Where is Abernethy Watershed?
Abernethy Creek flows through both rural and incorporated Clackamas County. It enters the Willamette in Oregon City. During the 1996 floods, Abernethy Creek overflowed its banks and submerged low lying lands in Oregon City including Clackamas County office buildings.

Why conserve this land?
Abernethy Creek is home to steelhead and other fish. Its steep ravines are still forested, providing shade and woody debris for healthy fish populations.
Our Accomplishments
Three Rivers Land Conservancy (now Columbia Land Trust) holds two conservation easement properties in Abernethy Creek.
The first is the Pizzo property and the second is the Rambo property. Each property contains a portion of Abernethy Creek.
