Summary

Hope Lower, is a significant earth dam located in Scribner Corners, New York. Completed in 1882, this dam has a height of 31 feet and a length of 190 feet, providing storage for up to 70 acre-feet of water. Situated on TR-ONEIDA CREEK, this dam is regulated by the New York State Department of Environmental Conservation (NYS DEC) and is inspected regularly to ensure its structural integrity.

Despite its age, the Lower Reservoir Dam is categorized as having a significant hazard potential with a poor condition assessment. With a drainage area of 2.15 square miles and a surface area of 4 acres, this dam plays a crucial role in water resource management in the area. The spillway type for this dam is uncontrolled, with a spillway width of 17 feet, allowing for controlled release of excess water during times of high flow.

As a key structure in the local government's water management system, the Lower Reservoir Dam is essential for flood control and providing water storage for the surrounding area. With its historical significance and ongoing regulatory oversight, this dam is a vital component of sustainable water resource management in Madison County, New York.

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.
