About this dam

Wellsville Lake Dam

Wellsville Lake Dam in Montgomery, Missouri, is a state-owned structure completed in 1964 for the primary purpose of recreation. The dam, constructed with earth and buttress core types, has a height of 5 feet and a storage capacity of 240 acre-feet. Situated on TR-Little Loutre Creek, the dam serves as a recreational spot with a surface area of 16 acres and a drainage area of 115 square miles.

Despite being a low-risk structure, Wellsville Lake Dam has a high hazard potential, indicating the potential for significant consequences in case of failure. The dam has not been rated for its condition, with the last inspection conducted in August 1990. Emergency action plans (EAP) and risk management measures for the dam are not available, highlighting the need for updated safety protocols in the event of an emergency.

Located in Mineola, Missouri, Wellsville Lake Dam is overseen by the St. Louis District of the US Army Corps of Engineers. With a congressman representing the area, the dam continues to be a vital part of the region's water resource and climate conservation efforts. As enthusiasts in water resources and climate, staying informed about the condition and management of Wellsville Lake Dam is essential for understanding its role in the community and ensuring its safety and sustainability for future generations.

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 Wellsville Lake Dam

Where does the data for Wellsville Lake 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.
