Summary
This Earth dam, with a height of 35 feet and a length of 432 feet, serves multiple purposes including fish and wildlife pond, recreation, and water supply. With a storage capacity of 69 acre-feet and a drainage area of 275.2 square miles, the dam plays a crucial role in managing water resources in the area.
The dam's primary purpose of creating a fish and wildlife pond is supported by its design features, such as a stone core and a soil foundation. While the dam has a low hazard potential and moderate risk assessment, it is not currently rated for condition assessment. Despite being unregulated by the state and having no inspection frequency listed, the dam provides valuable water storage and recreational opportunities for the community. With a spillway width of 40 feet and a maximum discharge of 161 cubic feet per second, the dam is equipped to handle potential flooding events effectively.
In addition to its structural and operational aspects, Jerald Disney Dam also contributes to the conservation efforts in the region by providing habitat for fish and wildlife. As a key feature in the local landscape, the dam serves as a reminder of the importance of sustainable water resource management and climate resilience. Its location on the TR-Crooked River, within the Rock Island District, highlights the interconnectedness of water infrastructure, environmental protection, and community well-being.

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.
