Summary
Built in 1951, this earth dam with a height of 12 feet and a length of 480 feet provides a storage capacity of 20 acre-feet, with a normal storage level of 12 acre-feet. Despite its functional significance, the dam is classified as having a high hazard potential and a poor condition assessment, as of the last inspection in August 2019.
Managed by the Washington Department of Ecology, the Haight Reservoir Dam is subject to state regulation, inspection, and enforcement, ensuring its safety and compliance with guidelines. The surrounding area boasts a surface area of 3 acres and a drainage area of 0.02 square miles, with a maximum discharge capacity of 21 cubic feet per second. Although no spillway type or width is specified, the dam remains a key feature in the local landscape, serving as a vital water resource for the community.
Despite its age and condition, the Haight Reservoir Dam continues to play a crucial role in supporting irrigation activities and recreational opportunities in the region. As efforts are made to address its poor condition and high hazard potential, the dam remains a testament to the importance of water resource management and climate resilience in safeguarding our infrastructure for future generations.

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.
