The watershed for Langton Lake is approximately 212 acres and is roughly bounded on the east by Fairview Avenue, the west by Cleveland Avenue, the north by County Road D and the south by County Road C. Residential and commercial /industrial land use comprises 47 % and 32.5 %, respectively, of the watershed. Open area, including woods, accounts for about 16 % and roads for about 4 % of the total area of the watershed. The watershed area is small for urban lakes and the development density is fairly low with the exception of the commercial /industrial area in the west and southern portions of the watershed. Langton has 8 acres of land draining to it for each acre of lake surface. The ratio, known as the watershed -to -lake area ratio, often ranges between 10 acres to as high as 200 acres of land per 1 acre of lake for urban watersheds. The relatively low watershed -to- lake -area ratio for Langton Lake suggests that pollutant loadings to the lake should be relatively low and that the lake will retain the water it receives from its watershed for a fairly long time. The lake has three cells, the north, middle and south with surface areas of 3.6, 10 and 9.5 acres respectively. These are described briefly below.
