17,502 in 60 days: Derby cuts Flathead lake trout population

It took David Myers just 60 days to catch 2,822 lake trout in Flathead Lake this fall. 

Myers, of Riverton, Wyoming, took the staggering haul on his way to victory in this year’s Fall Mack Days fishing derby. Myers fished each of the event’s 60 days, which ended this past Sunday. He averaged 47 trout daily. Although the event ran nonstop for nearly two months, only Fridays, Saturdays and Sundays were competition days. Myers’ 1,399 trout on those days bested the 343 other Mack Days anglers; his 18-day average was 61.61 pounds of trout daily during competition days.
