Summary
Built in 1950, the dam stands at 20 feet tall and spans 510 feet in length, with a storage capacity of 82 acre-feet. It is regulated by the Oklahoma Water Resources Board (OWRB) and is subject to state permitting, inspection, and enforcement.
The primary purpose of Oknoname 087030 is categorized as 'Other', with a low hazard potential and a very high risk assessment rating. The dam features a controlled spillway and one outlet gate. While its condition assessment is listed as 'Not Rated', it undergoes inspection every five years, with the last inspection conducted in July 2005. The dam's risk management measures, emergency action plan, and inundation maps status are not specified in the provided data.
Located along the TR-Finn Creek, this dam represents a significant water resource structure in the region, contributing to flood control and water storage. Enthusiasts and experts in water resource management and climate change will find Oknoname 087030 to be an intriguing case study, showcasing the importance of proper regulation, maintenance, and risk assessment for dams in ensuring public safety and efficient water management practices.

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.
