Summary
is a privately owned earth dam located in Coyle, Oklahoma, on the TR-WOLF CREEK. Built in 1965, this dam stands at a height of 25 feet and has a length of 415 feet, with a storage capacity of 60 acre-feet. The dam serves a primary purpose of "Other" and has a spillway width of 1 foot. Despite being rated as having low hazard potential, it is categorized as having a very high risk due to its condition assessment being "Not Rated." The dam is under the regulatory jurisdiction of the Oklahoma Water Resources Board (OWRB) and undergoes regular state inspection, permitting, and enforcement.
With a beautiful surface area of 5 acres, Chappel Mrs C.C. plays a crucial role in water resource management in Logan County, Oklahoma. The dam's design includes a stone core and soil foundation, with a controlled spillway type. It is equipped with a valve outlet gate and has a maximum discharge capacity of 2400 cubic feet per second. The last inspection of the dam was conducted in August 2011, with an inspection frequency of every 5 years. While the dam is currently classified as "Not Rated" in terms of condition assessment, it is important to note the potential risks associated with its very high risk assessment rating.
Chappel Mrs C.C. presents a unique combination of historical significance, environmental impact, and regulatory oversight. As a privately owned structure, it is subject to state jurisdiction and regulation by the OWRB. Its location on TR-WOLF CREEK adds to its importance in managing water resources in the region. With a capacity of 60 acre-feet and a maximum storage volume of 60 acre-feet, this dam plays a crucial role in flood control and water supply management. Despite its low hazard potential, the very high risk assessment underscores the need for ongoing monitoring and maintenance to ensure the safety and integrity of the structure.

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.
