Diamond Fork System Environmental Update Project



The Central Utah Water Conservancy District (District), the U.S. Department of the Interior, Central Utah Project Completion Act Office, and the Utah Reclamation Mitigation and Conservation Commission, as Joint Lead Agencies (JLAs), are proposing to

  1. adjust instream flow deliveries to Sixth Water and Diamond Fork Creeks to support and sustain functional fluvial, geomorphic, and ecological processes;
  2. provide the flexibility necessary to meet inspection and maintenance requirements of the Diamond Fork System to continue the delivery of contracted water and instream flows; and
  3. prevent the continuous corrosion of the Upper Diamond Fork Flow Control Structure from nearby hydrogen sulfide springs.

In 2015, the JLAs, determined that winter instream flows for Diamond Fork Creek can no longer be delivered from the Sixth Water Flow Control Structure. The JLAs then contracted with Utah State University scientists to conduct studies during 2016-2019 to determine desired instream flow regimes to maximize ecological health on the creek systems. This report is found on the link below.

Final Instream Recommendations

The JLAs are preparing an environmental assessment (EA) for the Diamond Fork System Environmental Update (proposed action) to meet the requirements of the National Environmental Policy Act. The JLAs have prepared a Scoping Document which outlines the proposed project. The Scoping Document is found on the link below.
