Buck Mountain Reservoir Dam No 2 dam
Buck Mountain Reservoir Dam No 2
Buck Mountain Reservoir Dam No 2, located in East Sound, San Juan County, Washington, was completed in 1985 and serves as a vital water supply source for the surrounding area. The dam, primarily owned by a private entity, stands at a hydraulic height of 31 feet, with a structural height of 27 feet and a length of 140 feet. The reservoir has a storage capacity of 156 acre-feet, with a normal storage level of 121 acre-feet and a surface area of 10.5 acres.
Managed by the Washington Department of Ecology, this earth dam with a stone core is designed to withstand high hazard potential and has been assessed to be in fair condition as of June 2019. The dam is regularly inspected, with the last inspection conducted in June 2018, and has emergency action plans in place to ensure the safety of the surrounding communities in case of any unforeseen events. With a drainage area of 0.57 square miles and a maximum discharge capacity of 365 cubic feet per second, Buck Mountain Reservoir Dam No 2 plays a crucial role in water resource management in the region.
This dam, situated in Congressional District 02 of Washington, is a key component of the local water infrastructure, providing essential water supply for the residents of East Sound and beyond. With its regulated status by the state and adherence to inspection and enforcement protocols, Buck Mountain Reservoir Dam No 2 stands as a reliable and necessary structure for ensuring water security in the area. Climate and water resource enthusiasts will find interest in the design and operational details of this significant dam, contributing to the conservation and sustainable use of water resources in Washington State.
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 Buck Mountain Reservoir Dam No 2
Where does the data for Buck Mountain Reservoir Dam No 2 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.
