Summary
Built in 1965, this earth dam stands at a height of 18 feet and has a hydraulic height of the same measurement, providing a storage capacity of 80 acre-feet for irrigation and recreation purposes. Situated on the Tr-Ringwood Lake tributary, the dam covers a surface area of 23 acres and has a drainage area of 8 square miles.
Managed by the Washington Department of Ecology, Brown Dam has a low hazard potential and has not been rated for its condition as of yet. Despite this, the dam has not been inspected since August 1998, raising concerns about its current state and the potential risks it may pose. With a maximum discharge of 160 cubic feet per second, stakeholders and enthusiasts in water resource and climate conservation should push for regular inspections and maintenance to ensure the safety and longevity of this essential infrastructure.
Although primarily used for recreation, Brown Dam also serves as a vital source of irrigation water for the surrounding areas. With its proximity to Congressional District 05 and the oversight of Representative Cathy McMorris Rodgers, it is crucial for the dam to undergo regular assessments and be brought up to current safety standards to prevent any potential disasters. Enthusiasts should advocate for increased monitoring and funding to ensure the sustainability and resilience of this important water resource in Lincoln County.

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.
