Ryan?

Hmmm. Looks like it could be pretty much anywhere south of the Boreal forest, but this is an Algonquin forum, so.... A lake, some trees...white pines, cedars, I think I see some birch, no obvious jack or red pines...okay west side of the park maybe...the sun is behind you, you're looking at the north shore of a roughly east-west bay or lake, wind from the west, but I'm wondering what would have driven you to take this photo...there's no obvious feature.  Hmmmm, I'll say "What is the east end of Louisa, Alex?".

I could add that the picture was taken from the only campsite on this lake

Not Cayuga. 

Baby Joe Lake?

lol I was going to say Lantern first, but the shoreline looks a little off..

Is it Lantern?

Here's the campsite

Not Hayes. This lake is not a low-maintenance lake.
