Summary
With a height of 42 feet and a length of 1730 feet, this dam plays a vital role in controlling the flow of Mission Creek-TR during periods of heavy rainfall. The dam has a storage capacity of 469.8 acre-feet and covers a surface area of 10.69 acres, serving a drainage area of 1.1 square miles.
Despite its importance in flood risk management, Frd No 5b has a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment. The dam features an uncontrolled spillway with a width of 40 feet and no outlet gates. While the risk assessment for the dam is considered moderate, there is no Emergency Action Plan (EAP) in place, and the last inspection date is unknown. With its crucial role in mitigating flood risks in the Mission Creek watershed, ongoing monitoring and maintenance of Frd No 5b are essential to ensure its continued effectiveness and safety for the community of Oketo and surrounding areas.

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.
