Lima dam
Lima
Lima, a local government-owned structure in Beaverhead, Montana, plays a crucial role in irrigation along the Red Rock River. Built in 1934, this earth dam stands at a height of 56 feet and boasts a storage capacity of 133,000 acre-feet. The dam covers a surface area of 5900 acres and serves a drainage area of 570 square miles, with a maximum discharge capacity of 47,714 cubic feet per second.
With its satisfactory condition assessment and high hazard potential, Lima Dam presents a vital piece of infrastructure that requires regular inspection and maintenance to ensure its continued functionality and safety. The dam's location in the scenic surroundings of Montana underscores the importance of water resource management in the face of changing climate patterns. As climate enthusiasts, understanding and protecting structures like Lima Dam is essential in safeguarding water resources for future generations.
As water resource and climate enthusiasts, we must recognize the significance of structures like Lima Dam in sustaining agricultural activities and maintaining water security in the region. With its role in irrigation and flood control, Lima Dam serves as a testament to human ingenuity in managing water resources. By staying informed about the condition and management of such structures, we can contribute to sustainable water management practices and climate resilience efforts in our communities.

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 Lima
Where does the data for Lima 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 High 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.
