Summary
Built in 1961 by the USDA NRCS, this earth dam stands at a height of 19 feet and has a length of 770 feet, providing flood risk reduction for the surrounding area. With a maximum storage capacity of 164 acre-feet and a normal storage of 27 acre-feet, this dam plays a crucial role in managing water resources in Creek County.
Despite being classified as having low hazard potential, SCS-Little Deep Fork Creek Site-27 is considered to have a very high risk level, as indicated by a risk assessment rating of 1. The dam features a controlled spillway and a valve outlet gate, with a spillway width of 1 foot. While the dam's condition assessment is currently listed as "Not Rated," it undergoes inspection every five years, with the last inspection reported in 1980. With the State of Oklahoma taking on ownership and regulatory responsibilities, this dam serves as a significant infrastructure for flood control and water management in the region.
As water resource and climate enthusiasts, the data on SCS-Little Deep Fork Creek Site-27 provides valuable insights into the design, construction, and operation of a key flood risk reduction structure in Oklahoma. This dam not only helps to protect the surrounding area from potential flooding but also highlights the importance of effective water resource management in mitigating natural disasters. With its historical significance and ongoing regulatory oversight, SCS-Little Deep Fork Creek Site-27 serves as a reminder of the critical role that infrastructure plays in safeguarding communities against the impacts of extreme weather events.

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.
