Make A Map

By request, I tracked down the marked map for Lake Koshkonong. It was marked by Tom Rawski and appeared in a 1965 issue of Fishing News. The writeup stated, “This guy catches fish. And he is one of the very few who will take the time to write up his secrets.”

Here is an edited version of some of his comments on fishing the lake:

✅ Lake Koshkonong offers exceptionally good fishing for northerns, crappies, walleyes, perch, and catfish. But Koshkonong is generally accepted as one of the finest lakes for white bass in the state of Wisconsin.

✅ White bass fishing is at its best in the late afternoon and through the night. We have had great success trolling Spoonplugs right next to the shore. The best way to locate stripers (white bass) is to troll. This is especially true in the river. Work one side of the shore, then the other until you hit the main channel.

✅ We have had good success using a 3 way swivel and the No. 500 (tiny) Spoonplug trolled right off bottom. (River rig)

✅ Another hint that may come in handy here or elsewhere: Sometimes you may have anchored in deep water in the river. Boats around you may be getting fish and you are not. Usually the trouble is that you are in water that is too swift. If this happens, then move so you can fish the EDGE of the sluice.

✅ The lake itself is very shallow, maximum depth 6-8 feet. There are a few deeper areas where the Rock River flows in and out. Because of the river it is an excellent lake.

✅ Koshkonong is an ideal lake for Spoonplugging (casting the Spoonplug) because much of the bottom is sand or gravel. We find Brass, Red and White, and Silver Spoonplugs best. Jigs, French Spinners, and Streamer Flies (Silver Minnows, Mylars) are excellent, too.

✅ This lake is big, nine miles; it gets rough so watch out. Most anglers fish the lee shore or, if too windy, they go into the river.

Could you do the same for your lake?
