Last data update: January 5, 2009 Defined as an analogy to the concept of natural watershed, which refers to an area draining to a single point in a stream network, sewersheds are determined by curbs, storm drains, settling basins, pipes, and outfalls to streams. Often storm sewers or the collecting curbs and drains cross the boundaries of the watersheds that existed before urbanization. Created by LSRCA monitoring staff through a combination of field surveys and municipal drainage information.
