Summary

Built in 1958, this Earth type dam serves primarily for irrigation purposes, with a storage capacity of 20 acre-feet and a normal storage level of 19.7 acre-feet. The reservoir covers a surface area of 2.4 acres and is situated on an unnamed tributary to Coyote Creek. With a structural height of 20 feet and a hydraulic height of 14 feet, Schwartz Reservoir plays a significant role in water management in the region.

Managed by the Oregon Water Resources Department, Schwartz Reservoir is subject to state regulations, inspections, and enforcement to ensure its safety and functionality. The dam features a slide (sluice gate) outlet gate for water release and has a hazard potential classified as 'Significant'. The last inspection was conducted in August 2018 with a frequency of every 3 years. While the condition assessment is marked as 'Not Rated', the dam's emergency action plan status, risk assessment, and management measures are currently listed as unavailable, indicating a potential area for improvement in emergency preparedness and risk mitigation strategies.

Located in a remote area with no downstream settlements, Schwartz Reservoir stands as a vital infrastructure for agricultural irrigation in the region. With its historical significance dating back to the mid-20th century, the dam continues to play a crucial role in water resource management and serves as a testament to the importance of sustainable water practices in the face of changing climate conditions.

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. 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

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, 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.
