Total suspended solids (TSS) loading throughout the Stephens subwatershed is medium with some areas of high and low loading. This reflects the residential land use found in this subwatershed. High loading is found along the main highway that cuts through the subwatershed, while pockets of low loading correspond with E-zones and a Cemetery.
