Asarco Lake Dam dam
Asarco Lake Dam
Asarco Lake Dam, located in Glover, Missouri, is a private dam built in 1971 primarily for recreational purposes and water supply. The dam, standing at a height of 50 feet with a structural height of 51 feet, spans 700 feet and has a storage capacity of 2056 acre-feet. It serves as a vital water resource for the area, with a drainage area of 477 square miles and a maximum discharge rate of 1080 cubic feet per second.
Managed by the Dam and Reservoir Safety Program in Missouri, Asarco Lake Dam has a high hazard potential and is inspected every 3 years, with the last assessment conducted in February 2018. Despite its satisfactory condition as of December 2007, the dam's risk assessment is classified as moderate. The spillway, with a width of 50 feet, is uncontrolled and equipped with a valve outlet gate. In case of emergencies, an Emergency Action Plan (EAP) is in place, last revised in February 2015.
With its scenic 34-acre surface area and recreational amenities, Asarco Lake Dam provides a picturesque backdrop for outdoor activities while playing a crucial role in water supply management. Enthusiasts of water resources and climate will be drawn to the blend of natural beauty and infrastructure that this dam offers in Iron County, Missouri.

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.
Plan around the weather

About Asarco Lake Dam
Where does the data for Asarco 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.
