I've been to Murray Hill pond quite a bit myself, there are some nice sized bluegill in there. Best spot to fish is the super shallow end of the lake that's muddy, the part with the fountains doesn't hold many fish, it's really deep and clean. The muddy part is about 2-3 feet deep and is filled with carp, bluegill, and maybe something else?
Btw-Watch out if you're fishing with night crawlers. May hook one of the pet turtles that lives there
Yeah universalfishermatt, fishing is allowed there (as far as I can see). I went there daily for a couple hours for a month, nobody apprehended me or anything. Plus, there's no "no fishing signs". Also, I've encountered a few other fisherman there, and they didn't say it was illegal to fish there.
Murrayhill is managed by CMI and not a "park" so while it may be allowed, it could quickly not be allowed. All that has to happen is one business to complain and signs will go up. So be respectful, pack out your trash and be discreet if at all possible.
I only say all of this because I have fished there and had a lady yell at me because I could possibly hook a duck or turtle. She claimed I could not fish there. I did my homework and made some calls and got a "there are no rules that say you can't fish there, but there isn't anything that says you can", so again, play nice while there or very quickly no one will be allowed there.
I have picked up a lot of fishing line, bags, cans and seen a lot of trampled bushes.
