John R dam
John R
John R is a privately owned dam located in Cleveland, Oklahoma, specifically in the city of CORBETT. Completed in 1969, this earth dam stands at a height of 18 feet and has a length of 1400 feet. It serves the primary purpose of "Other" and has a storage capacity of 130 acre-feet, with a normal storage level of 60 acre-feet. The dam is regulated by the Oklahoma Water Resources Board and undergoes regular inspections, with the last one conducted in August 2010.
Situated on the TR-BUCKHEAD CR river/stream within the Tulsa District, John R features a controlled spillway and one valve outlet gate. Despite its low hazard potential, the dam is categorized as having a very high risk due to its condition assessment being marked as "Not Rated." The dam poses a maximum discharge of 1719 cubic feet per second in the event of an emergency. While it has not been modified in recent years, the dam's risk management measures and emergency action plans are presently not up to date, raising concerns for potential risks in the future.
Overall, John R represents a significant water resource structure in Oklahoma with its historical significance and key role in water management. As a privately owned dam, its condition and risk assessment require attention to ensure the safety of surrounding communities and the preservation of the environment. Climate and water resource enthusiasts may find interest in further exploring the regulatory framework and potential mitigation measures for this important infrastructure.

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.

About John R
Where does the data for John R 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.
