Sambo - Get a Wa.St. Road Map and follow hiway 17 due North from Pasco to Othello. Mesa Lk., Scooteny Res., and of course the Potholes Res.. Lived there for 8 yrs. and took the kids on regular outings with good results. Beyond Sprague Lk. are several great trout waters in Williams, Badger and Downs. This 61 YO used fish them with the Gandparents in the 40's.
