Bashan Lake Dam dam
Bashan Lake Dam
Bashan Lake Dam, located in East Haddam, Connecticut, is a picturesque masonry dam situated on the Moodus River. Built in 1939, this state-regulated structure serves primarily for recreational purposes, offering a serene environment for water resource and climate enthusiasts to enjoy. With a height of 24 feet and a length of 170 feet, the dam has a storage capacity of 4,890 acre-feet, providing ample water for its 267-acre surface area.
Managed by the Connecticut Department of Energy and Environmental Protection (DEEP), Bashan Lake Dam has a significant hazard potential and is inspected every five years to ensure its safety and integrity. The dam's spillway width of 29 feet allows for a maximum discharge of 165 cubic feet per second, reducing the risk of flooding during heavy rain events. While the dam's condition assessment is currently not rated, emergency action plans have been prepared and updated to meet guidelines, ensuring swift response in case of any unforeseen events.
Situated in Middlesex County, Connecticut, Bashan Lake Dam stands as a testament to the importance of responsible water resource management in the face of changing climate conditions. With its rich history, recreational opportunities, and commitment to safety, this dam is a vital asset to the community and a beacon for those passionate about preserving our water resources for future generations.
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 Bashan Lake Dam
Where does the data for Bashan Lake 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.
