Higginbotham Reservoir Dam dam
Higginbotham Reservoir Dam
Higginbotham Reservoir Dam, located in Grant County, Washington, was completed in 1947 and serves multiple purposes including irrigation and recreation. The dam, primarily made of earth with a stone core and rock foundation, stands at a hydraulic height of 13 feet and a structural height of 10 feet, creating a reservoir with a normal storage capacity of 145 acre-feet. The dam sits on the Tr-Banks Lake tributary, within the jurisdiction of the Washington Department of Ecology.
With a surface area of 62 acres and a drainage area of 13.75 square miles, Higginbotham Reservoir Dam offers recreational opportunities while also providing vital irrigation water for agricultural activities in the region. Despite its low hazard potential, the dam's condition assessment is currently not rated, highlighting the importance of regular inspections and maintenance to ensure its long-term safety and functionality. As a privately owned structure, the dam is regulated, permitted, inspected, and enforced by state authorities, demonstrating a commitment to responsible water resource management and climate resilience in the area.
The dam's location within Congressional District 04, Washington, under the representation of Dan Newhouse (R), underscores the significance of this infrastructure in the local community. As water resource and climate enthusiasts continue to advocate for sustainable practices and infrastructure resilience, Higginbotham Reservoir Dam serves as a vital asset supporting both human activities and ecosystem health 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 Higginbotham Reservoir Dam
Where does the data for Higginbotham 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.
