Unexpected Lake Muskies

We've been told Unexpected lake is an awesome lake to catch some good sized muskies 50"+. I guess we'll find out this season as we've booked the trip. It is located in NW Ontario as the top part of the English River system. Past guests have said its totally awesome with walleyes, northern pike and some smallmouth bass fishing to boot.
Should be fun. If anyone has tried thhis lake please let me know what you thought of it.
Thanks

Dont you guys mean Hauser Lake in Idaho...not Hayden lake for tiger muskies in Idaho? If there is another lake that has tiger in them called Hayden, please do tell...
