I have fished Maligne Lake earlier in the year but George at Online in Jasper said that he did some chronimiding and did very well in only 3 hrs just not sure what he said for numbers 30 + .. if trolling Raps you could have a great day in spots
On Medicine Lake ..its very fish able same way or even trolling ..as I used too do in 1967 as a youngster .. I have done it a few times since and did well ..but when the lake starts to drop in Sept and you can walk across the flats to the river that's when to fish Medicine
