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 Irrigation Company, Wellsville City, Mendon City, and Wellsville Mendon Conservation District, are considering proposed improvements within the Wellsville Canyon and Threemile Creek Watersheds, Cache County, UT.

  1. Flood Prevention
    • Culvert replacements
    • Channel stabilization measures
    • Detention basins
  2. Agricultural Water Management
    • Pressurized secondary irrigation system to improve reliable irrigation water supply and provide sustainable conveyance system
    • Diversion structures
  3. Recreation
    • Opportunities at Wellsville Reservoir
