This is a paddling spot that few people know, partly because it is mostly invisible from roads and partly because it can only be paddled at high water.   Put your boat into the water at any of the river access points off Banks Road.   We went down from the end of Cooper Place, but there are several launch spots in this area.    Paddle across the river and enter the channel at the south end directly opposite Garnet Road (at N50 45.530 W120 20.324) paddling upstream for one mile in the back channel.   Watch for beavers, shore birds, and an eagles nest.   Emerge from the channel at a narrows and float downstream to your launch spot.
