Deer Park is hit, or miss.
I used to fish it regularly. There are some big fish in it, but they are hard to find.
I'd say that if you had a sonar and some good equipment, it might be what you are
looking for. I wouldn't ice fish it alone though.
They do have some pretty good sized gills and perch in it, but it's a lot of work.
I would probably hit Hopatcong State Park before I would attempt Deer Park.
That's just me. I'm a little on the lazy side.
