New Melle Quarry Dam dam
New Melle Quarry Dam
The New Melle Quarry Dam, located in St. Charles, Missouri, is a private dam that serves as a crucial water resource for the surrounding area. Completed in 1999, this earth dam stands at a height of 90 feet and has a storage capacity of 380 acre-feet. With a drainage area of 63 square miles and a maximum discharge rate of 2787 cubic feet per second, the dam plays a vital role in managing water flow and ensuring water security for the community.
Managed by the DAM AND RESERVOIR SAFETY PROG in Missouri, the New Melle Quarry Dam is subject to regular inspections, with its condition assessed as satisfactory during the most recent inspection in 2007. Despite being classified as having a high hazard potential, the dam has a history of meeting safety guidelines and maintaining a satisfactory condition. With a spillway width of 0 feet and no associated locks, the dam primarily serves the purpose of water storage and flood control, contributing to the overall water management infrastructure in the region.
Overall, the New Melle Quarry Dam stands as a significant engineering feat, providing essential water storage and flood control capabilities for the community. As a private structure regulated by the state, the dam's design and construction demonstrate a commitment to water resource management and ensuring the safety of the surrounding area. With a focus on sustainability and efficient water utilization, the dam plays a crucial role in mitigating the impact of climate change on water resources 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 New Melle Quarry Dam
Where does the data for New Melle Quarry 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.
