Summary
Built in 1962 by the USDA NRCS, this structure serves as a water supply source with a storage capacity of 70 acre-feet. The dam stands at 20 feet in height and stretches 427 feet in length, with a spillway type classified as "Controlled" and a maximum discharge rate of 740 cubic feet per second.
Despite its low hazard potential, Xit No.8 is regulated by the Oklahoma Water Resources Board and undergoes regular inspection and enforcement to ensure its structural integrity and safety. The dam is equipped with a single valve outlet gate and has a very high risk assessment ranking of 1, indicating the importance of proper risk management measures. Although the condition assessment is currently rated as "Not Rated," the structure's risk level highlights the need for ongoing monitoring and emergency preparedness.
While Xit No.8 has not been modified in recent years and lacks certain emergency management protocols like an Emergency Action Plan (EAP), its critical role in water supply underscores the importance of maintaining and monitoring this infrastructure. As climate change continues to impact water resources, structures like Xit No.8 play a vital role in ensuring a reliable water supply for the community and surrounding areas. With its unique design and history, Xit No.8 stands as a testament to the interplay between water resource management and climate resilience in Oklahoma.

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.
