Scisson Se Reservoir Report
Nearby: Fisher Lake Dam Oknoname 111067
Last Updated: December 6, 2025
Located in McIntosh, Oklahoma, Scisson Se is a privately-owned earth dam with a primary purpose designated as "Other." Standing at 25 feet tall, the dam was completed in 1984 and has a maximum storage capacity of 110 acre-feet.

Summary
With a surface area of 20 acres and a normal storage capacity of 56 acre-feet, the dam regulates the flow of TR-SHELL CR river/stream.
Managed by the Oklahoma Water Resources Board (OWRB), Scisson Se is a state-regulated structure with inspections, permitting, and enforcement all handled by the state agency. The dam has a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment. Despite its low hazard potential, the risk assessment for Scisson Se is considered to be very high, indicating the need for effective risk management measures.
While the dam has not been modified in recent years, it operates with a controlled spillway and a single valve outlet gate. Although the dam is not under the jurisdiction of the U.S. Army Corps of Engineers, it plays a crucial role in water resource management in the region and serves as a key infrastructure for climate and water resource enthusiasts to study and monitor.

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.
