Summary
is a private earth dam located in Harper, Oklahoma, along the TR-Redoubt Creek. Built in 1960 by USDA NRCS, this dam stands at a height of 26 feet and spans 400 feet in length, with a storage capacity of 430 acre-feet. Despite its low hazard potential and "Not Rated" condition assessment, Freeman Lois F. is state-regulated by the Oklahoma Water Resources Board, with permitting, inspection, and enforcement responsibilities falling under their jurisdiction.
The dam features a controlled spillway with a width of 2 feet and a single valve outlet gate. Although it has not been modified in recent years and lacks an Emergency Action Plan, Freeman Lois F. is designated as a very high risk asset, with a risk assessment score of 1. Given its critical role in water resource management and climate resilience, it is imperative that the dam's condition is regularly monitored and that appropriate risk management measures are implemented to ensure the safety of surrounding communities and ecosystems.
With its connection to the Tulsa District and oversight by the Natural Resources Conservation Service, Freeman Lois F. serves as a vital component of the local water infrastructure. As water resource and climate enthusiasts, it is essential to stay informed about the status of dams like Freeman Lois F. and advocate for proactive measures to address any potential risks and ensure sustainable water management practices in the face of a changing climate.

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.
