Hey Ray #2 dam
Hey Ray #2
Hey Ray #2 is a privately owned earth dam located in Loma, Montana, along the TR-Pondera Coulee. Completed in 1958, the dam serves multiple purposes including fire protection, stock, and small fish pond maintenance. With a height of 61 feet and a storage capacity of 133 acre-feet, Hey Ray #2 plays a crucial role in water resource management in the area.
Managed by the Montana Department of Natural Resources and Conservation (DNRC), Hey Ray #2 has a low hazard potential and is currently in a "Not Rated" condition assessment status. The dam has not been inspected or assessed for emergency preparedness, but it meets state regulatory requirements for inspection, permitting, and enforcement. Although located in a remote area, the dam's importance for local water resources and climate resilience cannot be understated.
Water resource and climate enthusiasts will be intrigued by Hey Ray #2's role in supporting fire protection, stock management, and ecological preservation in Chouteau County, Montana. As a key structure along the TR-Pondera Coulee, the dam's history, design, and purpose offer valuable insights into the intersection of water management, environmental stewardship, and community resilience in the region. With its low hazard potential and state-regulated status, Hey Ray #2 stands as a testament to the importance of sustainable water resource infrastructure in the face of changing climate 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 Hey Ray #2
Where does the data for Hey Ray #2 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.
