Lars Borg dam
Lars Borg
Lars Borg is a private water structure located in Richland, Montana, specifically in the city of Dore North Dakota. Built in 1977, this earth dam stands at a height of 23 feet and has a storage capacity of 503 acre-feet. Primarily used for fire protection, stock, or as a small fish pond, Lars Borg sits on Four Mile Creek and is regulated by the Montana Department of Natural Resources and Conservation.
This dam has a significant hazard potential and has not been rated for its condition assessment. Despite this, it is regularly inspected, permitted, and enforced by the state regulatory agency. With a maximum storage capacity of 503 acre-feet and a normal storage capacity of 234 acre-feet, Lars Borg serves as a crucial resource for water management and conservation in the area. Its location, design, and purpose make it an essential structure for maintaining water resources in the region, especially for fire protection and agricultural needs.
For water resource and climate enthusiasts, Lars Borg presents an intriguing case study of a privately owned water structure that plays a vital role in maintaining water supply and supporting local ecosystems. Its construction, management, and regulatory oversight provide valuable insights into the challenges and opportunities associated with water infrastructure in Montana. As climate change continues to impact water resources, structures like Lars Borg will be crucial for ensuring water security and resilience in the face of evolving environmental conditions.

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.
Plan around the weather
Same NOAA / yr.no feed Snoflo's iOS app uses. Watch the precipitation column on the meteogram -- rain on the basin upstream typically lifts inflow 24-72 hours later.

About Lars Borg
Where does the data for Lars Borg 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 Significant 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.
