Summary

Completed in 1964, this rockfill dam stands at a hydraulic height of 60 feet, with a structural height of 55 feet and a length of 250 feet. The primary purpose of this dam is for recreation, with a storage capacity of 120 acre-feet and a normal storage level of 102 acre-feet.

Managed by the Washington Department of Ecology, Camp Kwoneesum Dam is state regulated and inspected, with enforcement measures in place to ensure its safety and compliance with regulations. With a high hazard potential but a satisfactory condition assessment as of February 2020, this dam plays a crucial role in the management of the Wildboy Creek Tr-Washougal River system. The dam's location in Congressional District 03, Washington, under the representation of Jaime Herrera Beutler, further highlights its significance in the region.

Water resource and climate enthusiasts can appreciate the engineering and recreational aspects of Camp Kwoneesum Dam, as well as its role in providing vital storage and flow regulation for the surrounding area. The dam's historical significance, along with its risk management measures and inspection frequency, showcase the commitment to maintaining its integrity while ensuring public safety. As a key component of the water infrastructure in Skamania, Washington, this rockfill dam stands as a testament to the balance between human recreation and environmental stewardship 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.
