Lake Shangrila -Benet

Kenosha County, WisconsinEutrophic

Lake Shangrila -Benet sits at a C on the grading scale — not impaired, not pristine, with summer measurements that vary year to year. 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.

A TSI in the eutrophic range signals a lake doing what nutrient-loaded waters do — supporting an active algal community at the cost of clear water. A maximum depth of 24 ft puts Lake Shangrila -Benet in the middle of Wisconsin's depth distribution. The lake's 110 acres and partial shoreline records put it in the mid-range bucket — large enough for varied use, small enough that watershed inputs reach the whole basin. Lake Shangrila -Benet ranks 11 of 13 in Kenosha County — at the lower end of the locally monitored distribution.

Zebra mussels have been documented at Lake Shangrila -Benet, which alters the filter-feeding balance and can paradoxically increase water clarity while disrupting the food web. The state fisheries records do not list documented species for Lake Shangrila -Benet, which usually reflects a lack of formal fisheries survey work rather than an empty lake. A documented public access point at Lake Shangrila -Benet makes the lake usable for shore fishing, paddle craft, and trailered boats. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
