Dakota and Goodhue counties and the City of Cannon Falls finalized an emergency evacuation plan.
The dam has been safely operated for more than a century. We maintain a well-rehearsed emergency plan in the unlikely event of a structural failure. This could cause rapid flooding downstream.
That plan includes the following direction for people in the Cannon Falls area:
- Listen: Listen for the special siren indicating a failure at the dam
- Get out: Leave your home immediately with only people and pets
- Gather: Meet at your designated assembly location
There are just minutes to evacuate, so only take people and pets with you. Once at the collection point, move to allow others to safely arrive. Law enforcement and first responders will collect your information and provide instructions. See interactive map.

Flood warning system
The siren warning system within Cannon Falls is improved. Sirens will warn residents within the city limits of a possible high-water event. This is required by the Federal Energy Regulatory Commission.
Four sirens are strategically located downstream of the dam in Cannon Falls. 
Listen to the siren. Listen to the emergency message.
