Yes, I have found the same. Some of the pools are so close to shore, they are half-circles. Those are a waste of time to fish - I have tried them from every angle. Some of the others that say "too shallow" can be fished with persistence. As said above, wade out a bit and try from different angles.
Good Luck!
