The walleye's are never hitting on Colby, best bet is cross the highway to Whitewater. I grew up across the street from Colby, and it's a good northern/panfish lake. Eye's are few and far between though. Grouse used to be pretty good south of town on highway 11 and the Mooseline road, but haven't been up there this year yet.
If it ain't broke, your not trying hard enough!!
