Summary
This structure, owned by a public utility, stands at a hydraulic height of 12 feet and a structural height of 10 feet, with a length of 850 feet. The dam has a normal storage capacity of 48 acre-feet, providing essential water resources for the surrounding area.
Managed by the Washington Department of Ecology, Rearing Pond Dike is state-regulated, permitted, inspected, and enforced to ensure its safety and functionality. With a low hazard potential, the dam has not been rated for its condition assessment, but it continues to serve its recreational and environmental purposes effectively. The structure's location in a congressional district represented by Dan Newhouse (R) highlights its significance in water resource management and climate conservation efforts in Washington state.
Despite the lack of recent inspection data and an official condition assessment, Rearing Pond Dike remains a key component of water resource infrastructure in Grant County. With a focus on recreation and supporting fish and wildlife habitats, this earth dam plays a crucial role in water management and environmental conservation in the region. As climate change impacts water resources, structures like Rearing Pond Dike become increasingly important for ensuring sustainable water supply and ecological balance.

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.
