Depending on where you are, in Texas, most of the ponds here are stocked with catfish and bass. – ma

The golf course by my house has bluegill, bass, and catfish. One of the two ponds have carp over 3 ft. in it.

Bass bluegill and probably grass carp, The carp will get big they have them here in Fl for weed control , I have been catching some 3 feet long on plain bread

For bluegill use a nightcrawler

for Bass i would try a plastic worm .

Its likely you will catch some fish

Additional advice … get permission , dont trespass

and
Dont keep or eat the fish there Golf Courses use lots of pesticides and fertilizers on their greens and grass which runoff into those lakes and the fish absorb those toxins

They stock bluegills and bass in the ponds most of the time!They are doing weed control differently now and have been staying away from carp around here they found some of the small ponds muddy so bad because of the carp.
I fish them and yes u can get some big fish from them but dont keepem all!A small pond can be over fished by one person real fast!

Bass, catfish, crappie, etc. I went fishing at one the other day where someone caught a 29 inch catfish and I caught a 18 inch, 3 pound largemouth bass

don’t listen to them me and my grandpa study fish and own a bait shop and the small fish you are seeing are perch and there is likely to be bass and maybe catfish

catfish and blue gill is about all you may expect.

Do you live in the north where there is ice on the lakes for more than two months? If so you will most likely find only small fish as the larger ones will die of low oxygen levels first.

If you live in the south, I wouldn’t be suprised to find some decent sized Bass or panfish in them, but there is likely not a population of Northern or larger game fish.

Start with live bait, nightcrawlwer, under a bobber. That will tell you immediately if there are panfish in the area, plus a bass or bullhead will like that presentation too. If you catch a Bass, experiment with some topwater, or a slow, shallow diver. If it is weedy, cast right on the edge and you should get results.

if in the midwest problem carp and catfish and maybe a bass or two

i wouldn’t advise doing what you have planned,if you get caught you would be considered a trespasser end up in jail and lose all your fishing stuff
