Summary
Completed in 1961, this earth dam stands at a height of 20 feet and stretches 720 feet in length, with a capacity for 99 acre-feet of storage. The dam features a controlled spillway and a single valve outlet gate.
Despite being classified as having a low hazard potential, the risk assessment for SCS-Little Deep Fork Creek Site-20 indicates a very high risk level. However, the condition of the dam is currently not rated, and the last inspection was conducted in 1980. With a 5-year inspection frequency, there is room for improvement in maintaining the structure's safety and functionality. The dam's emergency action plan status, inundation maps, and risk management measures also appear to be lacking critical updates and documentation.
Water resource and climate enthusiasts interested in the management and maintenance of dams like SCS-Little Deep Fork Creek Site-20 may find this site's data intriguing. The need for regular inspections, updated emergency plans, and risk assessments highlights the importance of ongoing monitoring and care for critical infrastructure in flood-prone areas.

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.
