Summary
Constructed in 1960, this earth dam stands at 20 feet tall and spans 390 feet in length, with a storage capacity of 110 acre-feet. The dam serves a primary purpose of "Other" and is regulated by the Oklahoma Water Resources Board (OWRB), with state jurisdiction, permitting, inspection, and enforcement in place.
Despite its low hazard potential, Oknoname 049001 is classified as having a very high risk due to unspecified factors. The dam features a controlled spillway and a single valve outlet gate. While the condition assessment is listed as "Not Rated," the last inspection took place in April 2010, with a scheduled inspection frequency of every five years. The dam is situated within the Tulsa District of the US Army Corps of Engineers but is not owned or funded by any federal agency.
Water resource and climate enthusiasts will find Oknoname 049001 an intriguing subject for further study, given its unique design and location in Garvin County, Oklahoma. With its stone core and soil foundation, this dam represents an important piece of infrastructure within the state, contributing to water storage and management along the TR-Cheek Creek. As efforts to address climate change and water scarcity continue, understanding the condition and risk profile of dams like Oknoname 049001 is crucial for ensuring the safety and sustainability of our water resources.

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.
