Summary

Completed in 1973, this earth dam stands at a height of 16 feet and stretches 600 feet in length, with a storage capacity of 51 acre-feet. Situated on the TR-W Branch Delaware River, the dam boasts a spillway width of 8 feet and a maximum discharge of 125 cubic feet per second.

Owned by a private entity, the dam is regulated by the New York State Department of Environmental Conservation (NYS DEC), with state permitting, inspection, and enforcement in place. Despite a low hazard potential, the dam's condition assessment is currently not rated, with the last inspection conducted in May 2014. In terms of risk management, the dam falls under a moderate risk category, with certain risk assessment measures in place.

Water resource and climate enthusiasts will find T Bertram Anderson Dam to be an intriguing structure, not just for its recreational significance but also for its environmental impact and regulatory oversight. With its location in the picturesque Delaware County, New York, this dam serves as a vital part of the local water infrastructure while also offering opportunities for outdoor activities and leisure.

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. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
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. Investigations and studies are necessary.
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.
Not Available
Dams for which the condition assessment is restricted to approved government users.

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, environment 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.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
