Summary
Constructed in 1940, this Earth-type dam stands at a height of 25 feet and has a length of 400 feet. It has a storage capacity of 300 acre-feet and serves a primary purpose classified as 'Other'. The dam is regulated by the Oklahoma Water Resources Board (OWRB) and is subject to state permitting, inspection, and enforcement.
Situated on the TR-Sycamore Creek, Oknoname 031047 has a controlled spillway with a width of 1 foot and a maximum discharge capacity of 700 cubic feet per second. Despite its low hazard potential, the dam is rated as having a very high risk due to its condition assessment being 'Not Rated'. The inspection frequency for this dam is every 5 years, with the last inspection conducted in November 2001. While emergency action plans and risk management measures are not specified, the dam is not owned or funded by any federal agency.
Water resource and climate enthusiasts interested in the infrastructure of dams will find Oknoname 031047 to be a fascinating case study. With its unique design features, location, and regulatory oversight, this dam presents an intriguing blend of historical significance and contemporary management challenges. The detailed data provided offers valuable insights into the characteristics and risk profile of this particular water resource structure, making it a noteworthy subject for further exploration and analysis in the context of sustainable 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.
