Bryant No 6 dam
Bryant No 6
Bryant No 6 is a privately-owned earth dam situated in Dewey, Oklahoma, along the TR TEPEE CR river. Built in 1975 by the USDA NRCS, this dam stands at a height of 25 feet and has a storage capacity of 60 acre-feet. With a controlled spillway type and a maximum discharge of 810 cubic feet per second, Bryant No 6 serves a primary purpose of "Other" and is regulated by the OWRB.
Despite being rated as a low hazard potential structure with a very high risk assessment, Bryant No 6 has not been inspected since 2005, with a scheduled inspection frequency of 5 years. The dam features a single valve outlet gate and is constructed of stone core types with soil foundations. While the condition assessment is currently listed as "Not Rated," the risk management measures and emergency response preparedness for this dam are not explicitly documented.
Water resource and climate enthusiasts will find Bryant No 6 to be an intriguing case study in dam infrastructure maintenance and risk assessment. With its unique design and geographical location, this dam presents an opportunity for further exploration into the regulatory oversight and management of private dams in Oklahoma. As efforts are made to address the high risk associated with this structure, stakeholders and policymakers may look towards enhancing inspection protocols and emergency response preparedness to ensure the safety and security of Bryant No 6 and surrounding communities.

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 Bryant No 6
Where does the data for Bryant No 6 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.
