Glenharold Mine 143-84-09-3h dam
Glenharold Mine 143-84-09-3h
Glenharold Mine 143-84-09-3h is a private earth dam located in Oliver, North Dakota, with a primary purpose of providing fire protection, stock, or serving as a small fish pond. The dam, completed in 1980, has a height of 20 feet and a storage capacity of 59.1 acre-feet. It is regulated by the North Dakota State Water Commission and undergoes regular inspections, with a low hazard potential and a moderate risk assessment rating.
Situated on the Missouri River tributary, the dam has a surface area of 3.5 acres and serves a drainage area of 0.86 square miles. The spillway is uncontrolled with a width of 10 feet, and there are no outlet gates associated with the structure. While the condition assessment is marked as "Not Rated," the dam's risk management measures and emergency preparedness status are not explicitly mentioned. Despite its low hazard potential, the dam plays a crucial role in providing essential services to the surrounding area and maintaining water resources for various purposes.
Overall, Glenharold Mine 143-84-09-3h is a vital water resource infrastructure in North Dakota, serving multiple functions and contributing to the local ecosystem. With its completion in 1980, the dam continues to provide fire protection, stock water, and recreational opportunities in the region. While the risk assessment indicates a moderate level of risk, the dam's structural integrity and regulatory oversight ensure its safe operation and maintenance. As a point of interest for water resource and climate enthusiasts, this earth dam exemplifies the intersection of human intervention and natural water systems in the ongoing management of water resources.
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 Glenharold Mine 143-84-09-3h
Where does the data for Glenharold Mine 143-84-09-3h 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.
