That'll be a great time. I'm from there. My recommendation if you like casting is big Williams Wablers (silver or gold; depends a bit on the water colour and local forage) and Husky Jerks (silver and blue or silver and black). Len Thompson spoons can work well too in classic red/white, five diamonds or perch patterns. They cast a mile and sink fast. Big spinners (#4 or #5) can be great too.
I would guess that in mid-June in that area you could just pick a spoon and cast it anywhere and catch fish all day. It's definitely nice to find the one that's working best. But finding fish should not be a problem. A chance at a 15-20 lb fish is possible too, depending on the lake. If you're a more relaxed fisherman, just get a couple dozen large minnows and put them under a float anywhere there's some obvious structure (large shallow bay with some cabbage weeds would be prime).
Also - I'm not an advocate of taking advantage of spawners - but bass season is open all year there. So catching big fat protective males on patches of rip rap or gravel is super easy. And mid-June is probably you best bet in that area. I'd highly recommend letting any bass go at this time of year though. They're guarding their nests for a reason.
Thanks for the info. We will be based on Lost Lake near Elk Lake We are heavy conservation and these lakes appreciate that
