Sunheaven Farms Reservoir dam
Sunheaven Farms Reservoir
Sunheaven Farms Reservoir, located in Benton, Washington, is a privately owned irrigation reservoir that draws water from the Columbia River-Offstream. Built in 1986, this Earth-type dam has a hydraulic height of 13 feet and a structural height of 8 feet, with a storage capacity of 100 acre-feet. The reservoir covers a surface area of 9.1 acres and serves the primary purpose of irrigation for agricultural activities in the area.
Managed by the Washington Department of Ecology, Sunheaven Farms Reservoir is regulated and inspected by the state to ensure compliance with safety standards. With a low hazard potential, the reservoir has not been rated for its condition assessment, but it meets the necessary guidelines for emergency action planning. Although the risk assessment and management measures are not specified, the reservoir plays a crucial role in providing water resources for agricultural needs in the region.
Situated in Congressional District 04, Washington, Sunheaven Farms Reservoir stands as a vital infrastructure for water resource management in the area. With its modest size and capacity, the reservoir contributes to sustaining irrigation practices and supporting the agricultural community, highlighting the intersection of water resource management and climate resilience efforts in the region.

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 Sunheaven Farms Reservoir
Where does the data for Sunheaven Farms Reservoir 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.
