I don't summer fish for trout- some guys do- if you do- invest in a thermometer
The state stocks lightly in fall

The Wanaque, Ramapo and rockaway river are all about 25mins from Elmwood park- all are lovely rivers- lightly stocked- the musconetcong and paulinskill are much larger- and better stocked- prob 45 min and 1 hour respectively. I'm partial to the paulinskill in coulmbia- by station road-
The black and rockaway rivers aren't too far from mendham but I haven't fished much there.
The deleware is lovely- massive- I don't fish it- many guys do-they recently met up and went after flatheads. A friend (non nj fishing ) did well on smallies in the upper region above walpack.
For warm water, the Passaic river upstream from you has a large variety of fish- guys here hit lmb smallies and some pike way up- there are some cats in the two bridges section of Lincoln park(15-20 min)
Small bodies of water can be very productive- as big bodies (monksville res. Greenwood lake) just be cautious of private property-
As for by mendham- cranberry lake and lake aeroflex in Andover are nice on the boat- lake hopatcong is too- but has heavy pleasure traffic over the weekend-lh does have hybrid bass
Feel free to pm with questions- tight lines- and let us know how you do
