Perry Station Dam dam
Perry Station Dam
Perry Station Dam, located in Washington County, Maine, is a concrete buttress dam completed in 1911 with a primary purpose of water supply. Situated on Boyden Stream, this dam stands 20 feet tall and spans 145 feet in length, with a storage capacity of 83 acre-feet. Despite its age, the dam is in fair condition and is regularly inspected by the Maine Emergency Management Agency to ensure its structural integrity and safety.
The dam's significant hazard potential necessitates a thorough inspection every six years, with the most recent assessment conducted in October 2019. While the dam meets state regulatory requirements and has a state permit for operation, there are currently no emergency action plans in place, raising concerns about preparedness in case of a dam failure. With its location in a critical watershed area and its role in providing water supply, stakeholders and authorities must prioritize the implementation of risk management measures to mitigate potential hazards and ensure the long-term safety and sustainability of Perry Station Dam.
As a vital infrastructure for water resource management in the region, Perry Station Dam underscores the importance of proactive maintenance and risk assessment for aging dams. Climate change impacts on water resources further emphasize the need for resilient infrastructure that can withstand extreme weather events. By addressing potential vulnerabilities and implementing effective emergency response plans, Perry Station Dam can continue to fulfill its crucial role in water supply while minimizing risks to downstream communities and the environment.

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 Perry Station Dam
Where does the data for Perry Station 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 Significant 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.
