Its fish on the CPW roster: brown trout, cutbow, kokanee salmon, rainbow trout, largemouth bass and walleye. Boaters have 2 boat ramps to choose from. CPW sets the boating rule as Motor boats (gasoline). The Fishing Atlas rates access as easy and fishing pressure as low. Through the ice season: ice fishing listed as yes.
CPW Quality Waters: Variety angling in a single park, each pond really has something different to offer. Exceptional for families and new anglers and great ice fishing. Park staff is quite incredible with a breadth of fishing knowledge. Blue Heron Pond has excellent largemouth bass, great for walleye/saugeye, channel catfish, crappie, and redear sunfish. This is the largest water on the park and trailered boats can launch.
