About this dam

Oknoname 127010

Oknoname 127010, located in Pushmataha County, Oklahoma, is a privately owned earth dam completed in 1960 with a primary purpose of "Other." The dam stands at a height of 40 feet and has a hydraulic height of 37 feet, providing a maximum storage capacity of 528 acre-feet. Situated on the Briar Branch Creek, this structure serves various purposes and has a controlled spillway with a width of 2 feet. Despite its low hazard potential, the risk assessment for Oknoname 127010 indicates a very high risk level, highlighting the importance of effective risk management measures.

Owned and regulated by the Oklahoma Water Resources Board (OWRB), Oknoname 127010 has a history of state jurisdiction, permitting, inspection, and enforcement. The dam features a stone core and soil foundation, with a valve outlet gate for water control. The last inspection of this structure was conducted in October 2009, with a scheduled inspection frequency of 5 years. While the condition assessment is currently listed as "Not Rated," the risk assessment categorizes the dam as having a very high risk level, emphasizing the need for proactive risk management strategies to ensure its safety and integrity for the surrounding community and water resources.

With a surface area of 20 acres and a drainage area yet to be specified, Oknoname 127010 plays a crucial role in water storage and flood control in the region. The dam's location in Ethel, Oklahoma, under the jurisdiction of the Fort Worth District, highlights its significance in managing water resources in the area. As water resource and climate enthusiasts, understanding the design, purpose, and risk profile of dams like Oknoname 127010 is essential for promoting sustainable water management practices and ensuring the safety and resilience of critical infrastructure in the face of changing environmental conditions.

Dam data reference

Condition Assessment

Satisfactory
No 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.
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.
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.

Hazard Potential Classification

High
Dams 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, environmental 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.

FAQ

About Oknoname 127010

Where does the data for Oknoname 127010 come from?

Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.

How often is the report updated?

NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.

What does the Low hazard rating mean?

The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.

What's "% of normal"?

The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).

Can I get alerts when storage crosses a threshold?

Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
