Isolated Side Channels and Off-Channel Habitats
The Lower Clackamas River watershed encompasses 15,428 acres of mostly industrial, urban, and residential development. The project would reconnect a historic side channel, add large wood structures, improve native plant densities and manage invasive species. There are existing barbs, and dikes on this property that would need to be modified or removed. There are two side channels that would be reconnected. The first is 2700 feet and the second is 1700 feet totaling 4400 feet of off channel habitat that would be created. This stretch of the Lower Clackamas would have been highly complex with multiple channels but over the years the river has been confined to a single channel.
