Be careful and watch out for motor boats. We just had a death in this area from a kayak / motorboat collision. Husband and wife were kayaking on a lake in the Adirondacks and were capsized by a passing boat. Authorities still aren't sure if it actually struck them. Wife was saved by witnesses on beach but husband drowned. Both had life vests but were not wearing them.
PS I love that area by the Russian River. Very beautiful. If you canoe where no motorboats can go, even better!
