Bremerton Reservoir No 4 dam
Bremerton Reservoir No 4
Bremerton Reservoir No 4, located in Kitsap, Washington, is a local government-owned dam that serves as a critical water supply source for the region. Completed in 1917, this earth dam stands at a hydraulic height of 13 feet and a structural height of 17 feet, with a storage capacity of 36 acre-feet. The reservoir covers a surface area of 1.2 acres and is situated along the Tr-Puget Sound river/stream.
Maintained by the Washington Department of Ecology, Bremerton Reservoir No 4 has a high hazard potential but is currently in satisfactory condition, based on a recent assessment in August 2018. Emergency action plans are in place, with inspections conducted every 5 years to ensure the dam's safety and integrity. The reservoir is regulated and permitted by the state, showcasing a commitment to water resource management and climate resilience in the face of potential risks and emergencies.
As part of Congressional District 06, Washington, Bremerton Reservoir No 4 plays a vital role in meeting the water supply needs of the community. With its historical significance dating back over a century, the dam continues to be a key asset for water management in the region. Its location and design reflect a balance between water resource utilization and environmental protection, highlighting the importance of sustainable infrastructure for a changing climate landscape.
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.

About Bremerton Reservoir No 4
Where does the data for Bremerton Reservoir No 4 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 High 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.
