About this dam

Tyler Lake Dam

Tyler Lake Dam, located in Goshen, Connecticut, stands as a testament to the region's commitment to water resource management and climate resilience. Built in 1880, this concrete dam serves primarily for recreational purposes, offering a picturesque setting for outdoor enthusiasts to enjoy the surrounding beauty. With a height of 6 feet and a length of 125 feet, the dam provides essential storage capacity of 637 acre-feet, ensuring water availability for various activities.

Managed by the local government and regulated by the Connecticut Department of Energy and Environmental Protection (DEEP), Tyler Lake Dam undergoes regular inspections to maintain its structural integrity and ensure public safety. The dam's hazard potential is classified as significant, emphasizing the importance of ongoing risk assessment and management measures. Despite its age, the dam's condition assessment remains satisfactory, reflecting the dedication to upholding high standards of dam safety in the face of changing climate conditions.

With the Marshepaug River flowing nearby, Tyler Lake Dam plays a vital role in controlling water levels and protecting the surrounding area from potential flooding events. As climate change continues to pose challenges to water resources, this dam stands as a crucial piece of infrastructure that embodies the intersection of environmental stewardship, recreation, and community resilience in the face of a changing world.

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.

FAQ

About Tyler Lake Dam

Where does the data for Tyler 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.
