The greatest advance in dam safety practice for earth dams is the implementation of engineered filters. Engineered filters, for all practical purposes, were not implemented in dam design until about the 1980s. Most dams constructed before this era likely do not meet modern filter design criteria to protect against internal erosion...."

Lowering the reservoir may be needed for temporary construction, for emergency response, or when regular releases aren't needed.

The key operational parameters are: (1) the required hydraulic lift cannot exceed the effective local atmospheric pressure adjusted for vapor pressure and frictional losses; (2) the..."
