The run is on in the Rock River. The water has crested the critical 42 degree temperature, and fish are moving in groups. The mouth has been the most consistent, but anglers in Jefferson and Fort are starting to see schools of fish.
Live bait, especially larger sized fatheads on a jig with stinger hook are catching the most fish. The typical rock-river patterns working especially well, orange or gold head with a chartruese body and/or live bait. Anchoring and fishing with three way-rigs or kytock setups works pretty well.
Look for slack water areas adjacent to the main current, that's where the lion's share of the fish are being caught.
It's only going to get better.
