Larry Pilster #2 dam
Larry Pilster #2
Larry Pilster #2 is a privately owned earth dam located in Carter, Montana, near Camp Crook, South Dakota. Completed in 1950, this dam serves multiple purposes including fire protection, stock, and small fish pond management. With a height of 10 feet and a length of 300 feet, Larry Pilster #2 has a storage capacity of 232 acre-feet and a maximum storage capacity of 232 acre-feet. Situated on the TR-North Fork Willow Creek, this dam is regulated by the Montana Department of Natural Resources and Conservation (DNRC) with state permitting, inspection, and enforcement in place to ensure its safety and compliance.
Despite its low hazard potential, Larry Pilster #2 has not been rated for its condition assessment, indicating a need for further evaluation. The dam does not have an Emergency Action Plan (EAP) prepared, and its risk assessment and management measures are currently unspecified. Additionally, the dam lacks inundation maps and updated emergency contacts. However, with its state-regulated status and regular inspections, Larry Pilster #2 remains a vital resource for water management in the region. As water resource and climate enthusiasts, it is essential to monitor and assess the condition of this dam to ensure its long-term sustainability and safety for the surrounding community.
Located in Congressional District 00 of Montana, Larry Pilster #2 plays a crucial role in water management and conservation efforts in the area. As a privately owned structure, it highlights the importance of collaboration between private owners and state regulatory agencies in maintaining the integrity of water resources. With its historical significance and multi-purpose functionality, Larry Pilster #2 serves as a valuable asset for fire protection, livestock watering, and ecological preservation. By staying informed and engaged with the ongoing maintenance and assessment of this dam, water resource and climate enthusiasts can contribute to the sustainable management of this essential infrastructure for future generations.

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 Larry Pilster #2
Where does the data for Larry Pilster #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.
