes can only be evaluated through baseline data monitoring efforts. These data sets will define parameters for de-compartmentalization and Tribal Reservation flow re-routing initiatives currently under evaluation.
The study supports Water Conservation Area 3 Decompartmentalization and Sheetflow Enhancement by monitoring the canal inflow and nutrient totals exiting the Seminole Reservation from the West and North Feeder Canals, and the headwaters of the L-3, L-4, and L-28 canal intersections. Flow and nutrient load products from both L-28 Interceptor and L-28 Canals eventually discharge into Conservation Area 3A. Baseline quantification of flow and nutrient totals are critical for defining the success of recent Best Management Nutrient load reduction initiatives for the L-28 and L-28 Interceptor Canals. Proposed backfilling of the L-28 Interceptor Canal and subsequent re-diversion of flows from Conservation Area 3A and into the Big Cypress Preserve is an important baseline prerequisite prior to flow reapportionment outside the current 3A boundaries.
The study supports Comprehensive Integrated Water Quality Feasibility Study by developing water quality targets for ecosystem restoration. The success of Best Management Practices along with the implementation of Storm Treatment Areas (STA) 5 and 6 can be evaluated based on the baseline total phosphorus load totals resulting from these two critically monitored conservation area inflow points.
Finally this study supports the Ecosystem Restoration mission delineated in the Five Year Science Plan for the Florida Water Science Center.
Provisional analysis and computation of 2011 water year flows continues along with acoustic flow rating calibration and auto-sampler servicing by Seminole Tribe water resource staff for both flow-weighted acoustic auto-sampler sites. A side-looking acoustic Doppler system is used to compute flows by the index velocity method. Pre-publication data sets continue to be transferred to SFWMD support staff for nutrient load computation and inclusion in the reports for the Seminole Tribe Working Group.

Title of Task 1: Rating calibration, analysis, processing, and publication
of stage and discharge data at 2 primary flow-way sites.
Task Funding: USGS Greater Everglades Priority Ecosystems Science (GE PES); the Seminole Tribe of Florida
Task Leaders: Mark Dickman
Task Status (proposed or active): active
Task Priority: high
Time Frame for Task 1: FY12: October 1, 2011 to September 30, 2012.
Task Personnel: Rick Solis, Corey Whittaker, Eric Carlson
Task Summary and Objectives: Continue velocity rating refinement and calibration of the side-looking Doppler acoustic systems located at the L-28IN, L-28U, and North Feeder sites, and prepare for installation of an additional monitoring station at the West Feeder site. All stations include instrumentation for telemetry of the data to NWISWeb for public release and programmed to operate an Auto-sampler at each site. The objectives of this task are to monitor tele-metered velocities and channel area so real-time Auto-sampler flow-weighted nutrient load volume triggers are maintained. Provisional discharges will continue to be analyzed, processed and forwarded to the Seminole/SFWMD Working Group. Final quality assured water-level and flow to be published annually in the publication, Water-Data Report 2012.
Work to be undertaken during the
proposal year and a description of the methods and procedures:
- Continue calibration and refinement of the Side-looking Doppler acoustic velocity index ratings utilizing the Acoustic Doppler Current Profiler (ADCP). Requests to the SFWMD control room will be submitted to vary pump rpm at the S-140 pump structure and to regulate the S-190 gate structures in attempts to achieve variable velocity regimes at each station.
- Provisional analysis and computation of provisional flows will be provided to the Seminole/SFWMD Working group for inclusion in the Fourteenth and Fifteenth semi-annual Data Progress Reports produced periodically by SFWMD staff. Data quality assurance reviews will continue throughout each water year culminating in the publication of daily mean water levels and discharge for these sites in the USGS report entitled, Water-Data Report 2011. NWISWeb provides provisional real-time data and approved daily value. Efforts to provide information to appropriate electronic outlets (e.g. SOFIA site) will continue.
- As an extension of the program, an additional monitoring station will be installed at the West Feeder canal to monitor the inflows into the Reservation. This proposed station will also have telemetry to transmit the data to NWIS and for release on NWISWeb.
Specific Task Products(s): Provisional semi-annual daily stage and discharge computations will be made available in May and November 2011 for inclusion in the "Fifteenth Progress Report for May 1, 2010 through April 30, 2011." Daily stage and discharge will be made available through September 2012 and published in the "Water-Data Report 2012" and NWISWeb. Real-time data will be provisionally available on NWISWeb.
