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.

Catch per net (CPUE) is the DNR survey's count per gill net or trap net set; higher means more of that species were sampled, not a fishing forecast. Top species per gear shown; where we have no verified common name for a DNR code, the code itself is shown.
Pine Lake (also known as Trestle-Pine Lake) has been managed for stream trout since at least 1951. From 1988 through 2010 the lake was stocked annually with Splake fingerlings and Rainbow Trout yearlings. Rainbow Trout stocking was discontinued after 2010 to reduce management costs; however, the loss of that fishery was felt by summer anglers, and Rainbow Trout stocking will resume in 2020. This was the first of three standard surveys scheduled in the current (2018) lake management plan to evaluate that renewed stocking, and detemine what effect the accompanying reduction in Splake stocking (beginning in 2019) will have on that population. Splake appeared to have been abundant in 2018, with many 10-13-inch fish present. The Splake gill net catch in 2018 met the goal from the current plan (a minimum of 5.0 fish/set, with some fish over 16 inches). The catch was similar to those seen in this lake since 1998, and was well within the normal range (5.0-12.0 fish/set) for spring catches in stream trout lakes in this area. The trap net catch was the highest seen to date in this lake, and was above the normal range for this area. Splake collected in all gears in 2018 ranged in length from 6.0 to 18.0 inches, with most in the 10-13-inch length range. Five year classes contributed to the 2018 catch, including a few fish from a 2017 year class that appeared to have been naturally produced. Splake growth appeared to have been slow. Fish reached a mean length of just 10.4 inches at the end of their third year, compared to an area mean of 12.8 inches. Slow Splake growth has been noted in this lake in the past, and may have been due to the high numbers of fish present, and competition for invertebrate forage from White Sucker and Bluegill. Bluegill numbers were fairly high (for a lake in this area) in 2018, and the survey catch included many that would have been large enough to have been of interest to anglers. Bluegill were first taken in a survey of this lake in 1998. The 2018 trap net catch, while not unusually high for a lake of this type, was high for a stream trout lake (or any lake) in this area. The catch included many larger fish (up to 9.8 inches in length). Seven year classes contributed to the 2018 catch, which included fish as old as nine years. Bluegill growth had been about average for this area, with fish reaching a mean length of 6.9 inches at the end of their fifth year. Reproductive success appeared to have been consistently good, although no year classes stood out as having been exceptionally strong. The 2018 White Sucker gill net catch was the…
