Casting water walking while swimming causes fall damage
Some time ago there was a fix to Bug #1138 (closed) which recreated the behaviour of Vanilla Morrowind regarding Water Walking.
If you cast Water Walking while swimming near the surface, it should allow you to walk on the water.
In the current version 0.41, casting Water Walking while swimming, puts you on the surface and causes you to enter a twitchy "falling" state.
When you reach the shore, you die due to fall damage.
