Crow #69 dam
Crow #69
Crow #69 is a privately owned earth dam located in Lodge Grass, Montana along Alligator Creek. Built in 1955, this dam serves multiple purposes including fire protection, stock watering, and maintaining a small fish pond. With a height of 15 feet and a length of 125 feet, the dam has a storage capacity of 64 acre-feet and a normal storage capacity of 25 acre-feet. Despite its low hazard potential, the dam is state-regulated and subject to inspections, ensuring its continued safety and functionality.
Managed by the Montana Department of Natural Resources and Conservation (DNRC), Crow #69 is an essential component of the local water resource infrastructure. Its strategic location in Big Horn County plays a crucial role in providing water for various purposes while also minimizing the risk of flooding and enhancing the ecosystem along Alligator Creek. With proper regulatory oversight and maintenance, this dam continues to contribute to the sustainable management of water resources in the area.
As a valuable asset in the region, Crow #69 exemplifies the importance of proper dam management in the context of water resource and climate considerations. By maintaining its structural integrity and storage capacity, this dam not only supports fire protection and agricultural activities but also helps mitigate potential water-related risks in Lodge Grass, Montana. As water enthusiasts and climate advocates, staying informed about the condition and regulatory status of dams like Crow #69 is essential for promoting water sustainability and resilience in the face of changing environmental conditions.

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 Crow #69
Where does the data for Crow #69 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 Low 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.
