Damage Done by Recent Floods
Flooding events during the last 50 years have ravaged parts of Clackamas County. Just some of the results of these events include:
- In the 1964 flood in Clackamas County, one man died when his house collapsed into Wildcat Creek.
- In the 1964 flood, almost forty homes near the Brightwood area alone were completely destroyed with no trace of having been there.
- In the 1964 flood, the Oregon City Shopping Center was inundated by 34.5 inches of water, with the shopping basements of JCPenney and Grants being completely submerged.
- In the 2011 flood, nearly $4 million was needed for repairs to public infrastructure that included damages to Lolo Pass Road, the Zigzag River bridge, and county Water Environment Services wastewater facilities.
- In the 2011 flood, at least 37 residential properties suffered significant bank erosion and face increased future erosion threats.

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. The County also works with fire districts to provide sand bag distribution locations to assist residents in protecting their homes from flooding. There are several local area commercial sandbag providers.
