Turkey Hill Reservoir Dam & Dike dam
Turkey Hill Reservoir Dam & Dike
The Turkey Hill Reservoir Dam & Dike in Middlesex, Connecticut, is a vital piece of infrastructure designed to provide water supply for the region. Owned by a public utility, the dam and dike are regulated by the Connecticut Department of Energy and Environmental Protection (DEEP). The primary purpose of this earth dam is to ensure a steady water supply for the area, with a capacity to store 0 acre-feet of water and covering a surface area of 78 acres.
However, recent inspections have raised concerns about the condition of the dam, with a poor assessment and significant hazard potential. The last inspection in October 2019 highlighted the need for maintenance and repairs to ensure the safety and functionality of the structure. With a spillway width of 100 feet and a height of 10 feet, the Turkey Hill Reservoir Dam & Dike plays a critical role in managing water resources in the area, making it essential to address these maintenance issues promptly.
As climate change continues to impact water resources and infrastructure, the Turkey Hill Reservoir Dam & Dike serves as a reminder of the importance of maintaining and monitoring these structures. With a risk assessment and management measures yet to be fully defined, it is crucial for authorities to prioritize the safety and integrity of this dam to avoid potential hazards and ensure the continued supply of water to the community.
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 Turkey Hill Reservoir Dam & Dike
Where does the data for Turkey Hill Reservoir Dam & Dike 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.
