Summary
This earthen dam stands at a height of 12 feet and stretches 265 feet in length, creating a reservoir with a maximum storage capacity of 444 acre-feet. The dam, built on the MIDDLE SPRITE CREEK, serves as a low hazard potential structure with a moderate risk assessment rating.
The dam features an uncontrolled spillway with a width of 30 feet and has not been inspected since January 1, 1980. Despite its condition being labeled as "not rated," the dam continues to provide recreational opportunities and contribute to the surrounding ecosystem. With a drainage area of 2 square miles and a normal storage capacity of 196 acre-feet, the Hillabrandt Vly Dam remains an essential component of water resource management in Fulton County, New York.
While the dam's risk assessment is moderate, there are no specific risk management measures or emergency action plans in place. As a state-owned structure, the New York State Department of Environmental Conservation oversees the regulatory aspects of the dam, ensuring its continued safe operation for recreational purposes. With its strategic location and vital role in water management, the Hillabrandt Vly Dam stands as a reminder of the importance of sustainable water resource practices in the face of changing climates and environmental challenges.

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.
