Lower Clear Lake

Lower Clear Lake comes in at a B on the grading rubric — a respectable showing for a Wisconsin lake of its size and depth.

Mesotrophic conditions dominate at Lower Clear Lake: enough nutrients for a healthy fishery, not so much that algal blooms become a chronic problem. A maximum depth of 21 ft puts Lower Clear Lake in the middle of Wisconsin's depth distribution. At 79 acres, Lower Clear Lake sits below the Wisconsin median: a small water where shoreline activity has an outsized effect on water quality. Lower Clear Lake ranks 12 of 32 in Langlade County — solidly in the upper half of the local distribution.

Lower Clear Lake has no invasive species recorded in Wisconsin state databases as of 2025, though prevention practices still apply at all access points. The fishery is bass-led, with 2 documented species across the lake's records. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
