This document provides an overview of the construction and design process for earthen dams. It discusses site identification and preparation, including clearing, grubbing, and stripping the area. The main construction steps described are diverting the stream, preparing the foundation, excavating borrow pits, placing and compacting fill, and installing drainage systems. Design considerations include providing adequate spillway capacity, stable slopes, an impervious core, and downstream drainage. Common materials used include gravel, sand, clay and filters. Machinery used for excavation, hauling, and compaction is also outlined. Quality control measures like drainage, moisture control, and compaction in layers are recommended.
