Summary
Constructed in 1964 by the USDA NRCS, this dam stands at a height of 20 feet and spans a length of 670 feet, with a storage capacity of 200 acre-feet. With its primary purpose listed as "Other," this structure is regulated by the Oklahoma Water Resources Board and undergoes regular inspections and enforcement measures to ensure its safe operation.
Despite being classified as having a low hazard potential, Sturdivan No 1 is considered to have a very high risk level, with a risk assessment rating of 1. The dam features a controlled spillway with a width of 1 foot and an outlet gate with a valve. While the condition assessment is listed as "Not Rated," the last inspection was conducted in December 2010 with a frequency of every 5 years. Although emergency action plans and inundation maps are not currently prepared, the dam remains under the jurisdiction of the USDA NRCS and the state regulatory agency, OWRB.
Overall, Sturdivan No 1 serves as a vital infrastructure for water resource management in the Texas County area of Oklahoma, providing essential flood control and water storage capabilities. With its historical significance dating back to the 1960s, this earth dam continues to play a crucial role in the local ecosystem and agricultural practices, highlighting the importance of proper maintenance and regulatory oversight in ensuring its long-term functionality and safety.

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.
