About this dam

Stone Canyon

Stone Canyon is a private recreational dam located in Owasso, Oklahoma, along an unnamed tributary to Elm Creek. Built in 2009, this earth dam stands at a height of 32 feet and stretches 5280 feet in length, creating a reservoir with a storage capacity of 2110 acre-feet. The dam is primarily used for recreation purposes, offering activities such as boating and fishing in its 104-acre surface area. Despite its fair condition assessment, Stone Canyon poses a high hazard potential, prompting regular inspections and maintenance to ensure its safety.

Managed by the Oklahoma Water Resources Board, Stone Canyon is equipped with a controlled spillway and a single valve outlet gate. The dam is located in Rogers County and falls under the jurisdiction of the state regulatory agency, with inspection, permitting, and enforcement processes in place. With a risk assessment rating of "Very High (1)", the dam's emergency action plan is crucial in mitigating potential hazards and ensuring public safety in the event of a breach or emergency. Overall, Stone Canyon serves as a popular recreational destination while also highlighting the importance of proper water resource management and climate resilience strategies in the face of increasing risks posed by climate change.

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 Stone Canyon

Where does the data for Stone Canyon 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 High 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.
