Fowler Reservoir Dam dam
Fowler Reservoir Dam
Fowler Reservoir Dam, located in San Juan, Washington, was completed in 1960 and is primarily used for irrigation purposes. This private-owned earth dam stands at a hydraulic height of 15 feet and has a structural height of 13 feet, with a length of 545 feet. With a maximum storage capacity of 70 acre-feet and a normal storage capacity of 42 acre-feet, this dam plays a crucial role in providing water for irrigation, fire protection, stock, small fish ponds, and recreational activities in the area.
Managed by the Washington Department of Ecology, Fowler Reservoir Dam is regulated, permitted, inspected, and enforced by the state. Despite its low hazard potential, the dam has not been rated for its condition assessment, and there is limited information available on its emergency action plan, risk assessment, and risk management measures. The dam overlooks Tr-East Sound and has a drainage area of 0.7 square miles, with a surface area of 9 acres. While the dam has not been modified in recent years, it continues to serve its purpose in maintaining water resources for the surrounding community.
Represented in Congressional District 02 by Rick Larsen (D), Fowler Reservoir Dam is a vital infrastructure for water resource management in the region. Although its condition assessment remains unrated, the dam's low hazard potential and consistent state regulation suggest a reliable structure that contributes to the local water supply and ecosystem. As a key component for irrigation and other purposes, Fowler Reservoir Dam stands as a testament to the importance of sustainable water management practices in the face of changing climate conditions.
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 Fowler Reservoir Dam
Where does the data for Fowler Reservoir Dam 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.
