Young Lake

Crow Wing County, MinnesotaMesotrophic

Young Lake sits at the top of the Minnesota PCA grading rubric with an A, a mark reached by the cleanest lakes in Minnesota. The two scored sub-grades — clarity and phosphorus — track close together, so neither one is dragging the average down.

The lake sits in the mesotrophic zone — the band where most well-managed Minnesota lakes fall. The lake bottoms out at 21 ft — a moderate depth that supports a warm-water fishery without the year-round cold refuge a deeper basin provides. Young Lake is small — 67 acres alongside 1.7 miles of shoreline — which makes it sensitive to even modest changes in watershed runoff or recreational pressure. Within Crow Wing County's 120 graded lakes, Young Lake ranks 72 — below the local median, though not at the bottom.

No invasive species are currently listed at Young Lake — the lake remains off the Minnesota infested-waters roster. The state fisheries records do not list documented species for Young Lake, which usually reflects a lack of formal fisheries survey work rather than an empty lake. The lake lacks a documented public access point, so visitor use is limited. 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.

DNR Fisheries Survey Summary

1 survey on file from MN DNR Fisheries. Most recent: 1992-06-15 (Standard Survey).

Top Species by Catch Rate

SpeciesAvg CPUEAvg Weight

Brown Bullhead7.880.23 lb
Northern Pike7.132.54 lb
Black Crappie5.000.08 lb

CPUE = catch per unit effort, averaged across surveys (excludes juvenile shoreline seining). Higher CPUE = more abundant in standardized sampling.

From the 1992-06-15 survey

NOP AND BLG WERE ABUNDANT, GOS AND YEP WERE PRESENT IN LOW NUMBERS. ALL OTHER SPECIES WERE CAPTURED IN AVERAGE NUMBERS FOR THE LAKE CLASS. NOP (12.0/GILLNET) CATCH WAS HIGH. AGES YY-IV AND VI-VII WERE PRESENT. THE 1988 AND 1989 YEAR CLASSES CONTRIBUTED 42 AND 33% TO THE CATCH, RESPECTIVELY. GROWTH WAS GOOD FOR ALL AGE…
