Mccannon Lake Dam dam
Mccannon Lake Dam
Mccannon Lake Dam, located in Holden, Missouri, is a privately owned structure primarily used for irrigation purposes. The dam, classified as an Earth type with a height of 25 feet, provides a storage capacity of 160 acre-feet and covers a surface area of 12 acres. With a drainage area of 410 square miles, the dam plays a crucial role in water supply management in the region.
Despite being privately owned, Mccannon Lake Dam has a high hazard potential, but its condition assessment is marked as "Not Rated." The dam's emergency action plan status, risk assessment, and management measures are currently unspecified, highlighting areas of potential improvement for its safety and resilience. With its location on the TR-WEST PIN OAK CREEK, the dam's impact on the local ecosystem and water resources underscores the importance of regular inspections and maintenance to ensure public safety and environmental protection.
As an integral part of the water infrastructure in Johnson County, Missouri, Mccannon Lake Dam warrants attention from water resource and climate enthusiasts. Its role in irrigation and water supply, combined with its high hazard potential, calls for proactive measures to enhance its safety and resilience. Monitoring its condition, emergency preparedness, and risk management strategies are crucial steps towards safeguarding the dam and the surrounding community from potential risks and ensuring sustainable water resource management in the region.

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 Mccannon Lake Dam
Where does the data for Mccannon 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 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.
