Field note · Minnesota stocks by year, not by truck day: walleye fry go in within weeks of ice-out, fingerlings and yearlings mostly in fall, and stream trout in spring and fall. A row here means the fish went in during that year; DNR adds the year's rows after the fact, so the current year can look empty until winter.

DNR fish survey, 2025

Minnesota DNR Fisheries IBI program staff conducted an assessment of lakeshore habitat on Crystal Lake on September 4th, 2025, following the Score the Shore survey protocols. The assessment consisted of 49 survey sites evenly spaced 70 meters around the lake. Assessments were made in three habitat zones: Shoreline Zone (the shore-water interface to the top of the natural bank), Shoreland Zone (land-ward from shoreline to development structure or 100 feet), and Aquatic Zone (lake-ward 50 feet of shoreline). The average lakewide habitat score was 62.5 (+/- 3.7) out of 100 possible. A score of 62.5 indicates the lakewide shoreline condition is Poor (50-65.9). Approximately 78 percent of the sites were developed with a mean score of 53.2 (+/- 3.6) indicating shoreline habitat quality of developed sites is Poor (50-65.9), while undeveloped sites had a mean score of 94.5 (+/- 1.8) with Excellent (92+) habitat quality.
