Summary
This dam on Quartermaster Creek serves various purposes, with a primary purpose listed as "Other." With a height of 41.1 feet and a storage capacity of 49.2 acre-feet, Leroy Penry plays a crucial role in water resource management in the region.
Owned privately, Leroy Penry is regulated by the Oklahoma Water Resources Board (OWRB) and is subject to state permitting, inspection, and enforcement. Despite its low hazard potential, the dam is considered to have a very high risk due to various factors. With a controlled spillway and a valve outlet, Leroy Penry has a surface area of 9.4 acres and a drainage area of 400 acres, making it a significant feature in the local hydrological landscape.
Water resource and climate enthusiasts will find Leroy Penry a fascinating structure, not only for its design and functionality but also for its role in mitigating flood risks and managing water resources in Roger Mills County, Oklahoma. With its stone core and soil foundation, Leroy Penry stands as a testament to the importance of sustainable water infrastructure in the face of changing climatic 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.
