 The reason that we're here doing river restoration is because for 30, 40, 50, 60 years, they've been clearing out the large wood out of the stream for various reasons. When you remove these roughness elements, the river responds by getting further removed from the floodplain. And what we really want is the water out on the floodplain. That gives us the habitat complexity and diversity that juvenile salmon sealhead need. To immediately see that biological response is tremendously rewarding.
