Berry Lake

Berry Lake carries a solid B grade — strong on most parameters, with measurements that hold up well across the summer season. The lake's weakest score is on Secchi depth — the water looks more turbid than its phosphorus number alone would predict.

Mesotrophic conditions dominate at Berry Lake: enough nutrients for a healthy fishery, not so much that algal blooms become a chronic problem. Berry Lake reaches 27 ft at its deepest point — typical for Wisconsin mid-sized lakes, with seasonal stratification but limited cold-water refuge. At 209 acres, Berry Lake fits the Wisconsin median for monitored lakes, with partial shoreline records. Berry Lake sits at rank 35 of 62 in Oconto County, in the lower half of the local distribution.

Berry Lake carries an invasive watermilfoil record — boat-launch decontamination and shoreline care matter more here than at uninfested lakes. The fishery is bass-led, with 3 documented species across the lake's records. A documented public access point at Berry Lake makes the lake usable for shore fishing, paddle craft, and trailered boats. Monitoring depth is thin here: the LakeGrade rubric is applied to a small number of sample years, and the grade will be revised as more data accumulates.
