The Wyoming Water Development Commission shelved a study intended to measure water loss in irrigation ditches after the contractor could not gain access to all planned sites. The project, which received a $500,000 legislative appropriation in 2023, failed to reach the statistical significance required for basin-wide data.
Why it matters
The study was abandoned because landowners remained divided on granting property access, highlighting ongoing difficulties for utilities and researchers attempting to quantify water usage across private lands. This operational roadblock now leaves the state without the comprehensive data originally sought for the Green River and Little Snake River basins.
The project was allocated $500,000 in 2023 with $400,000 awarded to the contractor, yet only 12 of the 20 planned irrigation ditches were surveyed. The incomplete data set failed to meet statistical significance for characterization of the Green River and Little Snake River basins.
The players
Wyoming Water Development Commission
A state agency responsible for the planning and funding of water development projects across Wyoming.
Stantec Consulting Services
A global engineering and design firm that provides technical consulting services for infrastructure and water management projects.
The details
The project scope was complicated by the basins' geography, which featured smaller ditches with multiple diversion points. These logistical challenges were compounded by the lack of existing measurement flumes at the head of many ditches, which increased the technical and financial burden on the contractor. Ultimately, the contractor could not secure the necessary property access to complete the full scope of the study.
Timeline
In 2023, the Wyoming legislature appropriated $500,000 for the study.
In 2024, the commission awarded $400,000 to Stantec Consulting Services.
In April 2024, the contractor held two public project meetings.
In September 2026, the commission reported the project status in Cheyenne.
Market Landscape
The state's abandoned measurement effort highlights the difficulty of gathering granular water data in complex river basins. It follows a pattern set by the Upper Colorado River Commission's basin-wide study, which is currently attempting to quantify incidental water use on a larger scale.
Operators in the agricultural and utility sectors should anticipate that future water management assessments will likely face similar land-access and infrastructure hurdles. Stakeholders should monitor regional water initiatives for new methodologies that may circumvent the need for extensive private-property access.
The takeaway
The failure to complete this survey suggests that future water studies will require more robust community outreach or different measurement technologies to succeed. Operators should track the progress of the Upper Colorado River Commission's basin-wide study to see if it adopts alternative data-gathering methods.
