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
Divide Lake is a designated stream trout lake that is stocked annually with yearling Rainbow Trout and fingerling Splake. A survey was completed in 2025 to monitor the amount of cool, well oxygenated habitat available for trout during the summer. Automated temperature loggers were suspended at depths of six, twelve, and eighteen feet below the surface over the deepest spot in the lake to record hourly water temperatures throughout the summer. In addition, temperature and dissolved oxygen profiles were collected on several occasions to determine how deep well oxygenated water occurred. Survey results indicated summer dissolved oxygen concentrations and water temperatures likely caused stress to the trout in Divide Lake in 2025. Similar surveys completed since 2015 suggest periods of stress are common in summer months, but the lake currently maintains suitable habitat for stream trout throughout the open water season. Habitat conditions will continue to be monitored to evaluate the suitability of Divide Lake for stream trout management.
