About this dam

Heifer Pen

Heifer Pen is a privately owned water resource located in McCone County, Montana, near the city of Frazer. Built in 1950 by the USDA NRCS, this earth dam serves multiple purposes including fire protection, stock, and small fish pond. With a dam height of 24 feet and a storage capacity of 113 acre-feet, Heifer Pen is regulated by the Montana Department of Natural Resources Conservation (DNRC) and is subject to state inspection and enforcement.

Situated on TR-LOST CREEK, Heifer Pen plays a crucial role in water management and agricultural activities in the region. The dam has a low hazard potential and is currently rated as "Not Rated" in terms of its condition assessment. Despite lacking specific information on inspections and emergency preparedness, the dam continues to serve its intended purposes effectively, providing essential water resources for the local community while also contributing to fire protection and wildlife habitat.

As a vital infrastructure for water storage and management, Heifer Pen underscores the importance of sustainable water resource development in the face of climate change. With its strategic location and capacity to store water, the dam not only supports agricultural activities but also enhances environmental resilience in the region. As water resource and climate enthusiasts, understanding and monitoring the condition of dams like Heifer Pen is crucial for ensuring the long-term sustainability of water sources and ecosystems in the face of evolving climatic challenges.

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 Heifer Pen

Where does the data for Heifer Pen 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.
