Having a cabin near lac du bonnet I fish the area quite frequently both open water and hard water. The Winnipeg river, and Lee river are both packed with fish, just as previously stated finding them at the time of year can be a bit tricky. Mcarthur falls is by far one of my favorite places to fish, this year tho for both bait and fishing has been poor. Ive caught 1 master, and a few other odd big walleye ranging all over the 20'' mark but compared to other years its been really poor. The goldeye have barely been running there, seen more ciscos this year than mooneye or goldeye.Goldeye have been biting well on the winnipeg river from the narrow bridge to the high side of the mcarthur falls generating station, try anywhere along the dike i usualy go 6-10 feet. Great falls is also producing goldeye on the low side of the damn.
Lee river has a couple good spots to fish but one spot thats actually pretty consistant to whether you catch is the pinawa channel. The second bridge on 313, fishing downstream under the bridge with a jig or lindy rig can be pretty productive. If you can catch the minnows under the bridge use them for bait, if not i find night crawlers work best here. Over a couple hour period you can catch multiple species. If your fishing by boat, your chance of catching a fish will go up tremendously. If you can get bait out of these bodies of water your success will go up that much more.
If i knew how to attach pictures i would but i dont honestly know how lol.
