Enloe Dam dam
Enloe Dam
Enloe Dam, located on the Similkameen River in Oroville, Washington, was completed in 1920 and stands at a structural height of 57 feet, with a hydraulic height of 63 feet. The dam serves primarily for recreational purposes, offering a surface area of 2400 acres and a drainage area of 3590 acres. Enloe Dam is a concrete structure with a core type of Multi-Arch and rests on a rock foundation. Despite its age, the dam is in fair condition as of the last assessment in June 2020.
With a maximum storage capacity of 2400 acre-feet and a maximum discharge rate of 46,000 cubic feet per second, Enloe Dam plays a crucial role in water resource management in the region. However, due to its high hazard potential, the dam is closely regulated by the Washington Department of Ecology, with state permitting, inspection, and enforcement measures in place. Although the last inspection took place in May 1986, the dam undergoes regular assessments every 5 years to ensure its structural integrity and safety for surrounding communities.
Enloe Dam is situated in a picturesque setting and offers opportunities for outdoor recreation, making it a popular destination for water resource and climate enthusiasts. The dam's location in Okanogan County, Washington, provides a serene backdrop for activities such as boating, fishing, and hiking. As efforts continue to maintain the dam's safety and functionality, Enloe Dam remains a key feature in the region's water infrastructure, serving both practical and recreational purposes for residents and visitors alike.

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 Enloe Dam
Where does the data for Enloe 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 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.
