i fish ahmic a few times a year, its a beautiful body of water. Its tough fishing sometimes thoguh in the summer. There is rainbow smelt in the lake so you have to fish deep to get walleye in the summer.
The first thing i would do is go to magnetawan bait and tackle and get your bait, ask for some tips while you are paying for them and im sure they will point you in the right direction. failing that find the rainbow smelt and you will find the walleye. In the summer since smelt are light sensitive they are deep, im not sure if that changes because of the ice or not.
Hope you do well on ahmic and look forward to the report!
Cheers!
