The Beebe Side Channel project (RM 4.5) will increase available off-channel habitat by reconnecting and enhancing a remnant side-channel in the lower Clackamas River downstream of Carver. The project will enhance connectivity between the river and the side channel, allowing for longer duration rearing by juvenile salmonids in a complex side channel as opposed to the mainstem river. The lower 2/3 of the side channel lacks complex and varied habitat and is very wide (100-200) and shallow (most less than 2), leading to warm water temperatures in the. It also lacks the overhead cover and complex habitat created by large wood that would be expected in a PNW stream. The project will excavate at the upper end of the side channel to increase the amount and duration of flow connection from the early fall through late spring. One existing perched alcove will be deepened with large wood added and another alcove excavated in the island for additional habitat benefits. The material excavated from the side channel entrance, alcoves and new pools will be used to build up two river bars in the existing channel to narrow the currently wide and shallow stream channel. Large wood will be incorporated into the gravel bars along with extensive willow staking. The project involves riparian planting with native vegetation and invasive plant removal along the Clackamas River. Project partners include the, Clackamas County, Clackamas WES, Oregon Dept. of Fish & Wildlife, Johnson Creek Watershed Council, and the Clackamas Partnership.
