Summary

Built in 1953, this earth dam stands at a height of 38 feet and serves primarily for irrigation purposes along the Horse Heaven Creek. With a storage capacity of 750 acre-feet and a drainage area of 5 square miles, the dam plays a crucial role in water resource management in the region.

Managed by the Oregon Water Resources Department, Bonnie View Dam has a significant hazard potential and requires regular inspections, with the last one conducted in October 2018. The dam features a needle outlet gate and does not have a spillway. It is situated in a picturesque location, offering a surface area of 28.1 acres for recreational activities amidst the natural beauty of the surrounding landscape.

For water resource and climate enthusiasts, Bonnie View Dam represents a vital piece of infrastructure with a rich history of serving the agricultural needs of the area. Its presence contributes to the overall water supply management in Crook County and highlights the importance of sustainable water usage practices. With proper maintenance and regulation, this dam continues to play a crucial role in supporting the local ecosystem and economy.

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.
