Utah officials are analyzing how changing hydrology and prolonged drought may impact state water projects as the 2007 interim operational guidelines for Lake Powell and Lake Mead approach their 2026 expiration. The state is currently engaged in negotiations with other basin states to develop new rules to replace the expiring framework.
A Vital Regional Resource
The Colorado River serves as a vital natural resource for more than 40 million people across seven states and Mexico. According to the Utah Division of Water Resources, the river is often described as the most regulated river in the world, characterized by a complex and extensive history regarding its development and management.
The Law of the River
Utah's relationship with the river is governed by a framework known as "The Law of the River," which includes a collection of compacts, agreements, federal laws, and court decisions. These regulations define how the river is managed and how water is apportioned among the various basin states.
State Water Allocations
Under the 1948 Upper Colorado River Basin Compact, Utah was apportioned 23% of the available water supply within the Upper Basin. The remaining portion of the Upper Basin's water is divided among Colorado at 51.75%, New Mexico at 11.25%, and Wyoming at 14%. Additionally, the portion of Arizona located within the Upper Colorado River Basin was apportioned the right to use 50,000 acre-feet of water annually.
Negotiating Future Guidelines
The current management of the river is facing a transition period. The 2007 interim operational guidelines, which address the coordinated operations of Lake Powell and Lake Mead, are set to expire in 2026. To prepare for this, the Colorado River Basin states are currently engaged in negotiations to develop new operational rules to replace the existing guidelines.
Drought Contingency Planning
In addition to the 2007 guidelines, the 2019 Drought Contingency Plan was developed to address extended drought conditions that were unanticipated by earlier frameworks. This plan, which also expires in 2026, includes several components such as the Companion Agreement, the Upper Basin Drought Response Operations Agreement, the Upper Basin Demand Management Storage Agreement, the Lower Basin Drought Contingency Plan Agreement, and the Lower Basin Drought Contingency Operations.
State Oversight and Management
Utah has taken steps to institutionalize the management of these resources. During the 2021 legislative session, the Utah Legislature created the Colorado River Authority of Utah. This state agency, situated within the Governor’s Office, is tasked with the mission to protect, preserve, conserve, and develop Utah’s interests regarding the Colorado River.
Future Water Demands and Challenges
The Utah Division of Water Resources coordinates with the Colorado River Authority on behalf of Utah citizens to support these conservation efforts. As Utah's population is projected to double by 2065, the state is facing increased demand on its water supplies, making the Colorado River a critical resource for the state's future.
