When the temperatures hit 100 there is only one thing to do, pick a spot to drop into the river.
Leavenworth does not disappoint.
Lake Wenatchee, also a good choice.
Drop into the Wenatchee river at the bridge in Plain and pop out at Ponderosa. Or Jump in at Mosquito flats, between mile marker 16 and 17 on the Beaver valley road for a longer float and jump out at the bridge.
