To be honest, last year was pretty brutal for Muskies on the DF, at least it was in my boat, it turned on late season but all of summer was really tough.
I was up this last weekend and landed a 30+ incher and had another small one follow up. It was quiet over all but much better than last year already.
In my experience brighter colors do well on this lake, if its a sunny day use a copper blade. Contrast is key here with the heavy stained color of the water, vibration, rattles, and loud topwaters are all good choices. The main forage is Redhorse, White Sucker, Emerald Shiner, ect, so you should keep this in mind when chosing color combos to throw.
Protip: fish the mooon phases (rise, set, above, below)
With almost all types of musky fishing, key in on weed areas adjacent to deep water or open water, these have always been my top producers on this lake. I know some people do well trolling for them as well if you're into that kind of thing.
Weather plays a MAJOR factor on this body of water, if you're weekend falls in the middle of a low pressure cold front, be prepared to adjust you're gameplan. If the weather and wind are fairly steady leading up to your excursion, I would be optimistic.
3 Large areas that consistently hold fish: - The Island - The Old Marina - The Horseshoe
There are tons of other structures and all kinds of intricate little spots that hold fish, this really is a great action lake and if you're putting in a lot of time on the water you should at minimum see some fish.
One last thing, put 'em back
