Summary
Constructed in 1962 by the USDA NRCS, this dam stands at a height of 26 feet and has a maximum storage capacity of 110 acre-feet. The dam's primary purpose is listed as "Other," with a low hazard potential and a very high risk assessment rating, indicating the need for careful monitoring and management.
Managed by the Oklahoma Water Resources Board, Owens No.2 is subject to state regulation, permitting, inspection, and enforcement. The dam features a controlled spillway and a single valve outlet gate, with a maximum discharge capacity of 1028 cubic feet per second. Despite its age, the dam's condition remains unrated as of the last inspection in August 2011, highlighting the importance of ongoing maintenance and assessment to ensure its safety and effectiveness in managing water resources in the region.
The dam's location in the Tulsa District and its association with the Natural Resources Conservation Service underscore its role in water resource management and climate resilience efforts. With its proximity to Selman and its crucial role in regulating water flow along the Sand Creek, Owens No.2 serves as a vital infrastructure for water supply, flood control, and environmental protection in Harper County, 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.
