Summary
The dam, situated on the South Fork Calvary Creek, stands at a height of 37.3 feet and has a length of 469 feet, with a storage capacity of 25.98 acre-feet and a drainage area of 140 acres. Designed for purposes beyond flood control or water supply, this dam serves as a vital infrastructure for managing water resources in the region.
Despite being classified as having a low hazard potential, Dale Folks Gss #1 is deemed to have a very high risk level, with a risk assessment rating of 1. The condition assessment of the dam is currently not rated, and there is no information available regarding the emergency action plan or risk management measures in place. With state regulatory agencies like the OWRB overseeing its operations, inspections, and enforcement, this dam plays a crucial role in ensuring the safety and sustainability of water resources in the area.
As a focal point for water resource and climate enthusiasts, Dale Folks Gss #1 stands as a testament to the collaborative efforts of various agencies in managing and maintaining essential water infrastructure in Oklahoma. With its controlled spillway, it serves as a critical component in flood control and water management, highlighting the importance of sustainable practices in safeguarding our natural resources for future generations.

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.
