My Father used to fish a lot on Macintosh. He had a hard time finding any large fish, so he goes to Jordan most of the time. After you leave the landing and go under the bridge, start looking for beaver lodges about halfway up the lake. A number of the coves to your left and right will have a lodge in them. You can throw jigs or minnows under corks. Good luck and maybe you can find some of the large ones.
