Quite a few sub-surface crypts, sunken ships and even submerged forts in which to find things.
Swim safely up until you sart to lose health, no breath meter sadly.
Easy way to level-up restoration also: swim till damaged, surface before dying. go to shore, heal, rinse, repeat.
For some reason there is also a lot of various Ore seams around lakes.
LOTS of fish, salmon for food, clams etc, various small fish as reagents, barnacles etc, plus slaughterfish to fight: although you need to go to the shore to fight them (they will follow you).
You'll also find quite a lot of wildlife running around the bottom of lakes, deer, elk, rabbits etc... go figure
Havent managed to lure a dragon under water yet, working on it..... ?_?
