Summary

Built in 2005 by the USDA NRCS, this Earth-type dam serves as a Fish and Wildlife Pond, with a primary purpose of providing habitat for aquatic life. With a dam height of 16.1 feet and a storage capacity of 110 acre-feet, this structure covers a surface area of 25.7 acres and has a drainage area of 118 square miles.

Managed by the Oklahoma Water Resources Board, Oknoname 30195 is equipped with a controlled spillway and one valve outlet gate. Despite its low hazard potential, this dam has a very high risk assessment rating due to its location and potential impact on the surrounding area in the event of a breach. Regular inspections are conducted every 5 years to ensure the structural integrity and safety of the dam, with the last inspection taking place in February 2010.

Overall, Oknoname 30195 plays a crucial role in supporting local wildlife and maintaining water resources in the region. With its strategic design and regulatory oversight, this dam serves as a key asset for conservation efforts in the Poteau River area, highlighting the importance of sustainable water management practices for both environmental and recreational purposes.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
