About this dam

Kelly Bros.

Kelly Bros. is a privately owned earth dam located in Nuyaka, Oklahoma, along the TR-Hopper Creek. Built in 1960, this dam stands at 30 feet in height and has a storage capacity of 50 acre-feet. With a spillway width of 1 foot and a controlled spillway type, Kelly Bros. is designed to manage maximum discharges of up to 480 cubic feet per second.

Managed by the Oklahoma Water Resources Board, Kelly Bros. is regularly inspected and maintained to ensure its structural integrity and safety. Despite its low hazard potential, the dam is classified as having a very high risk due to its critical importance in flood control and water resource management in the area. Emergency action plans are in place, though the dam's condition assessment remains unrated as of the last inspection in 2011.

Water resource and climate enthusiasts will appreciate the strategic location of Kelly Bros. in Creek County, Oklahoma, as it plays a crucial role in managing water flow and mitigating flood risks in the region. With its stone core and soil foundation, this dam is a key part of the infrastructure designed to protect residents and properties along TR-Hopper Creek. As a privately owned structure, Kelly Bros. exemplifies the importance of collaboration between private owners and state regulatory agencies in ensuring the safety and sustainability of water resources for future generations.

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 Kelly Bros.

Where does the data for Kelly Bros. 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.
