I have both of the books you guys are talking about plus
one called "Washington's Best Lake Fly Fishing",by Nathan Caproni
which is usefull too. I use all three on occasion.
But one less known book I have is the one I use the most.
It's called "Lakes of Washington" volume II, Eastern Washington.
Second Edition. It's published by the Dept of Ecology and was obtainable
from them.
I don't know if it's been updated, but suspect so. Also I'm sure there is
a Volume I for Western Washington.
It lists every lake and beaver pond and puddle of any size in the
entire region by legal description.It has information on size and
depth of many of the more significant waters. Also lists info. on water
chemistry of our alkaline lakes as well as fish species for some lakes
and waterfoul useage value of some of the shallower ones.
It's a great book for the fisherman,duckhunter to own.
