Home » Shop » 2006 – Design and Construction of the Ridges Basin Dam
Ridges Basin Dam is part of the Animas-La Plata Project. When topped out in approximately 2008, it will be Reclamation’s newest dam. It will have a structural height of 273 feet and impound 120,000 acre-feet of water. This paper will discuss the design of the embankment and will detail the site geology, the general design considerations for layout and zoning, and other technical considerations. The construction, which began in 2004, is ongoing. This paper will also discuss foundation treatment and cleanup, the placement of the embankment material, grouting, and the unusual material processing for filters and drains, along with general construction details. Also included in the paper are the challenging arrangements for contracting by the American Indian Self Determination and Education Assistance Law, an overview of the dam safety risk analyses conducted on the yet-to-be-constructed embankment, and modern construction techniques being utilized to build the embankment.
