St. Croix River, Cass Lake

I'm a novice fisherman, just got started with a spincaster in July and
would like to learn more about fishing (particularly bass). I'm
taking a crash-course, learn-as-you-go approach as I'm also trying to
teach my 4 year old how to fish. Every experience is worthwhile. I'm
based out of Stillwater MN and would like to try fishing the St. Croix
river from shore. Any advice on species in the St. Croix, the type of
set-up I will need, good spots on the shoreline etc are appreciated.
I will also be heading up to an island at Cass Lake later this month,
so any advice for that area is also welcome.

Cheers,

Alan
