Locating walleye, Need some advice

[Donny135]

Although I'm not actually fishing Nipissing I figured it's a good place on the forum to ask. I'm just wondering what I should be looking for to find walters this time of year, flats, ruble, drop-offs, weed lines? My past two outings I've been fishing a drop-off that's also a bit of a weed line but to no avail.

Any tips would be much appreciated,
Donny

Weed flats work for me 18- 22 ft
