Deere & Ault Consultants, Inc. has teamed with RJH Consultants to provide geotechnical engineering and dam design engineering services for a new large water storage reservoir near Holly, Colorado. The engineering work is being completed for Tri-State Generation and Transmission Association, Inc.
The dam and reservoir will store water for a new power generation facility planned for construction near Holly, Colorado. As presently conceived, the 135-foot high dam will impound a reservoir with a storage capacity of approximately 70,000 acre-feet.
The project has relatively complex geology and challenging foundation conditions. Site investigations began in August 2009 in order to meet the client’s tight schedule. During the winter of 2009 – 2010, Deere & Ault and RJH performed a site screening study for the project.
In the spring of 2010, Deere & Ault opened a test quarry and performed a suitability evaluation of the limestone for use as riprap, concrete aggregate, and power plant emission stack scrubbers. In the fall of 2010, Deere & Ault performed additional site investigations for an alternate dam site.
Deere & Ault provided all engineering geologic and geotechnical engineering services for the dam and reservoir investigation, analysis, and design.
