Low Head Dam Design & Survey

DGR performed the topographic survey as well as the design of the low head dam.  Construction of the dam involved removing an existing dysfunctional dam and installing sheet piles and rip rap.  After construction, the water table rose, benefiting the City’s well fields, and the water quality improved downstream.
