The Watershed Management Plan includes maps, planning materials, water quality data, design criteria for implementation activities, and scoring of stream segments. The Watershed Management Plan was approved on February 10, 2006 under United States Environmental Protection Agency Guidelines.

The watershed for these two creeks encompasses 43,700 acres within the Cities of Kalamazoo and Portage, and Oshtemo, Texas and Kalamazoo Townships in Kalamazoo County. These streams discharge to the Kalamazoo River within the City of Kalamazoo. Two major tributaries flow into Portage Creek before it joins with the Kalamazoo River. Thus, there are four individual drainage areas considered for this long range planning effort.
