Summary
Built in 1950, this Earth-type dam stands at a height of 30 feet and spans a length of 345 feet along TR-ROWLAND CREEK. Managed by the Oklahoma Water Resources Board, this dam is regulated, inspected, and enforced by the state, ensuring its safety and compliance with standards. With a low hazard potential and a very high risk assessment rating, this dam is equipped with a controlled spillway and a single valve outlet gate.
Despite not being rated for its condition assessment, Oknoname 037045 has a NID storage capacity of 50 acre-feet and a maximum discharge rate of 1100 cubic feet per second. While the dam is not owned or funded by any federal agencies, it serves a primary purpose of "Other" and is classified as a very high-risk structure. The dam's emergency action plan status, inundation maps, and risk management measures are not currently updated or prepared, highlighting the importance of ongoing monitoring and maintenance to ensure the safety of the surrounding community and water resources.

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.
