Gascoyne Township Dam dam
Gascoyne Township Dam
Gascoyne Township Dam, located in Bowman, North Dakota, serves multiple purposes including fire protection, stock, and small fish pond management. Constructed in 1936 by USFWS and WPA, this earth dam stands at a height of 19 feet and spans a length of 425 feet, with a storage capacity of 305.2 acre-feet. The dam is regulated by NDSWC and undergoes regular inspections, with a low hazard potential and a moderate risk assessment score of 3.
Despite its modest size and low hazard potential, Gascoyne Township Dam plays a crucial role in water resource management for the region. With a surface area of 30 acres and a drainage area of 4.55 square miles, the dam helps to regulate water levels in Dry Coulee and provides essential water resources for local fire protection and agricultural activities. The dam's uncontrolled spillway, measuring 50 feet in width, ensures proper water flow during periods of high precipitation.
Gascoyne Township Dam's historical significance, combined with its ongoing role in water management and environmental conservation, highlights the importance of maintaining and monitoring these essential infrastructure assets. As a key component of the local government's water resource strategy, the dam stands as a testament to the enduring legacy of New Deal-era public works projects and continues to serve the community with its vital functions in mitigating flood risks and supporting sustainable water use practices.

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 Gascoyne Township Dam
Where does the data for Gascoyne Township 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.
