Summary
Completed in 1940, this Earth-type structure stands at a height of 22 feet with a length of 600 feet, providing a storage capacity of 50 acre-feet. The dam, situated on the TR-SNAKE CR river or stream, features a controlled spillway and a single valve outlet gate.
Despite its low hazard potential, Oknoname 111028 is classified as having a very high risk due to its age and condition assessment being labeled as "Not Rated." The last inspection in August 2011 revealed a 5-year inspection frequency. The dam's emergency action plan status, inundation maps, and risk management measures are currently unspecified. With state jurisdiction and regulation in place, this structure serves a primary purpose of "Other" and poses a potential risk to the surrounding area in case of failure.
For water resource and climate enthusiasts, Oknoname 111028 presents an intriguing case study in dam infrastructure management and risk assessment. With its historical significance dating back to the 1940s and a mix of state and private ownership, this dam on TR-SNAKE CR river serves as a focal point for monitoring and ensuring safety measures are in place to address any potential hazards. As climate change impacts continue to influence water resource management, understanding the condition and risk profile of structures like Oknoname 111028 becomes crucial for sustainable planning and adaptation strategies.

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.
