Summary

With a structural height of 25 feet and a storage capacity of 134 acre-feet, this dam serves a primary purpose of "Other" and has a low hazard potential. Despite not being regulated or inspected by the state, Beisley Lake Dam-South plays a crucial role in regulating water flow along TR-BROAD WATERS MUDDY CREEK.

This dam, managed by the Tulsa District of the US Army Corps of Engineers, is situated in a rural area with a drainage area of 170 square miles. The reservoir created by Beisley Lake Dam-South has a normal storage capacity of 83 acre-feet and covers a surface area of 10 acres. While the dam is not currently rated for condition assessment, its low hazard potential suggests that it poses minimal risk to surrounding communities.

Although Beisley Lake Dam-South does not have an Emergency Action Plan (EAP) in place or updated contact information for emergency situations, its strategic location and design contribute to water resource management and environmental conservation efforts in the region. For water resource and climate enthusiasts, this dam serves as a reminder of the importance of maintaining and monitoring critical infrastructure to ensure the safety and sustainability of our water systems.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
