Eagle Lake Pollution Control Project,Eagle Lake, Kandiyohi County,Minnesota. Bench Mark Studies.

摘要

The report describes cooperative efforts of a lake community and several governmental agencies to alleviate increasing cultural eutrophication in Eagle Lake, Kandiyohi County,Minnesota. Two non-point nutrient sources were identified:Agricultural runoff and domestic sewage. A lake-encircling collection line now diverts the sewage to a treatment plant. Earthen dams with soil absorption fields have been tested as a means of removing nutrients from part of the watershed runoff. Detailed studies of the chemical,physical,and biological conditions in the lake were conducted before the sewage system was completed. Water and nutrient budget estimates have been made. Eagle Lake can be classified as moderately eutrophic.
