Lost Lake vs Plum Lake
Water quality, depth, fish species, and recreation comparison.
Plum Lake reads lower on nutrients and algae than Lost Lake. Both are in Vilas County, Wisconsin.
Lost Lake and Plum Lake are both in Wisconsin — a same-state head-to-head where the comparison comes down to lake-specific differences in depth, watershed, and monitoring history rather than the broader state-level water-quality regime. These two sit close on their nutrient and algae readings, Lost Lake versus Plum Lake. The deciding factors for a recreational visitor are likely physical (depth, access, fish species) rather than water-quality differences.
With readings this close, the choice between the two lakes turns on non-water-quality factors: depth, fish species, public access, distance from home. The per-lake pages below cover all of those.
