Van Wingerden Pond 1 Reservoir Report
Last Updated: March 3, 2026
Van Wingerden Pond 1, located in Yakima, Washington, is a private water resource primarily used for recreation and irrigation purposes.
Summary
The dam, completed in 1980, stands at a hydraulic height of 18 feet and a length of 650 feet, providing a storage capacity of 94 acre-feet. The pond is regulated by the Washington Department of Ecology and undergoes regular inspections to ensure its structural integrity.
Despite its low hazard potential and fair condition assessment, Van Wingerden Pond 1 remains a key water source in the region. The dam's earth structure and associated infrastructure have not been modified since its completion, reflecting the stability of the site. The pond's location within the Seattle District and under Congressional District 04 further underscores its importance in the water management and conservation efforts in the area.
With its picturesque setting and vital role in supporting local agriculture and recreational activities, Van Wingerden Pond 1 serves as a valuable asset to the community. As climate change continues to impact water resources, the maintenance and regulation of such structures are crucial for ensuring a sustainable and resilient water supply for future generations.

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.
