Project Description

The U.S. Department of Agriculture (USDA) Natural Resources Conservation Service (NRCS), with assistance from the Town of Kanosh Corn Creek Irrigation Company (CCIC), and the Kanosh Band of Paiute Indians, , announce the availability of the Draft Watershed Plan and Environmental Assessment (Plan-EA) for the Corn Creek Watershed and Flood Prevention Project in Millard County, Utah (Project). The Project proposes the following improvements to flood prevention and agricultural water management: 

• Corn Creek Dam & Debris Basin: The current debris basin would be removed and a new dam & debris basin constructed downstream that would have an updated alignment slightly farther downstream and a taller embankment.
• Primary, Secondary, Emergency & Auxiliary Spillways: Construction of four new spillways would replace the existing structures, which do not meet current standards.
• Pipe Network/Secondary System: A gravity pipe system to reduce seepage and evaporation losses would be constructed for the CCIC & Kanosh Band.
• Berm & Channel Modification: Installation of channel improvements & other flood control infrastructure to prevent flood damages in Kanosh.
• Pond Relocation & Kanosh Band Secondary System: As part of construction, the Town Secondary Pond would need to be replaced. As a cost saving measure, the Town and Tribe ponds will be combined.

Current Status

NRCS has prepared the Draft Plan-EA and is holding a public meeting on April 22, 2025, where project information will be provided and comments solicited on the Draft Plan-EA. Interested parties may voice their comments, ideas and concerns to NRCS and the project sponsors during this meeting.
