Snoqualmie Pass Pud Sewage Lagoon No 1 dam
Snoqualmie Pass Pud Sewage Lagoon No 1
Snoqualmie Pass Pud Sewage Lagoon No 1, located in Easton, Washington, is a crucial water resource managed by the Public Utility. This sewage lagoon, also known as Kcsd No. 1, plays a vital role in treating and managing wastewater in the region. The lagoon has been in operation since 1982 and has a storage capacity of 54 acre-feet, with a normal storage level of 22 acre-feet.
The lagoon is regulated by the Washington Department of Ecology and undergoes regular inspections to ensure compliance with state regulations. Despite being classified as a low hazard potential structure, the lagoon serves an essential purpose in maintaining water quality in the area. With a hydraulic height of 23 feet and a structural height of 16 feet, the lagoon covers a surface area of 8.4 acres and has a drainage area of 0.01 square miles.
Overall, Snoqualmie Pass Pud Sewage Lagoon No 1 is a key component of the water infrastructure in Kittitas County, Washington. Its operation and maintenance are vital for protecting water quality in the region and ensuring the proper treatment of wastewater. As a publicly owned facility, the lagoon plays an essential role in environmental stewardship and sustainable water resource management in the area.
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 Snoqualmie Pass Pud Sewage Lagoon No 1
Where does the data for Snoqualmie Pass Pud Sewage Lagoon No 1 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 Low 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.
