The report covers the geographical, geological, and hydrological character of the Indian Creek Reservoir area; the general limnological aspects of the reservoir; and the nature and findings of physical, chemical, and biological analyses of the reservoir water. The study relates these characteristics of the reservoir water to the nutrient concentrations and biostimulatory characteristics of the influent waste water, and evaluates the relative contribution of biostimulants in the treated effluent and in the underlying soil and sediment exchange.
