Summary

2, located in Shady Grove, Oklahoma, is a crucial water supply infrastructure managed by the local government. This dam, completed in 1924, stands at 48 feet tall and has a storage capacity of 7,781 acre-feet. It serves the primary purpose of providing water supply for the surrounding area, with a normal storage capacity of 2,750 acre-feet.

Situated on the TR-Coal Creek in Pittsburg County, Talawanda No. 2 is regulated by the Oklahoma Water Resources Board (OWRB) and undergoes regular inspections, enforcement, and permitting to ensure its structural integrity and compliance with state regulations. The dam's spillway, with a controlled design and a width of 4 feet, helps manage excess water flow during periods of high discharge.

Despite its low hazard potential, Talawanda No. 2 is identified with a very high risk due to its age and the need for further evaluation and risk management measures. Its importance in providing water resources for the region highlights the significance of ongoing monitoring and maintenance to safeguard its functionality and safety in the face of changing climate conditions.

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.
