Daly Flowage Dam dam
Daly Flowage Dam
Daly Flowage Dam, located in Washington, Maine, is a Federal-owned structure managed by the US Fish and Wildlife Service Office of Engineering. This earth-type dam was completed in 1950 and serves as a vital component of the Moosehorn Brook Tributary, providing water resource management for a Fish and Wildlife Pond. With a height of 10 feet and a length of 350 feet, the dam has a storage capacity of 285 acre-feet, making it a significant contributor to the local ecosystem.
Despite its importance, Daly Flowage Dam is currently rated as being in poor condition, with a hazard potential deemed low. The dam has a very high risk assessment rating, indicating the need for immediate attention and potential risk management measures. The last inspection took place in June 2014, with an inspection frequency of 5 years. As a controlled spillway type dam with other controlled outlet gates, the structure requires regular monitoring and maintenance to ensure its continued functionality and safety for both the environment and surrounding communities.
Given its critical role in water resource management and wildlife preservation, Daly Flowage Dam warrants ongoing attention and investment to address its current poor condition and mitigate the very high risk assessment rating. This Federal-owned structure must be regularly inspected and maintained to ensure its effectiveness in supporting the local ecosystem and managing water resources in the Moosehorn Brook Tributary. Collaborative efforts between regulatory agencies and the Fish and Wildlife Service are essential to safeguarding the dam's integrity and preventing potential hazards in the future.

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 Daly Flowage Dam
Where does the data for Daly Flowage 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.
