This dam stands at 22 feet in height and spans 251 feet in length, with a storage capacity of 76 acre-feet and a drainage area of 0.56 square miles. Despite having a low hazard potential, it is classified as having a moderate risk level.
Managed by the Natural Resources Conservation Service, F Schoonmaker features an uncontrolled spillway with a width of 38 feet, capable of handling a maximum discharge of 658 cubic feet per second. The dam serves multiple purposes within the community, although its primary purpose is not specified in the data provided. While it has not been rated for its condition, it is considered to have a moderate risk level, requiring ongoing risk management measures.
As a key component of water resource infrastructure in Oklahoma, F Schoonmaker plays a crucial role in flood control and water storage in the region. With its moderate risk level and low hazard potential, this dam serves as a vital asset for the surrounding area, highlighting the importance of proper maintenance and monitoring to ensure its continued functionality and safety for the community and the environment.

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.
