Flooding Preparedness

How You Can be Prepared

Flooding poses a threat to life and safety and can cause severe damage to public and private property. Below are some links you may find helpful when preparing for flooding. 

Flood Smart

River levels in Clackamas County are monitored by a network of river gauges that help us predict the when peak water levels will occur in our communities. We also work with fire districts to provide sand bag distribution locations to assist residents in protecting their homes from flooding.
