Summary
Completed in 1969, this earth dam stands at 22 feet high with a hydraulic height of 20 feet and a length of 615 feet, providing a normal storage capacity of 22 acre-feet and a maximum storage of 50 acre-feet. Despite being classified as low hazard potential, the risk assessment for this site indicates a very high risk level, making it a critical infrastructure for flood management in the region.
Managed by the OWRB, this dam is equipped with a controlled spillway and a single valve outlet gate for water release. Though last inspected in 1980 with an inspection frequency of 5 years, the structure's condition assessment remains unrated. The site also lacks an emergency action plan and updated contact information, highlighting a need for improved risk management measures. With a risk management summary yet to be established, it is crucial for stakeholders to prioritize the safety and maintenance of this dam to mitigate potential hazards and ensure its effectiveness in flood control efforts for the surrounding area.

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.
