Summary
Managed by local government and state agencies, including the USDA NRCS and NYS DEC, this dam stands at a height of 39 feet and spans 1400 feet, providing a storage capacity of 1778 acre-feet. With a spillway width of 224 feet and a maximum discharge of 7591 cubic feet per second, this dam plays a crucial role in mitigating flood risks in the region.
Despite its essential role in flood control, Conewango Creek Site 13 Dam is considered to have a significant hazard potential, with a moderate risk assessment rating of 3. Regular inspections are carried out, with the most recent conducted in May 2018, and emergency action plans are in place to address any potential risks associated with the dam. The dam's condition is currently not rated, but with proper risk management measures in place, it continues to safeguard the surrounding area from flooding events.
With its strategic location along the Conewango Creek and its vital role in flood risk reduction efforts, Conewango Creek Site 13 Dam stands as a testament to the importance of water resource management and climate resilience. As enthusiasts in water resources and climate, understanding the design, purpose, and management of structures like this dam is crucial for ensuring the safety and sustainability of our communities in the face of changing environmental conditions.

Dam Data Reference
Condition Assessment
SatisfactoryNo 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
HighDams 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.
