Coal Mine Lake Dam dam
Coal Mine Lake Dam
The Coal Mine Lake Dam in North Dakota, completed in 1936, serves as a vital resource for fish and wildlife conservation, with a primary purpose of creating a pond for these species. The dam, made of Roller-Compacted Concrete, stands at a height of 8 feet and has a storage capacity of 8,775 acre-feet. The dam is also equipped with a controlled spillway with a width of 50 feet to manage water flow and prevent overflow.
Located in Sheridan County, North Dakota, the Coal Mine Lake Dam sits on the Sheyenne River and is regulated by the North Dakota State Water Commission. Despite being categorized as having a low hazard potential, the dam is considered to have a very high risk assessment, which suggests the need for careful monitoring and maintenance. With a surface area of 1,162 acres and a drainage area of 0.39 square miles, the dam plays a crucial role in the local ecosystem and water management efforts in the region.
Overall, the Coal Mine Lake Dam is an essential structure for wildlife preservation and water resource management in North Dakota. With its focus on fish and wildlife conservation, the dam serves as a key component of the state's efforts to protect and sustain its natural habitats. Despite its low hazard potential, the dam's high risk assessment underscores the importance of ongoing monitoring and maintenance to ensure its continued effectiveness and safety for both wildlife and nearby 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.
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 Coal Mine Lake Dam
Where does the data for Coal Mine Lake Dam 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.
