Summary
Owned privately, this Earth dam structure boasts a height of 38.5 feet, providing a storage capacity of 97 acre-feet with a maximum discharge capability of 130 cubic feet per second. A key feature of the reservoir is its association with the East Dairy Creek, tributary to the region, highlighting its significance in water management.
With a surface area of 7.95 acres and a drainage area of 0.15 square miles, Bump Farm Reservoir plays a crucial role in water supply management in the region. Regulated and inspected by the Oregon Water Resources Department, the reservoir's low hazard potential and unassessed condition point towards its stable and secure functioning. Additionally, its location within the Portland District underlines its strategic importance in the local water infrastructure network, contributing to sustainable agricultural practices in the area.
As water resource and climate enthusiasts delve into the details of Bump Farm Reservoir, its historical significance, operational parameters, and regulatory framework offer a fascinating insight into the intersection of human intervention and natural ecosystems. With Suzanne Bonamici representing the region in Congress, the reservoir's role in supporting irrigation activities underscores the delicate balance between water utilization and conservation efforts in the ever-changing landscape of Washington and Oregon. A symbol of effective water management, Bump Farm Reservoir stands as a testament to the collaborative efforts towards sustainable resource utilization in the region.

Dam Data Reference
Condition Assessment
SatisfactoryNo 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. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
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. Investigations and studies are necessary.
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.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams 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, environment 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.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
