Twin Forks (Dawson) dam
Twin Forks (Dawson)
Twin Forks (Dawson) is a privately owned Earth dam located in Glendive, Montana, in Dawson County. Completed in 1961, this dam serves the primary purpose of flood risk reduction along the TR-LABELL DITCH river or stream. With a height of 35 feet and a length of 220 feet, Twin Forks (Dawson) has a storage capacity of 218 acre-feet, providing essential protection to the surrounding area from potential flooding events.
Managed by the Montana Department of Natural Resources and Conservation (DNRC), Twin Forks (Dawson) is regulated, permitted, inspected, and enforced by the state agency to ensure its structural integrity and operational efficiency. Despite its low hazard potential, the condition of the dam has not been formally assessed and rated. The emergency action plan (EAP) status, risk assessment, and management measures for Twin Forks (Dawson) remain unknown, highlighting the importance of ongoing monitoring and maintenance to safeguard against any unforeseen risks or emergencies.
Located within Congressional District 00, Montana, Twin Forks (Dawson) plays a crucial role in protecting the local community and environment from potential flooding events. As water resource and climate enthusiasts, understanding the significance of dams like Twin Forks (Dawson) in mitigating flood risks and ensuring water security is essential for promoting sustainable water management practices and resilience in the face of changing 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.

About Twin Forks (Dawson)
Where does the data for Twin Forks (Dawson) 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.
