Senate approves Colorado River authority bill after heated debate over costs and representation

The Utah Senate passed first substitute House Bill 297 on March 3, authorizing a new body to help preserve and defend the state’s Colorado River allocation. Sponsors described the bill as a technical and legal shield to protect Utah’s legal rights to river water as flows and legal pressure change.

“Water is the limiting factor for growth,” Senate President Adams said on the floor, arguing the state needs technical specialists, engineers and legal experts to conserve and defend Utah’s share of the Colorado River. Proponents said the measure follows models used in other states and will help coordinate conservation and legal strategy.

Opponents raised questions about cost, representation and transparency. Senator Kitchen described the proposal as a new $9.6 million agency aimed at litigation and said the bill has drawn concern about exemptions from conflict-of-interest rules and limited local or tribal representation on governing boards. Senator Riebe and others urged clearer membership rules and broader inclusion of residents who live in affected areas.

Supporters argued the new authority is a defensive tool to protect existing rights and noted other Western states have adopted similar entities. Senator Thatcher said Utah must act to protect long-term water access for rural counties and growing communities.

Floor debate lasted multiple hours and included questions about potential litigation costs, agency governance and whether conservation and non-capital options were fully considered. The president ultimately moved the bill under suspension of rules; the president recorded the vote and declared the bill passed (transcript-recorded tally appears in the floor record). The bill will be returned to the House for further consideration.
