Summary
is a privately owned earth dam located in Maud, Oklahoma, within Pottawatomie County. Built in 1971 by the USDA NRCS, this dam is regulated by the Oklahoma Water Resources Board and meets state permitting, inspection, and enforcement requirements. The primary purpose of Mcspadden J.E. is classified as "Other," with a storage capacity of 60 acre-feet and a maximum discharge of 1473 cubic feet per second.
This dam stands at 18 feet in height and stretches 642 feet in length, with a spillway type classified as "Controlled." Despite being rated as "Low" in hazard potential, Mcspadden J.E. is considered to have a "Very High" risk assessment score. The dam features one valve outlet gate and has not been inspected since May 2011, with an inspection frequency of every 5 years. While the condition assessment is marked as "Not Rated," the risk management measures and overall risk characterization of the dam remain unspecified.
Water resource and climate enthusiasts interested in the Mcspadden J.E. dam will find its location along the TR-Little River in Oklahoma's Tulsa District. With its association to the Natural Resources Conservation Service and its stone core foundation on soil, this dam serves as a significant structure within the state's water management infrastructure. Despite its low hazard potential, the high risk assessment highlights potential concerns that may warrant further monitoring and evaluation to ensure the safety and effectiveness of Mcspadden J.E. in managing water resources in the region.

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.
