Summary
Built in 1960 by the USDA NRCS, this earth dam stands at a height of 36 feet and stretches 1280 feet in length. With a primary purpose of flood risk reduction, it provides a storage capacity of 1785 acre-feet and a maximum discharge of 3925 cubic feet per second.
Despite being classified as having a low hazard potential, the risk assessment for SCS-Little Deep Fork Creek Site-48 indicates a very high risk level. The dam is equipped with a controlled spillway and a single valve outlet gate. While its condition assessment is marked as "Not Rated," the dam has not undergone inspection since January 1980. With the dam falling under state jurisdiction and regulation by the OWRB, the site serves as a crucial infrastructure for managing water resources and mitigating flood risks in the region.
Water resource and climate enthusiasts will find SCS-Little Deep Fork Creek Site-48 to be an intriguing case study in dam engineering and risk management. This dam not only plays a vital role in flood risk reduction but also highlights the importance of regular inspection and maintenance to ensure the safety and efficiency of water infrastructure. With its historical significance and unique design features, this site offers valuable insights into the intersection of water management, environmental conservation, and public safety.

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.
