Crosby dam
Crosby
Located in Big Horn, Wyoming, the Crosby dam on Gypsum Creek stands as a vital structure for irrigation purposes since its completion in 1980. This private-owned earth dam, with a height of 40 feet and a length of 440 feet, provides essential water storage with a capacity of 142 acre-feet. Despite its significant hazard potential and poor condition assessment, the dam remains under state regulation and inspection to ensure its safety and functionality.
With a spillway width of 10 feet and a maximum discharge capacity of 204 cubic feet per second, Crosby dam plays a crucial role in managing water flow and preventing potential flooding downstream. The dam's location and design make it a key component in the water resource infrastructure of the area, supporting agricultural activities and environmental conservation efforts. Despite its poor condition assessment, ongoing inspections and regulatory oversight help mitigate risks and ensure the dam's continued operation.
Crosby dam's significance as an irrigation structure on Gypsum Creek underscores the intersection of water resource management and climate resilience in Wyoming. As water resources become increasingly strained due to changing climate patterns, maintaining and improving infrastructure like Crosby dam becomes essential for sustainable water supply and ecosystem health. Ongoing risk assessments and management measures will be crucial in safeguarding this vital water resource for the future.

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.

About Crosby
Where does the data for Crosby 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 Significant 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.
