Study Title: Analysis of Historical Water-Quality Data (Phase 1) / Integration, and Synthesis of Water Quality and Flow Data for Assessing Nutrient Flux to South Florida Coastal Ecosystems (Phase 2)
Overview & Objective(s): The study provides a review and analysis of historical water-quality data in BCNP, ENP, and LNWR (Phase 1) and nearby coastal waters of south Florida (Phase 2). This information will help establish water-quality standards and baseline conditions in the parks, and will help evaluate the potential effects of CERP on water quality. Objectives of Phase 1 include: (1) assemble, review and edit water-quality data and provide a working data base; (2) analyze and evaluate the data and prepare interpretative reports on historical water-quality conditions and trends in BCNP, ENP, LNWR, and DOI coastal waters. These analyses will provide a baseline for evaluating how CERP might affect water quality in the parks and refuge.
Phase 2 - Documentation of coastal nutrient loads prior to CERP implementation is important to evaluate the impact of increasing freshwater flows to Florida Bay and the southwest coast. Although nutrient data is currently being collected by the USGS and by the Florida International University (FIU) Long-Term Ecosystem (LTER) program from several tidal creeks along the costal region of the Everglades National Park, this network has yet to produce nutrient loads into Florida Bay and the southwest coast. The scope and objectives of Phase 2 are to: (1) Compile and summarize data that have been collected by different agencies and universities on water flow and water quality in tidal creeks and rivers that flow into coastal waters of ENP. (2) Compile flow and nutrient data from two river index systems (Trout Creek and Shark River)that could be used to estimate annual and monthly nutrient flux. (3) Compile and synthesize information on freshwater and nutrient fluxes to the coastal waters of ENP.

Specific Relevance to Information Needs Identified in DOI's Science Plan in Support of Ecosystem Restoration, Preservation, and Protection in South Florida (DOI's Everglades Science Plan) [Page numbers listed below are from the DOI Everglades Science Plan. The Science Plan is posted on SOFIA's Web site: http://sofia.usgs.gov/publications/reports/doi-science-plan/]:
This study supports several of the projects listed in the DOI science plan. These projects include: (1) Arthur R. Marshall L NWR Internal Canal Structure (p. 37). The study provides data and analysis of historic hydrologic and water-quality conditions in the Loxahatchee refuge (p. 40) needed to develop the specific hydrologic and ecological targets for the project. (2) Water Conservation Area 3 Decompartmentalization and Sheetflow Enhancement (p. 66), and (3) Additional Water for Everglades National Park and Biscayne Bay Feasibility Study (p. 73). The study provides data and analysis of historical hydrologic, land use and water management changes, and water-quality conditions in BCNP, ENP and LNWR. These data and analyses complement hydrologic, paleoecological, and modeling investigations in these DOI lands, provide better understanding of linkages between geologic, hydrologic, chemical and biological processes in the Everglades (pages 68 and 74), and support in the development of hydrologic targets for the restoration projects.
