This grade is the height to which a column of water would rise in a Pitot tube (an apparatus similar to a piezometer, but also accounting for fluid velocity). When plotted in profile, this ,parameter, is often referred to as the energy grade line, or EGL. For a lake or reservoir in which the velocity is essentially zero, the EGL is equal to the HGL.
