Lake Jackson watershed study: description of sites, methodology and scope of research. [Impact of urbanization on water quality and geochemistry of watershed of recreational lake in north Florida]
The Lake Jackson watershed study was undertaken to quantify changes in water quality and geochemical exports resulting from urbanization within the 11,900 hectare watershed of a recreational lake in north Florida. Three subbasins of 430, 611, and 792 hectares in size and otherwise similar in all respects except land-use were instrumented for intensive hydrologic and chemical monitoring during a two-year period (June 1973--May 1976). Two of these subbasins offered considerable contrast in major land use: rapidly developing urban versus stable forested-agricultural. The third subbasin was intermediate between these extremes of land use. The streams draining the subbasins were generally intermittent with respect to flow and thus major emphasis was placed on characterizing storm events. Hydrologic records for each water sampling station were studied and water samples were collected both manually and by automatic discrete samplers. Constituents measured included suspended solids, dissolved solids, chloride, dissolved silicon, and dissolved nutrients (nitrogen and phosphorus). The data obtained in this study are being used to identify and explore the hydrochemical consequences of urbanization on a small drainage basin scale.
