Shingle Creek是佛罗里达州托伊卡利加湖的主要流入地。托伊卡利加湖的水质和营养状况受到瓦河水质的强烈影响。本报告记录了10年的水质数据在瓦溪在湖泊排污口，前（1981年10月至1986年12月）和后废水排放（1987年1月至1991年9月）去除期。营养预算的子流域计算从一个激烈的研究计划（1983年1月至1985年12月），以记录installation的影响归因于废水，确定的作用，柏树沼泽中的子流域，并记录水质和土地利用之间的关系。在研究期间，快速的城市化将森林高地和农业用地转变为住房和商业用地。佛罗里达的雨水径流已被确定为主要污染源。自1982年以来，佛罗里达州通过最佳管理实践（BMPs）对雨水污染进行了管理。到1988年，84%的城市土地使用在上游盆地受到雨水处理之前被排放到小溪。雨水管理、明矾处理和城市废水分流抵消了城市来源养分投入的潜在增加。氮负荷和Pmore »负荷和方差显着下降，在10年期间，尽管在北方和中央次盆地的快速城市化。子流域的养分输出受到主导土地利用的影响。中间次盆地包含一个沼泽，贡献了最大的P和Cl{sup -}负荷，因为增加排放到沼泽的来源以外的运河。北方城市次流域接收废水排放，并作为一个净汇的N和P输出的次流域。参考文献24篇，图9，1个选项卡。«少
Shingle Creek is a major inflow to Lake Tohopekaliga, Florida. Water quality and the trophic status of Lake Tohopekaliga are affected strongly by the water quality of Shingle Creek. This report documents 10 yr of water quality data in Shingle Creek at the lake outfall; for a pre- (October 1981-December 1986) and a post-wastewater discharge (January 1987-September 1991) removal period. Nutrient budgets for the subbasins were calculated from an intense research program (January 1983-December 1985) to document instream impacts attributable to wastewater, determine the role of the cypress swamp in the middle subbasin, and document relationships between water quality and land uses. Rapid urbanization converted forested uplands and agricultural lands to housing and commercial land use during the study. Stormwater runoff in Florida has been identified as a major pollution source. Treatment of stormwater pollution, through Best Management Practices (BMPs), has been regulated by the State of Florida in this area since 1982. By 1988, 84% of the urban landuse in the upper basin was subject to stormwater treatment prior to being discharged to the creek. Potential increases in urban derived nutrient inputs were offset by stormwater management, and alum treatment and diversion of municipal wastewater. Nitrogen loading and Pmore » loads and variance decreased significantly during the 10-yr period, despite rapid urbanization in the northern and central subbasins. Nutrient export from the subbasins was influenced by the dominant land use. The middle subbasin contains a swamp that contributed the greatest P and Cl{sup -} loads because of the increase in discharge to the swamp from sources other than the canal. The northern urban subbasin received the wastewater discharges and served as a net sink for N and P exported from the subbasin. 24 refs., 9 figs., 1 tab.« less
