Clarence Cannon Mem Watershed Dam 11 dam
Clarence Cannon Mem Watershed Dam 11
Clarence Cannon Memorial Watershed Dam 11, located in Lincoln County, Missouri, is a vital structure managed by the local government to reduce flood risks in the area. Constructed in 1974 by the USDA NRCS, this earth dam stands at a height of 33 feet and spans a length of 685 feet, with a capacity to store up to 128 acre-feet of water from the TR-Bryants Creek. Despite its low hazard potential, the dam's purpose primarily focuses on flood risk reduction, reflecting its critical role in protecting the surrounding community from potential water-related disasters.
With a drainage area of 147.2 square miles and a maximum discharge capacity of 470 cubic feet per second, Clarence Cannon Dam 11 plays a crucial role in managing water flow in the region. The dam's uncontrolled spillway, 40 feet wide, ensures safe water release during times of excess inflow. Although the dam's condition is currently not rated, its moderate risk assessment underscores the importance of ongoing monitoring and maintenance to ensure its continued effectiveness in flood mitigation. Water resource and climate enthusiasts can appreciate the significance of this structure in safeguarding the local community and environment from the impacts of extreme weather events.
Dam data reference
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.
Plan around the weather
Same NOAA / yr.no feed Snoflo's iOS app uses. Watch the precipitation column on the meteogram -- rain on the basin upstream typically lifts inflow 24-72 hours later.

About Clarence Cannon Mem Watershed Dam 11
Where does the data for Clarence Cannon Mem Watershed Dam 11 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.
