Chehalis Regional Water Reclamation Pond dam
Chehalis Regional Water Reclamation Pond
The Chehalis Regional Water Reclamation Pond in Washington is a significant water resource project that plays a crucial role in managing water resources in the region. Designed by Gibbs & Olson, Inc., this earth dam structure sits off the Chehalis River and serves as a reclamation pond for water treatment purposes. Completed in 2005, it has a hydraulic height of 17 feet and a storage capacity of 11 acre-feet, providing essential water storage for the area.
Managed by the Washington Dept of Ecology, this reclamation pond is state-regulated, inspected, and enforced to ensure its structural integrity and operational efficiency. The dam's condition assessment in 2018 deemed it satisfactory, with a significant hazard potential. The pond covers a surface area of 0.83 acres and has a normal storage capacity of 8 acre-feet, contributing to water management and environmental conservation efforts in Lewis County, Washington.
With a strategic location in S30 T14 R2W, the Chehalis Regional Water Reclamation Pond serves as a critical component of the region's water infrastructure. As a local government-owned facility, it underscores the importance of sustainable water resource management and climate resilience. As water resource and climate enthusiasts, the pond's design, construction, and operational details offer valuable insights into how innovative engineering solutions can address water challenges and promote environmental stewardship.
Dam data reference
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.
- 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.
- 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.
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, environmental 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.
Plan around the weather
Same NOAA / yr.no feed Snoflo's iOS app uses. Watch the precipitation column on the meteogram -- rain on the basin upstream typically lifts inflow 24-72 hours later.

About Chehalis Regional Water Reclamation Pond
Where does the data for Chehalis Regional Water Reclamation Pond come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the Significant hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
