Summary
With a height of 27 feet and a storage capacity of 134 acre-feet, this dam plays a key role in protecting the surrounding area from potential flooding events. Despite its low hazard potential, the dam has not been rated for its condition, highlighting the need for regular assessments to ensure its continued functionality.
Managed by the Oklahoma Water Resources Board (OWRB), the SCS-Bitter Creek Site-21 is subject to state regulations, permitting, inspections, and enforcement, demonstrating a commitment to maintaining the safety and integrity of the structure. While the dam has not undergone any modifications in recent years, its risk assessment is categorized as very high, emphasizing the importance of implementing effective risk management measures to mitigate potential hazards. With a controlled spillway and a valve outlet, the dam is equipped to handle maximum discharges of up to 260 cubic feet per second, further enhancing its capacity to manage water flow during periods of high precipitation.
As an essential component of the flood control infrastructure in the region, the SCS-Bitter Creek Site-21 plays a critical role in safeguarding the community of ALEX and its surrounding areas from the impacts of flooding. With its Stone core and Soil foundation, this Earth dam stands as a testament to the collaborative efforts of federal and state agencies in ensuring the resilience of water resources and climate adaptation in the face of evolving environmental challenges.

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.
