Hammett Lake Dam dam
Hammett Lake Dam
Hammett Lake Dam, located in Audrain County, Missouri, is a private earth dam constructed in 1978 for irrigation purposes along the TR-BEAR SLOUGH-CREEK. With a height of 24 feet and a length of 1747 feet, the dam has a storage capacity of 275 acre-feet, making it a vital resource for water management in the area. The dam's spillway is uncontrolled with a width of 20 feet, ensuring efficient water discharge during times of excess flow.
Despite being privately owned and not regulated by the state, Hammett Lake Dam poses a low hazard potential with a moderate risk assessment rating. The dam's condition is currently not rated, but its design and construction using stone core and soil foundation have contributed to its stability over the years. Emergency action plans and risk management measures are not documented, indicating a potential area for improvement in ensuring the safety and security of the dam and surrounding areas.
For water resource and climate enthusiasts, Hammett Lake Dam serves as a fascinating example of private infrastructure supporting agricultural activities in the region. Its strategic location and design highlight the importance of efficient water storage and management for irrigation purposes. As discussions around climate change and water scarcity continue to evolve, understanding the role of dams like Hammett Lake in ensuring sustainable water use and environmental resilience becomes increasingly crucial.

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 Hammett Lake Dam
Where does the data for Hammett 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.
