RE: under water elevations
This depends on the accuracy and sounding density requirements, the width, depth and current velocity of the water body. I have done a fair bit of river hydro-work with both single beam systems and sounding rods / chains. This sounds like a sounding chain problem. I would be more than willing to help with some more details about the river.
