Summary
Completed in 1917, this earth dam stands at a height of 12 feet, with a storage capacity of 265 acre-feet and a surface area of 6.5 acres. Fed by Butte Creek, this reservoir plays a crucial role in supporting agricultural activities in the region, with a low hazard potential and no current condition assessment.
Despite its modest size, Copeland Reservoir plays a significant role in the local water management system, providing essential irrigation water to the surrounding area. With full state regulation and oversight from the Oregon Water Resources Department, the reservoir ensures water availability for agricultural needs while also serving as a potential resource for climate resilience efforts in the region. The dam's primary purpose of irrigation highlights its importance in sustaining agricultural production and supporting local communities.
Located in an area with no downstream settlement, Copeland Reservoir represents a key infrastructure asset managed by the federal government. With a history dating back over a century, this reservoir continues to contribute to the region's water resource management efforts, showcasing the intersection of water infrastructure, climate adaptation, and agricultural sustainability in the unique landscape of Malheur, Oregon.

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.
