Highland Lake Fishing near Round Lake Park, Illinois

• Overview

  Highland Lake is one of the Lake County listings for Illinois. The setting is lake country bush on every side. The water covers some 101 acres, so pick a bank rather than trying to cover it all. Around 1.5 miles of margin, front to back. It is high ground by Illinois standards. 0.8 miles away sits Round Lake Park, the nearest town. Then Hainesville, 1.2 miles, and Grayslake, 1.6 miles. This one sits near enough to a boundary to be worth checking.

• Where to Fish on Highland Lake

  Open data we checked carries no depth for this water. A soft bed grows weed late into autumn, which keeps fish shallow. A natural lake fishes on cover, and cover here means weed and timber. Across Lake County, recorded fish include bluegill, common carp, green sunfish, pumpkinseed and largemouth bass. Records at this level tell you what is in the area. The shape of Highland Lake rewards a slow walk along one bank.

• Seasonal Patterns

  Expect July to average close to 72°F, with January the cold end at about 20°F. Cold winters and warm summers give a wide working range. Count on hard cover from midwinter, and open water from late March. Open water usually runs from late March until about mid December. The strong weeks are the first after break-up and the last before the freeze. Highland Lake runs to its own calendar within the local pattern.

• Tackle & Baits

  No access rule appears in what we hold. No dam controls it, and the level follows the season. You will be walking about half a mile from the nearest car park. Somewhere to sit and eat is half a mile out. Largemouth respond to soft plastics tight to cover; go weedless where the growth is heavy. Bank access can be seasonal on ground like this. Night access is frequently treated as a separate matter. Cranberry Lake at 0.7 miles is the sensible second choice. Signs at Highland Lake carry more weight than any list.
