Woolfolk Reservoir dam
Woolfolk Reservoir
Woolfolk Reservoir, located in Brownsboro, Oregon, is a privately owned earth dam constructed in 1955 primarily for irrigation purposes. Situated on School House Creek, this reservoir has a storage capacity of 700 acre-feet, with a normal storage level of 480 acre-feet and a surface area of 34 acres. The dam stands at 47 feet in height, with a hydraulic height of 45 feet and a structural height of 49 feet.
With a significant hazard potential, Woolfolk Reservoir is regulated by the Oregon Water Resources Department and undergoes regular inspections, with the last one conducted in December 2020. Its outlet gates consist of a slide (sluice gate), and the maximum discharge capacity reaches 1862 cubic feet per second. The reservoir serves as a vital water resource for the surrounding area, supporting agricultural practices and contributing to the local ecosystem's sustainability.
Enthusiasts of water resources and climate will find Woolfolk Reservoir to be a crucial component of the region's water management infrastructure. As a key source of irrigation water, this reservoir plays a vital role in supporting agricultural activities in Jackson County, Oregon. With its regulated status and regular inspections, Woolfolk Reservoir demonstrates a commitment to safety and efficiency in water resource management, ensuring sustainable water usage for the community and surrounding environment.

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 Woolfolk Reservoir
Where does the data for Woolfolk 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 Significant 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.
