Barney dam
Barney
Barney, also known as Es Mills Dam, is a crucial water supply infrastructure located in Tillamook, Oregon. This local government-owned structure was completed in 1998 and serves the M. Fork of North Fork Trask River. With a height of 122 feet and a capacity of 20,000 acre-feet, Barney plays a vital role in water management and supply for the region. The dam's spillway type is uncontrolled, and it has a high hazard potential but is currently assessed as satisfactory.
Situated in Washington County, Oregon, Barney has a structural height of 165 feet and a hydraulic height of 110 feet, with a length of 2500 feet. It covers a surface area of 455 acres and has a maximum discharge capacity of 7780 cfs. The dam's primary purpose is water supply, and it is regulated by the Oregon Water Resources Department. Despite its high hazard potential, Barney is monitored and inspected regularly to ensure its safety and functionality for the community it serves.
Barney's emergency action plan status and risk assessment are currently not available, but the dam is considered to have a moderate risk level. With its role in water supply and management, Barney stands as a crucial piece of infrastructure in the region, providing essential services while being closely monitored for any potential risks or hazards. For water resource and climate enthusiasts, Barney presents an intriguing case study in dam management and water infrastructure in the Pacific Northwest.

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.
Plan around the weather

About Barney
Where does the data for Barney 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.
