About this dam

Gunnison

Located in Gunnison, Utah, the Gunnison Dam stands as a vital structure for irrigation purposes along the San Pitch River. Completed in 1889, this earth dam has a hydraulic height of 28 feet and a structural height of 42 feet, with a storage capacity of 33,000 acre-feet. The dam plays a crucial role in managing water resources in the region, with a normal storage capacity of 12,800 acre-feet and serving as a key component of the local water infrastructure.

Managed by the Utah Division of Water Rights, the Gunnison Dam is regulated, inspected, and enforced by state authorities, ensuring its safe operation. The dam has a high hazard potential but has been assessed as satisfactory in condition. With a spillway width of 164 feet and a length of 1,240 feet, the dam is equipped to handle potential risks and emergencies effectively. The last inspection conducted in July 2020 reaffirmed the dam's structural integrity and functionality, highlighting its importance for water management in the area.

For water resource and climate enthusiasts, the Gunnison Dam offers a fascinating insight into the intersection of engineering, infrastructure, and environmental stewardship. As a key irrigation structure in Sanpete County, Utah, the dam plays a crucial role in supporting agricultural activities and water supply management along the San Pitch River. With its long history and continued importance in the region, the Gunnison Dam stands as a testament to the ingenuity and foresight of water resource management in the American West.

Condition Assessment

Satisfactory
No existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action.
Poor
A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.

Hazard Potential Classification

High
Dams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environmental damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.

FAQ

About Gunnison

Where does the data for Gunnison come from?

Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.

How often is the report updated?

NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.

What does the High hazard rating mean?

The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.

What's "% of normal"?

The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).

Can I get alerts when storage crosses a threshold?

Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
