Hammond Lake Dam dam
Hammond Lake Dam
Hammond Lake Dam, located in Clarksburg, Missouri, is a privately owned Earth dam that was completed in 1985 by designer Gene Brown. The dam stands at a height of 48 feet and has a length of 520 feet, with a maximum storage capacity of 816 acre-feet. It serves as a vital structure for regulating the flow of water in the tributary to Draffen Branch, covering a surface area of 9 acres and draining a watershed of 34 square miles.
Managed by the Dam and Reservoir Safety Program in Missouri, Hammond Lake Dam is regularly inspected and regulated to ensure its safety and reliability. Despite being categorized as having a low hazard potential, the dam is considered to have a moderate risk level due to certain factors. With no outlet gates and an uncontrolled spillway type, the dam presents unique challenges in managing water discharge during peak flow periods. While the condition assessment is currently not rated, ongoing risk management measures are in place to address potential hazards and maintain the dam's integrity for the future.
For water resource and climate enthusiasts, Hammond Lake Dam offers a fascinating example of Earth dam construction and management within the Kansas City District. Its role in controlling water flow and providing storage capacity in Cooper County showcases the importance of effective dam infrastructure for maintaining water resources in the region. As a privately owned structure, the dam's compliance with state regulations and safety protocols highlights the collaborative efforts between owners, designers, and regulatory agencies to ensure the longevity and functionality of vital water infrastructure in Missouri.

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 Hammond Lake Dam
Where does the data for Hammond 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 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.
