Lake Superior lake trout harvest

Fishing Wisconsin

Lake trout are a popular target in the Lake Superior fishery.

The Lake Superior Lake Trout Season opens on December 1 and closes the following September 30. However, Lake Trout are managed based on a safe total allowable harvest or quota system. When the recreational total allowable harvest is approaching the season may close prior to September 30. This page is designed to be updated periodically for fishers to track the harvest and explain the regulation.

Lake trout sport angler quota calculation

The lake trout sport angler allocation for WI-2 during the 2019 and 2020 fishing season is 17,000 fish. Angler harvest is monitored with the use of a creel survey and mandatory charter captain reports. A harvest trigger has been set to prevent overharvest of lake trout. When the 12,800 fish trigger is reached, lake trout fishing in WI-2 may be immediately closed, with no more fishing for lake trout. The trigger was set to account for delays in data processing during times of potential high harvest.

Lake Superior lake trout management

Lake trout harvest zones


The lake trout in Lake Superior are managed within two harvest zones (WI-1 and WI-2). Lake trout numbers declined in the WI-2 zone – the Apostle Islands area of Lake Superior - during 2003 to 2012.  As a result, harvest quotas were reduced for sport and commercial fishers. 

How was this regulation selected? Over the past several years, Fisheries Management has asked anglers for input regarding various lake trout regulation options. In the fall of 2017, anglers participated in a poll that included four different bag and length limit options (see below) and the associated risk with each option reaching the quota before the end of the season (September 30th).

Results from the survey indicated a majority of participants supported a regulation that included a bag of two lake trout with a 15-inch minimum and one fish that could be longer than 25 inches.  This regulation option allows the greatest harvest opportunity but also has a moderate risk of reaching the quota prior to the end of the season.
