R E Peterson #1 dam
R E Peterson #1
R E Peterson #1 is a privately owned dam located in Hardin, Montana, along the TR-North Fork Two Leggins Creek. Built in 1953, this earth dam stands at a height of 10 feet and has a storage capacity of 50 acre-feet, primarily serving the purposes of fire protection, stock watering, and small fish pond. The dam is regulated by the Montana Department of Natural Resources and Conservation (DNRC), with state jurisdiction and permitting in place for inspection and enforcement.
Despite its low hazard potential, R E Peterson #1 has not been rated for its condition assessment, and there are no emergency action plans or risk assessment measures documented for the dam. The structure's construction and maintenance have not involved any federal agencies, with the responsibility falling solely on the private owner. With a maximum storage capacity of 50 acre-feet and a normal storage level of 11 acre-feet, the dam plays a crucial role in water resource management in the area.
For water resource and climate enthusiasts, R E Peterson #1 serves as a noteworthy example of a privately owned dam contributing to local water supply and resource management efforts. Its location in Big Horn County, Montana, and its historical significance since 1953 make it a valuable asset for understanding the role of small-scale dams in supporting various community needs, including fire protection and livestock watering. Further assessment of its condition and the development of emergency preparedness plans could enhance its overall safety and resilience in the face of potential climate challenges.
Dam data reference
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 R E Peterson #1
Where does the data for R E Peterson #1 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.
