Corn Creek Watershed Plan-EA  –  Project FAQ Sheet


Project Description

The United States Department of Agriculture Natural Resources Conservation Service (NRCS), with Kanosh Town as the project sponsor and Corn Creek Irrigation Company as project co-sponsor with the Kanosh Band of Paiutes Tribe as project participants, is proposing to partially fund watershed protection measures through the Watershed Protection and Flood Prevention Act (Public Law [PL] 83-566) in the Corn Creek Watershed, Millard County. The main objective of the project is to address concerns about flooding potential, potential failure of the existing debris basin due to seepage that is occurring in the embankment’s foundation and water shortages each irrigation season caused by reduced flow in Corn Creek as the year progresses, which increases demand on groundwater resources, limits crop production and cropping options, and impacts economic development in Kanosh.

Conceptual improvements may include:

  1. Flood Prevention
    • New reservoir/debris basin
    • Route flood flows around town and/onto fields
    • Improve recharge of primary aquifer
  2. Agricultural Water Management
    • Improve irrigation water supply
    • Provide sustainable pressurized conveyance system
    • Increase reliability of water deliveries to Paiute tribal lands

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.


Current Status

The Draft Plan-EA has been reviewed by NRCS-Utah, who had minimal comments. After these comments are addressed, the Draft Plan-EA will be submitted to the National Watershed Management Center (NWMC) for final review and approval.
