Summary

Classified as a private dam with a primary purpose of recreation, this earth dam boasts a height of 21 feet and a length of 600 feet. With a storage capacity of 91 acre-feet and a surface area of 13 acres, the dam plays a crucial role in maintaining the water levels of the TR-WEST BR DELAWARE RIVER.

Despite its recreational significance, the Deposit Reservoir Dam poses a significant hazard potential and has been assessed as being in poor condition. With a moderate risk level and a history of poor condition assessment, the dam requires regular inspections and maintenance to ensure its structural integrity and prevent any potential emergencies. The dam, regulated by the NYS DEC, is subject to state permitting, inspection, and enforcement.

Water resource and climate enthusiasts will find the Deposit Reservoir Dam to be a compelling case study in the management of private dams for recreational purposes. Its location in Broome, New York, and its association with the TR-WEST BR DELAWARE RIVER make it a focal point for understanding the intersection of human activity, water resources, and environmental conservation. With its history, condition, and risk assessment in focus, the dam serves as a reminder of the importance of diligence in maintaining critical infrastructure for both recreational enjoyment and public safety.

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.
