Summary

The dam is made of concrete, stands at a height of 34 feet, and has a length of 410 feet. It impounds Doodletown Brook and has a storage capacity of 36 acre-feet, with a normal storage level of 20 acre-feet.

Despite its important role in the region, Doodletown Dam has been assessed as being in poor condition, with a significant hazard potential. The dam has an uncontrolled spillway with a width of 88 feet and has been subject to inspections every four years. The last inspection in November 2017 revealed the dam's poor condition, prompting concerns about its safety and the potential risks it poses to the surrounding area.

Efforts are being made to manage the risks associated with Doodletown Dam, with a moderate risk assessment rating given. The New York State Department of Environmental Conservation is responsible for regulating and inspecting the dam to ensure its safe operation. Despite its current challenges, Doodletown Dam remains a vital piece of infrastructure for both recreation and water supply in the region.

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.
