What's your point SQ?

The flooding that occurred in the Skagit and other north and central Puget Sound basins were, for lack of a better word, doozies--very near 100 yr events. Man-made logjams can withstand 1-3 yr flood events often better than their natural counterparts because they're anchored in various ways to the bank. But not much sitting in the main channel of these rivers stands much of a chance with the type of floods we saw over the past couple of weeks.

The important thing is that they're displaced downstream like any other wood, coming to rest again where they can again do some good. Given the level of diking that has occurred on our lower rivers, substantially reducing off-channel habitats and sloughs important to juvenile salmon, LWD can serve an accentuated role displaced from upstream habitats into lower rivers. Even if they're shoved out of the river into the estuary or nearshore marine areas, there is evidence that they provide important habitat functions in tidal channels and marine beaches. And hopefully, they're replaced with other debris originating from areas upstream.
