Pokegema Lake Deep

Pokegema Lake Deep comes in at a B on the grading rubric — a respectable showing for a Wisconsin lake of its size and depth. Sub-grades cluster within a single letter of each other, which usually means the lake is in stable trophic balance rather than fighting one specific stressor.

Mesotrophic conditions dominate at Pokegema Lake Deep: enough nutrients for a healthy fishery, not so much that algal blooms become a chronic problem. At 65 ft of maximum depth, Pokegema Lake Deep stratifies reliably through the summer — the hypolimnion stays cooler and clearer than the surface layer suggests. At 1,041 acres, Pokegema Lake Deep is one of the larger lakes in Vilas County, with partial shoreline records supporting multiple distinct use patterns. Pokegema Lake Deep sits at rank 108 of 191 in Vilas County, in the lower half of the local distribution.

Pokegema Lake Deep has at least one documented invasive species (Chinese Mystery Snail), so boaters and anglers should observe clean-drain-dry steps when leaving the lake. Walleye are documented at Pokegema Lake Deep, one of 6 fish species on record for the lake. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
