Summary

and regulated by the Washington Department of Ecology. Completed in 2008, this earth dam stands at a hydraulic height of 13.5 feet and serves the primary purpose of flood risk reduction. With a normal storage capacity of 21.6 acre-feet and a maximum discharge of 400 cubic feet per second, this structure plays a vital role in managing water resources in the area.

The Redmond Ridge East Pond Srn 2 No 1 covers a surface area of 6 acres and has a drainage area of 0.17 square miles. Despite being categorized as having a high hazard potential, the structure is assessed to be in fair condition as of June 2016. Regular inspections and enforcement by state regulatory agencies ensure its continued functionality and safety for the surrounding community. With a storage capacity of 52 acre-feet and a strategic location in S34 T26 R6E, this dam plays a critical role in protecting the area from potential flooding events.

As climate change continues to impact weather patterns and water resources, structures like the Redmond Ridge East Pond Srn 2 No 1 become increasingly important for managing flood risks and ensuring water security. With a focus on flood risk reduction and a track record of state permitting and inspection, this dam serves as a key component of the water infrastructure in Washington State. As water resource and climate enthusiasts, staying informed about the condition and functionality of such structures is essential for effective water management and climate resilience efforts.

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.
