Pheasant Run Lake Dam dam
Pheasant Run Lake Dam
Pheasant Run Lake Dam, located in St. Charles, Missouri, was completed in 1972 for the primary purpose of recreation. This earth dam with a structural height of 30 feet holds a normal storage capacity of 36 acre-feet and has a maximum storage of 64 acre-feet. The dam sits on Louisville Creek and covers a surface area of 4 acres with a drainage area of 150 square miles.
Despite its recreational purpose, Pheasant Run Lake Dam has a high hazard potential, although its condition assessment is currently marked as "Not Rated." The dam has not been inspected recently, and there is no established inspection frequency. The dam's emergency action plan status and risk assessment information are also not available. With its ownership under a private entity and no state jurisdiction or regulation, the responsibility for the dam's maintenance and safety lies solely on the private owner.
Water resource and climate enthusiasts interested in Pheasant Run Lake Dam will find its unique design as an earth dam with a buttress core type intriguing. The dam's location on Louisville Creek and its proximity to the Kansas City District USACE office add to its significance. While offering recreational opportunities, the dam's lack of recent inspection and unclear emergency preparedness raise concerns about its safety and the potential risks it poses to the surrounding area in case of a dam failure.

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 Pheasant Run Lake Dam
Where does the data for Pheasant Run 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.
