Frye Lake Dam dam
Frye Lake Dam
Frye Lake Dam in Greenwich, Connecticut, is a privately owned structure built in 1930 primarily for recreational purposes. Situated on Greenwich Creek, this earth dam stands at 10 feet high and spans a length of 280 feet, with a storage capacity of 40.5 acre-feet. The dam's normal storage level is 15.2 acre-feet, covering a surface area of 12 acres and serving a drainage area of 0.55 square miles.
Despite its age, Frye Lake Dam has been deemed to be in satisfactory condition during its last inspection in April 2017, with a significant hazard potential. The dam is regulated by the Connecticut Department of Energy and Environmental Protection (DEEP), which conducts regular inspections and enforces safety measures. The dam's emergency action plan (EAP) was last revised in March 2017, ensuring that proper guidelines are in place for emergency situations.
Water resource and climate enthusiasts interested in Frye Lake Dam will appreciate its historical significance and recreational value, as well as the ongoing efforts to maintain its safety and integrity. With its picturesque location and vital role in managing water levels on Greenwich Creek, Frye Lake Dam represents a harmonious blend of human engineering and environmental stewardship in the beautiful landscape of Fairfield County, Connecticut.

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 Frye Lake Dam
Where does the data for Frye 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.
