Lone Elk Lower Dam dam
Lone Elk Lower Dam
Lone Elk Lower Dam, located in St. Louis, Missouri, serves multiple purposes including fire protection, stock, and small fish pond management. This earth dam, completed in 1966, stands at a height of 45 feet and stretches 600 feet in length. With a storage capacity of 331 acre-feet and a surface area of 39 acres, the dam plays a crucial role in managing water resources in the area.
The dam is primarily regulated by the DAM AND RESERVOIR SAFETY PROG in Missouri and undergoes regular inspections to ensure its structural integrity. Despite being classified as having a low hazard potential, the dam's risk assessment is rated as high (2). However, its condition has been assessed as satisfactory, with the last inspection conducted in January 2018. The surrounding area, including the TR TO MERAMEC RIVER, benefits from the recreational opportunities provided by the dam.
Lone Elk Lower Dam is a vital infrastructure for the Peerless Park community, contributing to water management, fire protection, and recreational activities. Its strategic location and design ensure the efficient utilization of water resources while maintaining safety standards. As climate enthusiasts, understanding the role of dams like Lone Elk Lower Dam in local ecosystems is crucial for promoting sustainable water resource management practices and 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 Lone Elk Lower Dam
Where does the data for Lone Elk Lower 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 Low 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.
