The top or crest of the dam should be a minimum of 10 feet wide (preferably 15 feet) to accommodate road traffic and minimize the potential for erosion. The crest elevation should be a minimum of three feet above the Full Supply Level (FSL) of the reservoir.
The key trench is incorporated in the design for two reasons: to anchor the dam to the base material and to prevent piping (seepage under the fill). The key trench should be a minimum of three feet deep for a dam the height of 10 to 12 feet. It should extend the full length of the dam and reach one third to one half of the way up the side slope of the draw. The dam must be constructed from an impervious (clay or clay-based) material.
