Lake Shangrila -Benet
Kenosha County, WisconsinEutrophic
Lake Shangrila -Benet earns a D — measurements through 2022 show persistent nutrient pressure that limits clarity through the summer. Secchi readings are the weakest of the scored parameters, suggesting suspended sediment or algal biomass dominates the optical signal.
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 10 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. 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.
