Peru dam
Peru
Peru, located in Beaverhead County, Montana, is home to a small earth dam built in 1943 on the TR-Red Rock River. With a primary purpose of fire protection, stock, or small fish pond, the dam stands at 10 feet high and stretches 150 feet in length, providing a storage capacity of 129 acre-feet. Despite its low hazard potential, the dam is state-regulated and subject to regular inspections, enforcement, and permitting by the DNRC.
The Peru dam serves as a crucial water resource for the local community, offering storage for fire protection and supporting livestock and small fish pond activities. With a normal storage capacity of 66 acre-feet, the dam plays a vital role in ensuring water availability for various purposes in the area. While the dam's condition assessment is currently not rated, its low hazard potential underscores the importance of ongoing monitoring and maintenance to uphold its safety and functionality for the surrounding environment.
Peru's earth dam stands as a testament to the intersection of water resource management and infrastructure development in Montana. As climate change continues to impact water availability and quality, the Peru dam represents a valuable asset for the community, highlighting the importance of sustainable water resource management practices in the face of evolving environmental challenges. By adhering to state regulations and implementing risk management measures, Peru can continue to harness the benefits of its dam while safeguarding against potential hazards and ensuring a reliable water supply 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 Peru
Where does the data for Peru 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.
