(The purpose of the base programs analysis is to recognize the current public and private environmental regulatory programs, provide an assessment of the overall programs that are in place, and identify the gaps in the existing institutional framework for resource management.  Provides a snapshot of the Charlotte Harbor National Estuary Program's socioeconomic conditions.  It reviews the current institutional management of the natural resources in the greater Charlotte Harbor watershed.  This analysis is performed within an outline of the three major priority problems: hydrologic alterations; water quality degradation; and fish and wildlife habitat loss.)

(The report discusses land use, water use, streamflow, and river water quality in the Charlotte Harbor inflow area.  Previously published studies were reviewed.  Graphical techniques and statistical procedures were used to evaluate and interpret the data.  The compilation and analyses of data are based on the following time frames: land use (1972-73 and 1984); water use (1975 and 1980); streamflow (through 1984); and water quality (through 1985).)

(The purpose of the report was to describe the occurrence and quality of surface and ground water in the Myakka River Basin area, to report the amount of ground water used as of 1965, and to define current and potential water-resources problems.  The major emphasis is on ground-water resources.  Stage and discharge records from 54 streamflow stations and records of about 400 wells were collected during 1963-66.  The well data include records of water levels, discharge, well construction, and driller and geophysical logs.  21 test wells were drilled as part of the investigation in cooperation with Sarasota County.  Water samples were collected for chemical analysis from streams, lakes, and wells.  Information on water used for agricultural, industrial, and public supply purposes was obtained from an inventory made in 1965.)

(The purpose of this report is to describe and compare two methods (the tidal-estimation and basin-ratio methods) that were used for estimating discharge and nutrient loads for the tidal reaches of the Myakka and Peace River Basins.  Data were collected during four separate 30-day periods during 1994 and 1995; two of the periods represented low-flow conditions and two represented high-flow conditions.  Both methods were used to compute discharge and nutrient loads for the data-collection periods, and the results were then compared.)
