Jenkins Webley Dam dam
Jenkins Webley Dam
Jenkins Webley Dam, located in Bridgeport, Washington, is a privately owned structure regulated by the Washington Department of Ecology. Completed in 1945, this earth dam serves primarily for irrigation purposes along the Tr-Columbia River. With a height of 15 feet and a length of 218 feet, the dam has a normal storage capacity of 586 acre-feet and a maximum storage of 1200 acre-feet, ensuring water availability for agricultural activities in the region.
The low hazard potential of Jenkins Webley Dam is complemented by its multi-arch core type design, which utilizes rock and soil foundations for structural stability. The dam's maximum discharge capacity of 254 cubic feet per second ensures effective flood control measures in the area. While the dam's condition remains unrated, its compliance with state inspection and regulatory guidelines reflects a commitment to safety and operational efficiency in managing water resources for irrigation within the region.
Congressional District 04's representative, Dan Newhouse, oversees the management of Jenkins Webley Dam, ensuring that emergency action plans are in place to address any potential risks. While the dam's condition assessment is pending, its strategic location and operational capabilities contribute to the sustainable utilization of water resources for agricultural needs in Douglas County, Washington. As a vital component in the local irrigation infrastructure, Jenkins Webley Dam exemplifies the importance of effective water management practices in sustaining agricultural productivity 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 Jenkins Webley Dam
Where does the data for Jenkins Webley 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.
