Symmes Pond dam
Symmes Pond
Symmes Pond, located in York, Maine, is a privately owned reservoir with a fascinating history dating back to its completion in 1969. This Earth and Gravity dam stands at a height of 9 feet and has a storage capacity of 105 acre-feet, providing recreational opportunities and serving as a crucial water resource in the area. The dam, situated on Symmes Pond Brook, has a surface area of 36 acres and a drainage area of 1.2 square miles, making it an integral part of the local ecosystem.
Despite its age, Symmes Pond dam is in fair condition with a low hazard potential, as assessed in 2011. The dam's inspection frequency is set at 12 months, ensuring regular maintenance and compliance with state regulations. With a spillway width of 6 feet and a hydraulic height of 7 feet, the dam is equipped to handle potential discharge events while maintaining the safety of the surrounding community. The reservoir's primary purpose is listed as "Other," likely encompassing a range of uses from water supply to recreational activities.
Symmes Pond serves as a vital water resource and recreational hub in York, Maine, with its well-maintained dam providing essential storage capabilities. Managed by a private entity, the reservoir offers opportunities for outdoor enthusiasts to enjoy its tranquil waters and scenic surroundings. As climate and water resource enthusiasts, the data on Symmes Pond presents a valuable insight into the infrastructure and management of a key water source in the region, highlighting the importance of sustainable practices and regular maintenance to ensure the safety and longevity of such structures.

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 Symmes Pond
Where does the data for Symmes Pond 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.
