Wellsville-Mendon Watershed (Sponsor = Cache Water District)

Project Description

The United States Department of Agriculture Natural Resources Conservation Service (USDA-NRCS), with assistance from Cache Water District as the project sponsor, and several co-sponsors including Cache County, Wellsville City Irrigation Company, Wellsville City, Mendon City, and Wellsville Mendon Conservation District, are considering proposed improvements within the Wellsville Canyon and Threemile Creek Watersheds, in Cache County, UT.

The proposed project would prevent or reduce flooding, enhance wildlife habitat, and improve irrigation water delivery.  Conceptual improvements may include:

  • Flood Prevention
    • Culvert replacements
    • Channel stabilization measures
    • Detention basins
    • Flood diversion structures
  • Agricultural Water Management
    • Pressurized secondary irrigation system to improve reliability of irrigation water supply and provide sustainable conveyance system
    • Water control structures
  • Recreation
    • Opportunities at Wellsville Reservoir

NEPA Analysis

NRCS, as the lead federal agency, is initiating National Environmental Policy Act (NEPA) analysis in the form of a Watershed Plan and Environmental Assessment (Plan-EA) to analyze impacts to the natural and human environment from this project. The Plan-EA will comply with the Council on Environmental Quality’s regulations at 40 CFR Parts 1500-1508 and the Natural Resources Conservation Service Regulations (7 CFR Part 650), which require an evaluation of potential environmental impacts associated with federal projects and actions.
