You should be fine fishing from the bank. Wading is generally not desireable in those mountain streams anyway. All that rock crunching and pushing a wake alerts the trout. Sure, you will not be able to cover all the water, but that's probably true anyway. Practice your sidearm cast so you can stay below tree limbs. Shallow water can be dangerous. A fall in six inches of water can hurt you. A fall in two feet of water gets you wet. Take a partner with you for extra security. If you look at a lot of the posts, you'll see most of these folks are fishing from the bank. Good luck.
