BATTLE CREEK KRIS V 2.0 SUB BASINS: Outlines of Sub Basins were produced by Dr. Paul Trichilo of Kier Assoc and the KRIS Team by aggregating Calwater Planning Watersheds V 2.2. Sub basins were designed to frame the natural drainage systems within the hydrobasin. Unfortunately, Calwaters do not necessarily follow natural drainages, but the North Fork and South Fork sub-basins are actual hydrologic units. The Main Battle sub-basin is the balance of the basin outside the NF or SF, but is actually comprised of numerous smaller tributaries as well as the lower mainstem Battle Creek. Projection: UTM
