Summary
This dam on Spring Creek serves primarily for flood risk reduction, with a height of 32 feet and a length of 1380 feet. The dam has a storage capacity of 988 acre-feet and a surface area of 45 acres, providing critical protection to the surrounding area.
Although the dam's hazard potential is rated as low, it is designated as a very high-risk site due to its location and the potential consequences of failure. Despite being in operation for over 50 years, the dam's condition assessment is not rated, and the last inspection was conducted in 1980. With state jurisdiction and regulatory oversight from the OWRB, the dam is subject to regular inspections, permitting, and enforcement to ensure its continued safety and efficacy in flood risk management.
As a key infrastructure for managing water resources in the area, SCS-Little Deep Fork Creek Site-12 plays a crucial role in protecting downstream communities from flooding events. With its controlled spillway and valve outlet gates, the dam is equipped to handle maximum discharges of up to 1880 cfs. Despite its age, ongoing risk management measures and regular inspections are essential to maintain the dam's functionality and mitigate potential hazards associated with its operation.

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.
