Lake Seventeen
Oneida County, WisconsinLimited DataMesotrophic
On the LakeGrade scale Lake Seventeen grades a B, with clarity at 12.0 ft and phosphorus readings still being added placing it above the Wisconsin median. 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.
The lake sits in the mesotrophic zone — the band where most well-managed Wisconsin lakes fall. A maximum depth of 37 ft puts Lake Seventeen in the middle of Wisconsin's depth distribution. At 176 acres, Lake Seventeen fits the Wisconsin median for monitored lakes, with partial shoreline records. Lake Seventeen ranks 43 of 134 in Oneida County — solidly in the upper half of the local distribution.
No invasive species are currently listed at Lake Seventeen — the lake remains off the Wisconsin infested-waters roster. Walleye are documented at Lake Seventeen, one of 6 fish species on record for the lake. 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.
