The Wisconsin Department of Natural Resources is celebrating a major milestone this month. June 20th marks the 80th anniversary of the Northern Highland Fishery Research Area in Vilas County, one of the longest-running fisheries research projects in the world. Since 1946, researchers have used five Northwoods lakes to study fish populations, angler behavior, and conservation practices. Current projects include studying fish habitat, the impact of forward-facing sonar, climate-related changes to lake ecosystems, and walleye population trends. The research continues to help guide fisheries management across Wisconsin and beyond.
