Evaluation of the Installation of a Sewage Collection System on Water Quality in a Prairie Lake

摘要

From 1968-75 extensive studies supported by EPA and OWRR were done to determine the rate and extent of the aging process in Lake Madison, a 3000-acre shallow glacial prairie lake surrounded by about 600 homes near Madison, South Dakota. Since then several specific things have been done to try to slow the eutrophication of the lake. A sewage collection system for all the homes around Lake Madison was initiated in 1987 and scheduled for completion in 1988. In order to compile a profile of selected water quality parameters in Lake Madison, Dakota State University conducted water analysis studies in Lake Madison in the summer of 1987. The primary objectives of the research were to continue to develop base-line data prior to and during the first year that the sewage collection system is on-line.
