About this dam

Oknoname 30073

Oknoname 30073, located in Harper, Oklahoma, is a privately owned dam designed by USDA NRCS and regulated by the Oklahoma Water Resources Board. Completed in 2000, this earth dam stands at a height of 26.5 feet and has a storage capacity of 95 acre-feet. Situated on an unnamed tributary of Buffalo Creek, this structure serves multiple purposes and has a low hazard potential.

Despite being categorized as low risk, Oknoname 30073 has a very high risk assessment score of 1. With a controlled spillway and a single valve outlet gate, this dam has not been rated for its condition assessment. The last inspection date was in August 2011, with an inspection frequency of 5 years. While emergency action plans and inundation maps are not prepared, the dam meets regulatory guidelines and is monitored for enforcement, inspection, and permitting by the state agency.

Overall, Oknoname 30073 is a crucial water resource structure in Oklahoma, providing storage for 50 acre-feet of water and covering a surface area of 6.8 acres. Despite its low hazard potential, the dam's risk assessment highlights the need for continued monitoring and management to ensure the safety and effectiveness of this essential infrastructure in the face of climate challenges.

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 30073

Where does the data for Oknoname 30073 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.
