Dresser Minerals #7 Dam South (Dry) dam
Dresser Minerals #7 Dam South (Dry)
Dresser Minerals #7 Dam South (Dry) in Washington, Missouri, is a privately owned structure built in 1950 primarily for tailings storage. This rockfill dam stands at a height of 34.6 feet and spans a length of 4000 feet along TR-Mill Creek. With a storage capacity of 80 acre-feet, this dam has a surface area of 37 acres and serves a critical role in managing water resources in the region.
Despite its importance, Dresser Minerals #7 Dam South (Dry) has not been subject to state regulation or inspection since its last assessment in 1986. The dam is classified as having a high hazard potential and a moderate risk assessment, indicating the need for continued monitoring and maintenance to ensure its structural integrity. The lack of a current condition assessment raises concerns about the dam's resilience to extreme weather events, especially in the face of changing climate patterns.
As water resource and climate enthusiasts, it is crucial to recognize the significance of Dresser Minerals #7 Dam South (Dry) in the local ecosystem and the potential risks associated with its aging infrastructure. Advocating for increased regulatory oversight, regular inspections, and proactive risk management measures will be essential to safeguarding this dam and protecting the surrounding community from potential hazards in the future.

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 Dresser Minerals #7 Dam South (Dry)
Where does the data for Dresser Minerals #7 Dam South (Dry) 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.
