Summary
3, located in Spokane, Washington, is a vital water resource managed by the local government for the treatment and storage of wastewater. Built in 1999, this Earth dam stands at a hydraulic height of 23.5 feet, with a maximum storage capacity of 52 acre-feet and a normal storage capacity of 41 acre-feet. The pond is situated off Rock Creek, serving as an important offstream water management facility in the region.
Managed by the Washington Department of Ecology, Rockford Wastewater Pond No. 3 is regulated and inspected regularly to ensure its structural integrity and environmental compliance. With a significant hazard potential but a satisfactory condition assessment as of September 2018, the pond plays a crucial role in water management and wastewater treatment for the surrounding area. As a key component of the local water infrastructure, this facility underscores the importance of sustainable water resource management and climate adaptation in the face of changing environmental conditions.
The pond's Emergency Action Plan (EAP) status and risk management measures are currently under review, highlighting the ongoing efforts to enhance the facility's emergency preparedness and response capabilities. The location's proximity to Rock Creek and its drainage area of 0.01 square miles necessitate careful monitoring and maintenance to prevent potential hazards and ensure the continued safety and reliability of this essential water resource infrastructure. For water resource and climate enthusiasts, Rockford Wastewater Pond No. 3 serves as a notable example of the intersection between water management, infrastructure resilience, and environmental stewardship in the face of a changing climate.

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.
