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 value of 32 puts Moss Lake West Deep in the oligotrophic range, where biological productivity stays low and the water column remains clear. Moss Lake West Deep reaches 29 ft at its deepest point — typical for Wisconsin mid-sized lakes, with seasonal stratification but limited cold-water refuge. Moss Lake West Deep covers 185 acres alongside partial shoreline records — a mid-sized water that supports a working fishery without being so large that conditions diverge between basins. Moss Lake West Deep sits at rank 106 of 202 in Vilas County, in the lower half of the local distribution.

An invasive species record — Purple Loosestrife — has been logged at Moss Lake West Deep; Wisconsin DNR maintains the official infested-waters list. The fishery includes walleye alongside the lake's other 6 documented species — a notable draw for Wisconsin anglers. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
