Callahan Creek Watershed A-2 dam
Callahan Creek Watershed A-2
The Callahan Creek Watershed A-2 is a crucial infrastructure managed by the local government in Boone, Missouri, designed by the USDA NRCS. This earth dam, completed in 1975, serves the primary purpose of flood risk reduction for the area, with a height of 29 feet and a length of 620 feet. It has a storage capacity of 240 acre-feet and can handle a maximum discharge of 490 cubic feet per second.
Situated in the TR-CALLAHAN CREEK, this dam has a significant hazard potential and a moderate risk assessment. It is currently not rated for its condition assessment, with no inspection frequency specified. The spillway type is uncontrolled, with a width of 40 feet. Despite the lack of recent inspections and condition assessments, the Callahan Creek Watershed A-2 remains a critical structure for flood risk management in the region.
Water resource and climate enthusiasts will find interest in the Callahan Creek Watershed A-2 due to its vital role in flood risk reduction in the area. The dam's design and specifications, along with its strategic location in the watershed, make it an essential piece of infrastructure for managing water resources and mitigating potential risks associated with flooding events. With its construction dating back to 1975, this earth dam continues to play a crucial role in protecting the community and surrounding areas from the impacts of excessive water flow and potential disasters.

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 Callahan Creek Watershed A-2
Where does the data for Callahan Creek Watershed A-2 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.
