Sokokis Lake North Dam
Sokokis Lake North
Sokokis Lake North, located in York, Maine, is a concrete dam completed in 1901 for flood risk reduction purposes. With a height of 15 feet and a length of 250 feet, the dam has a storage capacity of 1152 acre-feet and a normal storage level of 768 acre-feet. The lake covers an area of 192 acres and is regulated by the State of Maine, with inspection, permitting, and enforcement measures in place to ensure its safety and functionality.
The dam on Sokokis Lake North is associated with the Brown Brook and serves multiple purposes including fire protection, stock or small fish pond, fish and wildlife habitat, flood risk reduction, and recreation. Despite its age, the dam has a low hazard potential and is in a condition that has not been rated since an assessment in 2012. The surrounding area is supported by a local government as the primary owner, with State jurisdiction and regulatory agency oversight to ensure compliance with safety and environmental standards.
This historical dam structure, nestled in the picturesque landscape of York, Maine, not only serves as a vital flood risk reduction measure but also provides a serene setting for recreational activities and wildlife conservation. With its strategic location and comprehensive state regulation, Sokokis Lake North stands as a testament to the importance of water resource management and climate resilience in ensuring the safety and sustainability of our natural environment.

About Sokokis Lake North
Where does the data for Sokokis Lake North 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 below 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.

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.
