Lake Pollution from Entering Streams C. C. DEWITT AND J. F. WHITE Michigan State College East Lansing, Michigan This is a preliminary report of a waste disposal study sponsored by the Gerber Products Company of Fremont, Michigan. The data reported were obtained from samples taken near the mouth of Darling Creek which flows into Fremont Lake. It has been established that when water carrying waste material enters a flowing stream, the waste material can be detected for a con¬ siderable distance downstream. A different situation exists when waste material is discharged into large, relatively still bodies of water such as the Great Lakes or tidal basins. Small, non-stagnant lakes are not included in these classes of waste receivers. Dams in streams produce bodies of water resembling many small inland lakes in that they possess both a flowing inlet and outlet. In many surveys of stream pollution the samples have been obtained near the dam spillway. Public health officials express the opinion, however, that the pollution in a small lake is local in character. The data presented show that pollution is confined to the area near the lake inlet. In the present instance both the industrial and sewage wastes are treated by the Fremont municipal sewage disposal plant. The industrial waste volume from the cannery represents about two-thirds of the total volume. At the disposal plant solids are settled and sent to a digester, the effluent from the settling chamber is treated in a high-rate biological filter. The final effluent is partially chlorinated; this effluent enters Darling Creek about one-half mile upstream from its mouth. The creek enters the lake near the most northeasterly portion; the lake outlet is diagonally southwest. The water is controlled by a spillway dam at the outlet. The lake area is approximately 800 acres; its maxi¬ mum measured depth about 90 feet. The lake bottom is marl, with a small sand beach near the creek mouth. The lake shore adjacent to the creek mouth has been protected against erosion by rocks and broken concrete. The entire north lake shore is residential; much of the remaining shore line is reedy with farm land beyond. In September, 1944, representatives of the Stream Control Com¬ mission of the State of Michigan made two series of tests on Fremont 190
