Lake Triangle Camp Jewell Dam dam
Lake Triangle Camp Jewell Dam
Lake Triangle Camp Jewell Dam, located in Colebrook, Connecticut, is a private dam that was completed in 1952 for the primary purpose of recreation. It impounds the waters of North Brook, creating Lake Triangle Camp Jewell Lake with a storage capacity of 365 acre-feet and a surface area of 50 acres. The dam stands at a height of 10 feet and spans 300 feet in length, with a spillway width of 54 feet and a maximum discharge capacity of 790 cubic feet per second.
This earth dam is regulated by the Connecticut Department of Energy and Environmental Protection (DEEP) and is subject to state permitting, inspection, and enforcement. With a significant hazard potential, the dam has not been officially rated for its condition assessment. The last inspection was conducted in August 2013, with a frequency of every 5 years. While the Emergency Action Plan (EAP) status and risk assessment details are currently unavailable, the dam's location in Litchfield County presents opportunities for water resource and climate enthusiasts to explore and appreciate the ecological significance of this recreational water body.
Overall, Lake Triangle Camp Jewell Dam serves as a vital water resource for the community, offering opportunities for outdoor activities and environmental education. Its presence on North Brook, under the jurisdiction of the New England District of the US Army Corps of Engineers, underscores the importance of maintaining and monitoring dams for both safety and sustainability in the face of changing climate conditions. As stakeholders continue to engage in dam management practices, the conservation and preservation of this picturesque waterway remain essential for future generations to enjoy and appreciate.
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 Lake Triangle Camp Jewell Dam
Where does the data for Lake Triangle Camp Jewell 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.
