I have started using Shad raps more with a good amount of success. Grind the bottom in deeper holes and around structure and hang on!

Rock River—July 3–The fishing was tough. I grinded for a half-day just for this one largemouth one a spinnerbait. Spinnerbaits seem to be the ticket for dirty rivers.

Rock River—June 19–The River finally warmed up enough for the bass to get shallow. We caught a mixed bag including a handful of bass on soft paddle-tail swimbaits on a jighead.

May 30–With the water still being somewhat cold, I tied on a spinnerbait and slow-rolled it around lay downs. We didn’t get many hits, but this one was almost 4 lbs so it paid off.

Rock River—October 17/24–My dad and I went out for some fall walleye and ended up catching 8-10 nice walleye on jig-and-plastic presentations. We had to fish pretty slow since it was close to freezing temps outside, but it was worth it. We focused on deep holes and channels. I then hit a local pond and used a Megabass Vision 110 to catch a half dozen largemouth on shoreline drop offs.

Rock River—September 6–This was by far the best bass fishing weekend of the year on the River. Between crank baits, spinnerbaits, and soft swimbaits, I caught about a dozen largemouth and smallmouth up in shallow rocks and wood. This solid largemouth came on a Swimbait. Also caught a bonus channel cat on the swimbait!

Rock River—August 7–The River was as warm as a bathtub, which made fishing tough. We caught some other random species, and then I caught this big smallie (about 3 lbs) on a black and purple chatterbait in the grass. I was fishing it pretty slow.
