Where I90 crosses Moses Lake is supposed to be killer for crappies in the spring, the Coulee City marina should be producing perch right about now, I would assume through the ice, if you have a boat Billy Clapp is a under utilized lake with lots of everything. If you really want to catch a lot of perch hit the Winchester Wasteway from Jan. to about March, where it crosses road 5 about 5miles east of Quincy, you can catch perch all day there.
