The 2018 Regs are out on paper although not yet on the internet that I can find.
Major changes in Banff National Park as a number of Lakes and flowing water streams are closed.
This is to monitor the Lakes for Whirling Disease as these waters contain BNP'S only populations of pure strain Native Westslope Cutthroat Trout.
Included on the list as closed to fishing this year are the following lakes... Sawback ,Rainbow , Mystic and Marvel.
Hopefully all the testing is concluded this year and the Lakes are back open next year but then again who knows how long this process will last.
I fully support this as being a prudent decision by Parks. But of course we will watch closely to see how things progress...
