Have you tried going to Joseph grant park and checking out the lake. I remember I went there years (10+) ago to do some fishing for some largemouth and I would always get snagged on all of the plants that were in the lake (not sure of species though, might be common pond plants, might not be since I had no knowledge of aquatic plants back then). I used to get a lot of bluegills there also that I put in a native tank back then.
Not sure about now, because I remember they pumped out water years after I went, to get rid of some of the evasive species that somehow got in there. it's a cool place just to check out and take in the scenery though. Just watch out for rattlesnakes, I've ran into many of them while trekking around the lake.
