Summary
This dam, situated along the Subsidiary Sandy Creek, serves a unique purpose and has a low hazard potential. With a structural height of 23 feet and a storage capacity of 98.5 acre-feet, Oknoname 30169 plays a crucial role in managing water resources in the region.
Managed by the Oklahoma Water Resources Board, this dam is equipped with a controlled spillway and a single valve outlet gate. Despite being classified as a low hazard structure, it poses a very high risk due to its condition assessment not being rated. With a drainage area of 368 square miles and a normal storage capacity of 37.7 acre-feet, Oknoname 30169 is an integral part of the water infrastructure in Ada, Oklahoma.
Although last inspected in 2010, this dam is subject to regular inspections every five years to ensure its structural integrity and safety. With its unique design and purpose, Oknoname 30169 represents a vital component of water resource management in the region, highlighting the importance of maintaining and monitoring such infrastructure for climate resilience and water security.

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.
