Three separate watershed assessments were performed to guide the development of a watershed management plan for the North Branch Park River: 1) a Baseline Watershed Assessment, 2) a Watershed Field Assessment, and 3) a Land Use Regulatory Review. The Baseline Watershed Assessment evaluates the existing environmental and land use conditions in
Watershed, a watershed that flows toward the Columbia River. In this way, one watershed is artificially connected to several other watersheds at once. The watershed of surface flow, the watershed where domestic water originates, and the watershed where wastewater goes

the Genesee County Soil and Water Conservation Districts’s prior experience with watershed collaboration will be a great help in this planning effort. They will be able to share their knowledge in the formation and direction of this watershed alliance. The watershed alliance is the first phase of a multi-phased watershed project that will benefit
