Mansfield Recreation Pond dam
Mansfield Recreation Pond
Mansfield Recreation Pond, also known as Bicentennial Pond, is a local government-owned recreational water resource located in Mansfield, Connecticut. Managed by the USDA NRCS, this concrete dam structure on Schoolhouse Brook was completed in 1974 and serves as a popular spot for outdoor activities and leisure. With a dam height of 25 feet and a surface area of 6 acres, the pond offers a serene escape for residents and visitors alike.
The dam's primary purpose is recreation, providing a storage capacity of 67 acre-feet and a drainage area of 0.73 square miles. Despite being categorized as having a significant hazard potential, its condition assessment remains satisfactory as of the last inspection in October 2019. With uncontrolled spillways and outlet gates, the pond offers a moderate risk level for emergencies, with a designated emergency action plan and updated contact information to ensure the safety of those enjoying the recreational amenities it provides.
For water resource and climate enthusiasts, Mansfield Recreation Pond stands as a vital ecological and recreational asset within the Tolland County landscape. Its role in providing outdoor recreational opportunities, water storage capacity, and environmental benefits make it a valuable resource worth preserving and enjoying for generations to come. As a regulated and inspected water feature under the jurisdiction of the Connecticut Department of Energy and Environmental Protection, Mansfield Recreation Pond exemplifies the intersection of human-made infrastructure and natural beauty in harmony with the surrounding ecosystem.
Dam data reference
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 Mansfield Recreation Pond
Where does the data for Mansfield Recreation 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 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.
