Summary
Constructed in 1908, this private-owned earth dam stands at a height of 22 feet, with a storage capacity of 250 acre-feet. The dam's primary purpose is to support irrigation activities in the area, with a normal storage capacity of 206 acre-feet and a maximum discharge of 45 cubic feet per second.
Despite its low hazard potential, Bennett Dam is regulated and inspected by the Oregon Water Resources Department to ensure its structural integrity and safety. The dam features slide (sluice gate) outlet gates and has a surface area of 23.6 acres, serving as a vital resource for water management in the region. The dam's last inspection was conducted in October 2018, with an inspection frequency of six years, and its condition assessment is currently marked as "Not Rated."
As a key component of the local water infrastructure, Bennett Dam plays a crucial role in supporting agricultural activities and water supply in Baker, Oregon. Its strategic location and design make it an essential asset for managing water resources in the area, showcasing the importance of sustainable water management practices in the face of climate change challenges.

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.
