responsibly develop, conserve, and deliver water

Diamond Fork Creek and Sixth Water Creek
Instream Flow Studies

In 2015, the Central Utah Water Conservancy District, Utah Reclamation Mitigation and Conservation Commission, and United States Department of the Interior, Central Utah Project Completion Act Office, as Joint Lead Agencies (JLAs), determined that winter instream flows for Diamond Fork River can no longer be delivered from the Sixth Water Flow Control Structure. The JLAs then implemented a funding agreement with Utah State University (USU) scientists to conduct studies during 2016-2018 to determine desired instream flow regimes to maximize ecological health on the river systems.

Later this summer and fall, the JLAs will engage stakeholders in the decision-making process about implementing the recommendations. Check back for announcements about upcoming engagement opportunities.
