Upper Passaic River (Florham Park)???

[Skunk City]

Well I started my new job yesterday in Florham Park. While sitting at my desk on break, I decided mess around on Google Maps to see what's in the viscinity, as I am from Northern Jerz and don't know the area too well. Sure enough, directly behind my office building runs my favorite river, the beautiful Passaic.

Now I have fished the river tons of times from Fairfield, through Two Bridges, and even the tidal area below the Dundee falls, but never as far upstream as Florham Park. I most definetly will be tossing my 'yak in there as soon as this rain ends, but what should I be targeting? Bass and Pike are my focus in the Two Bridges area, but what type of fish are upstream that far?
