never fished little squam, but the way I approach any new lake is to look at satellite view, mapping s/w, & state bathy maps.
satellite gives you good idea on access, water clarity, shallow structure (google maps>satellite view or google earth)
mapping s/w gives you deep structure: points, humps, holes, saddles, inside turns, etc. (webapp.navionics.com or download the app)
bathy maps help confirm mapping s/w (both not always accurate) & gives added info on fish, stocking, etc.
there's some good looking stuff on little squam....and it sticks out like a sore thumb....
good luck!
