Degraded Channel and Riparian Areas
Isolated Side Channels and Off-Channel Habitats
Realignment of Foster Creek would result in 1,450 linear feet of side channel habitat increase. Roughened channel construction is anticipated to encourage occupation of the former channel alignment, support salmonid access, and protect upstream infrastructure.
1,200 linear feet of large wood placement is proposed. Placement includes six habitat complexity log jams, (eight to twelve pieces each), distributed throughout the re-occupied Foster Creek channel. These
structures are intended to provide cover and complexity and would be placed to avoid impact to existing mature vegetation. Five buried channel margin jams will redirect flow down the former alignment.
