Summary
The dam, completed in 2009, serves as a Fish and Wildlife Pond on Deadman Creek, with a storage capacity of 129 acre-feet and a surface area of 8.9 acres. It has a controlled spillway and a low hazard potential, making it a crucial habitat for aquatic wildlife in the area.
Despite its low hazard potential, Oknoname 30177 is classified as having a very high risk, possibly due to its structural design or other factors. The dam has a maximum discharge capacity of 129 cubic feet per second, with a hydraulic height of 22.3 feet and a structural height of 29 feet. With regular inspections and enforcement by the state regulatory agency, the dam ensures the safety of the surrounding community and wildlife.
The dam's primary purpose of providing a habitat for fish and wildlife highlights its importance in the local ecosystem. With a drainage area of 1.83 square miles and a normal storage capacity of 56.58 acre-feet, Oknoname 30177 plays a vital role in supporting biodiversity and preserving the natural resources of Tillman County, Oklahoma.

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.
