Popular Fish Species Castle Rock Lake, WI
Walleye
Thanks to good fisheries management by the Wisconsin Department of Natural Resources, a quality population of walleye abound in the waters of Castle Rock Lake this year. May and June tend to be the best time for weekend anglers to catch them. During this time they tend to move shallower and closer to shore. Other times of the year they are more likely to roam around in deeper water. As always, staying close by schools of baitfish. They are eager to feed throughout the lake, but tend to concentrate around structure on points, flats and ledges off the river channels. A proven method for catching walleye here is trolling with spinners tipped with live bait, or trolling with long-billed, deep diving crankbaits. However casting live bait, jigs, worms and spoons also works well at times. When the lake freezes over in winter, ice fishing for walleye can be very productive. Use GPS to locate spots you normally fish during other times of the year.

When crappie fishing in Castle Rock Lake you can catch both black crappie and white crappie. The two species reside here in good numbers, and often school together.

In spring and fall focus on the 8 to 12 foot range. As the crappie move deep in summer and winter, follow points out deep, as well as find ledges near channels in deeper water. When the lake freezes over, ice fishing is often a great way to catch a quick limit of crappie.
