With the ice deteriorating and the ice shacks removed, recreational fishing is closed until May 14. As anglers prepare for the coming spring and summer fishing season, Alberta Environment and Parks and the Fish and Wildlife Policy Branch took stock of the lake and made decisions on size limits.
Senior Fisheries Biologist, Jason Cooper, and Fisheries Scientist, Michael Sullivan provided some background on the fisheries management objectives for Sylvan Lake for this year.
According to a report used for a consultation process last year, the current concern for Sylvan Lake is the overharvest of Walleye and Northern Pike.
