Summary
Jr. is a state-regulated dam located in Stonewall, Oklahoma, on the TR-North Fork Jack FK CR river. Built in 1964, this earth dam stands at a height of 15 feet and has a maximum storage capacity of 53 acre-feet. With a controlled spillway and one valve outlet gate, this dam serves a primary purpose of "Other" and is designated as having a low hazard potential. Despite its age, Little W.D. Jr. remains in good condition and has not been rated for its current state.
Owned by the state of Oklahoma, Little W.D. Jr. is subject to state jurisdiction, permitting, inspection, and enforcement by the Oklahoma Water Resources Board (OWRB). The dam is situated in Pontotoc County and falls under the oversight of the Tulsa District of the US Army Corps of Engineers. Although the dam has not undergone any modifications in recent years, it has a designated inspection frequency of 5 years. With a risk assessment rating of "Very High (1)", measures for risk management and emergency preparedness are crucial for the continued safety of this structure.
Water resource and climate enthusiasts will appreciate the strategic location and design features of Little W.D. Jr. The dam's importance in water storage and regulation, as well as its role in mitigating potential hazards, underscores the significance of maintaining and monitoring such infrastructure. With its historical significance dating back to the 1960s, this earth dam stands as a testament to the ongoing efforts to manage water resources effectively in Oklahoma.

Dam Data Reference
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.
