About this dam

Oknoname 111076

Oknoname 111076 is a privately owned dam located in Okmulgee, Oklahoma, with a primary purpose classified as "Other". Constructed in 1960, this Earth dam stands at a height of 30 feet and spans a length of 3630 feet along the TR-GRAVE CREEK river or stream. With a storage capacity of 450 acre-feet and a surface area of 6 acres, this dam plays a crucial role in managing water resources in the region.

Managed by the Oklahoma Water Resources Board (OWRB), Oknoname 111076 has been deemed to have a low hazard potential, but a very high risk assessment rating. Despite being in operation for several decades, the dam's condition assessment remains unrated, with the last inspection conducted in August 2011. With state-regulated enforcement, inspection, and permitting in place, this dam serves as a vital infrastructure for water resource management in the area, with a controlled spillway and valve outlet gates ensuring efficient water flow and storage.

For water resource and climate enthusiasts, Oknoname 111076 presents an intriguing case study of a privately owned dam in Oklahoma. With its unique design features and historical significance, this Earth dam stands as a testament to the importance of infrastructure in managing water resources and mitigating risks associated with potential hazards. As efforts continue to ensure the safety and efficiency of this dam, its role in shaping the local water ecosystem remains paramount, highlighting the intersection of human ingenuity and environmental stewardship in the face of changing climate patterns.

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 111076

Where does the data for Oknoname 111076 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.
