Lake Alexander Dam dam
Lake Alexander Dam
Lake Alexander Dam, located in Putnam, Missouri, is a privately-owned structure primarily used for irrigation purposes. Completed in 2004, this earth-type dam stands at a height of 42 feet, with a hydraulic height of 37 feet. It has a storage capacity of 2172 acre-feet and covers a surface area of 102 acres. The dam regulates water flow from the tributary Barber Creek, serving the surrounding area for irrigation and recreational activities.
Managed by the DAM AND RESERVOIR SAFETY PROG, the Lake Alexander Dam is subject to state regulations, inspections, and enforcement to ensure its safety and functionality. Despite being classified as having a significant hazard potential, the dam's condition assessment in 2008 deemed it satisfactory. The risk assessment for the structure is moderate, indicating a level 3 risk. With a last inspection date in March 2018 and an inspection frequency of 5 years, efforts are in place to monitor and maintain the dam's integrity.
While the dam has not experienced any major modifications or incidents, it is crucial for water resource and climate enthusiasts to stay informed about its risk management measures and emergency preparedness. With its vital role in irrigation and recreation, Lake Alexander Dam serves as a significant resource in the region, highlighting the importance of ongoing monitoring and maintenance to ensure its continued functionality and safety.

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 Alexander Dam
Where does the data for Lake Alexander 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 Significant 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.
