Summary

Completed in 1940, this earth dam stands at a height of 27 feet and has a length of 730 feet. It has a storage capacity of 540 acre-feet, with a normal storage level of 30 acre-feet. The dam is located on the TR-Tiger Creek within the Tulsa District of the US Army Corps of Engineers.

Tydol's spillway is of the controlled type, with a width of 1 foot. The dam has been assessed as having a low hazard potential, however, it has a very high risk assessment rating. Despite being in a good condition, it has not been rated for its condition assessment. The last inspection of the dam was conducted in August 2011, with a scheduled inspection frequency of 5 years.

Enthusiasts of water resources and climate in Oklahoma may find Tydol an interesting location for recreational activities, given its historical significance and the potential risks associated with its current state. The dam's location in Drumright offers a unique opportunity to explore the surrounding natural environment and appreciate the engineering marvels that support water resource management in the region. With its low hazard potential and high risk assessment rating, Tydol serves as a reminder of the importance of monitoring and maintaining infrastructure to ensure public safety and environmental sustainability in the face of climate challenges.

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.
