Summary
Built in 1965, this Earth-type dam stands at 23 feet in height and stretches 445 feet in length, with a maximum storage capacity of 60 acre-feet. The dam is regulated by the Oklahoma Water Resources Board (OWRB) and is subject to state inspection, permitting, and enforcement to ensure its structural integrity and compliance with safety regulations.
Despite its low hazard potential, Matherly Jack R poses a very high risk due to its location and potential impact on downstream areas in the event of a breach. The dam has a controlled spillway with a width of 1 foot and is equipped with a valve outlet gate for water release. While it has not been rated for its current condition, the dam undergoes inspections every 5 years to monitor its integrity and safety measures.
Overall, Matherly Jack R serves a primary purpose of "Other" and is classified as a high-risk structure with the potential to cause significant harm if not properly maintained. As a vital water resource in Lincoln County, Oklahoma, this dam highlights the importance of ongoing monitoring and management to mitigate risks associated with aging infrastructure and changing climate conditions.

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.
