About this dam

Scarbow Lake

Scarbow Lake, located in Mayes County, Oklahoma, is a man-made reservoir primarily owned and regulated by the local government for recreational purposes. The dam, completed in 1960, is an earth structure with a height of 17 feet and a hydraulic height of 12 feet. The lake has a storage capacity of 200 acre-feet, with a maximum discharge capacity of 2460 cubic feet per second. The spillway is controlled with a width of 1 foot, and the hazard potential is rated as low.

Despite its low hazard potential, Scarbow Lake is considered to have a very high risk due to its location near the TR-PRYOR CR river and the surrounding area. The dam is regularly inspected every five years, with the last inspection taking place in December 2010. The lake is equipped with a valve outlet gate and has not been rated for its condition assessment. While the risk assessment is high, there are currently no specific risk management measures in place for the reservoir.

Overall, Scarbow Lake offers a picturesque spot for recreational activities in Pryor, Oklahoma, attracting water resource and climate enthusiasts alike. With its tranquil waters and scenic surroundings, the lake provides a perfect setting for fishing, boating, and other outdoor activities. However, the high risk rating underscores the importance of continued monitoring and management to ensure the safety and longevity of this popular water resource.

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 Scarbow Lake

Where does the data for Scarbow Lake 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.
