Lake Chesterfield Dam dam
Lake Chesterfield Dam
Lake Chesterfield Dam, located in Chesterfield, Missouri, is a private earth dam primarily used for recreation purposes. With a height of 30 feet and a storage capacity of 433 acre-feet, the dam impounds water from the TR Chaulks Creek, creating a surface area of 27 acres for recreational activities. Despite its high hazard potential, the dam's condition has not been rated, highlighting the need for regular inspections and maintenance to ensure its safety.
The dam, constructed with a buttress core type on an unlisted/unknown foundation, is not regulated or inspected by the state, making it crucial for the private owners to take responsibility for its upkeep. The dam's proximity to the Kansas City District and its association with the US Army Corps of Engineers adds a layer of complexity to its management and potential risks. With no emergency action plan in place and limited information on its risk assessment, stakeholders and enthusiasts alike should advocate for improved safety measures and regular monitoring to prevent any potential disasters.
As a significant recreational asset in the area, Lake Chesterfield Dam serves as a popular destination for water resource and climate enthusiasts. While its high hazard potential and lack of state regulation raise concerns, the dam's scenic beauty and recreational opportunities make it a valuable resource for the community. By prioritizing safety measures, conducting regular inspections, and investing in maintenance, the dam can continue to provide enjoyment for visitors while minimizing risks associated with its operation.

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 Lake Chesterfield Dam
Where does the data for Lake Chesterfield 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.
