Manual Oakley Group Dam dam
Manual Oakley Group Dam
The Manual Oakley Group Dam, located in Teton, Montana, is a privately owned earth dam constructed in 1963 by the USDA NRCS for recreational purposes on TR-Muddy Creek. With a height of 20 feet and a length of 335 feet, the dam provides a storage capacity of 41 acre-feet and a maximum discharge of 27 cubic feet per second. Despite being uncontrolled, the spillway width is 18 feet, ensuring the safety of the dam during high-water events.
The significant hazard potential of the Manual Oakley Group Dam, combined with its moderate risk assessment rating, highlights the importance of regular inspections and maintenance to ensure its structural integrity. While the dam's condition assessment is currently listed as "Not Rated," the state regulatory agency (DNRC) mandates regular inspections, permitting, and enforcement to mitigate any potential risks. With a designated emergency action plan (EAP) pending evaluation, it's crucial for stakeholders and water resource enthusiasts to stay informed about the dam's risk management measures and emergency procedures.
As a key recreational feature in the area, the Manual Oakley Group Dam serves as a vital water resource for the community. With its strategic location and historical significance in the region, the dam's preservation and maintenance are essential for ensuring safe and sustainable water management practices. Climate and water resource enthusiasts can appreciate the dam's role in providing recreational opportunities while also acknowledging the importance of ongoing monitoring and risk assessment to safeguard its long-term viability.
Dam data reference
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 Manual Oakley Group Dam
Where does the data for Manual Oakley Group Dam 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 Significant 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.
