Being from NY here are some of my observations on vegitation in the bodies of water I fish that may help you once you have ID'ed what your looking at:
Submergent veg:
Milfoil = bass.......... if it's green and healthy. Once it turns brown and slimey, and looks like "rust" falls off it when you hit it with a lure, get away from it, as the bass have left it. Milfoil takes it's sweet azz time getting going in the spring, as it really likes nutriant rich, warm water, and a cool dry spring seems to keep it down.
Deep water coontail = bass. This stuff stays green in even the nastiest water, and way late into the year. There is ALWAYS life around it. Like Milfoil, it takes a while to get going in the spring, but by late summer it's usually pretty thick, and stays thick and green longer than the milfoil.
Curly leaf pond weed = bass......... IF milfoil and coon tail are not available, but if they are, they really seem to prefer the milfoil and coontail. On my lake this weed is the first one in the spring to "take off' and get lush...as it seems to like really really clear water, and cooler temps. But then it wilts and dies in early summer when water temps start rising and when the water starts getting a little color in it, and is replaced in the depths it grows in by milfoil and coontail.
Eel grass.........avoid it. They NEVER and I mean NEVER seem to be IN the eel grass, but will cruise the edges of it. At some point in late summer/early fall eel grass uproots, and floats, and makes floating mats...........sometimes they get under it, but they still don't seem to care for it much.
carpet weeds........like chara, coon tail moss (looks like deep water coon tail, but just grows close to the bottom in shallow to mid depths)....never seem to be many bass around this stuff or in the area it grows as it mostly grows on soft mucky bottoms
Elodia.........looks like hydrilla, but it ain't, and I rarely find bass in or around it
Emergant veg:
Pads of all sizes............they all hold bass if there is enough water under them, and the bottom under them is to the bass's liking.t
Cat tails......... they typically grow in muck, and other than the odd hard bottom areas that intersect with them , I rarely find them to be productive.
