Mcminn Lake #1 Dam dam
Mcminn Lake #1 Dam
Mcminn Lake #1 Dam, located in Bollinger, Missouri, is a privately owned structure designed by HEAGLER and completed in 2013. This Earth type dam stands at a height of 43.5 feet with a hydraulic height matching that measurement. It serves as a critical infrastructure on the TRIB LITTLE WHITE stream, providing a maximum storage capacity of 443 acre-feet and a normal storage level of 382 acre-feet.
With a drainage area of 456 square miles, Mcminn Lake #1 Dam plays a key role in managing water resources in the region, with a high hazard potential but currently assessed as satisfactory in condition. The dam features uncontrolled outlet gates and a spillway width of 9 feet. Regular inspections are conducted to ensure its safety and compliance with state regulations, as the DAM AND RESERVOIR SAFETY PROGRAM oversees its permitting, inspection, and enforcement processes.
Despite its relatively recent construction, Mcminn Lake #1 Dam has already proven its importance in flood control and water supply management. The dam's strategic location, design, and operational features make it a vital component in the water resource infrastructure of Missouri, demonstrating the crucial role that such structures play in safeguarding communities against water-related risks and enhancing overall climate resilience in the region.

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 Mcminn Lake #1 Dam
Where does the data for Mcminn Lake #1 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 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.
