DD,
You are gonna need the cheap aluminum framed dip net and an old broom handle. Cut off the old broom handle and insert into handle of dip net. Tada you have just created a wading dip net. This serves 2 purposes, one is to dip net the fish you catch, the other is a bottom probe so you can test the bottom for depth, and to see if you are stepping in some kind of super soft silt. Also, since the handle is wood it will float when you drop it.
The drink thing will not be an issue. If you start getting hot and thirsty, the water is too warm for them to be in there, might as well go back to the boat and find some cooler water.
You forgot the most important thing you need to carry and keep dry. Some blue towels. It never seems to fail, get settled in and nature calls. And when nature calls you GOTTA ANSWER THE PHONE!!
