The BDA treatments were designed to promote channel aggradation in order to reconnect incised stream reaches to adjacent floodplains. Long-term outcomes of the project included increased surface-groundwater connectivity, moderation of high summer temperatures, increased fish habitat quantity and quality, and increased productivity of steelhead populations.
BDA structures were composed of post lines driven across the channel and on to adjacent floodplain surfaces. Fill material relied on abundant local willow, cobbles, and gravels. During the project many of the BDA structures were enhance by natural beaver activity which increased the effectiveness of the treatments in the process of incision recovery.
