there's a million ponds and almost as many brooks and streams in morris county. they all have fish in them. as was suggested take a look at the NJDFW access points pages at
http://www.state.nj.us/dep/fgw/fishplc.htm#morris
http://www.state.nj.us/dep/fgw/fishstrm.htm#morris
also, check out the WMAs in the area
http://www.nj.gov/dep/fgw/wmaland.htm
many of these have streams, ponds, etc on them. you can fish them any time you like, but to be courteous and avoid ruining hunts for people it is best to stay out of them later on in the year when waterfowl and deer seasons are open
ask if you have any more specific questions
