Now called the Campus Dam

Work on the Upper SLO Dam began on January 5th 2016. The goal of this project is to provide a 48 Acre-Foot detention basin to reduce the peak flow from 1480 Cubic Feet per Second (CFS) down to approximately 510 CFS, which will be discharged in a controlled fashion, greatly increasing downstream safety of the CNM campus and downstream properties. This facility will be the first facility constructed on the Barranca Arroyo and will help increase storm water quality by removal of debris and floatables from storm flows originating in the upper basin. The reduced outflow from this project will remain in the traditional arroyo channel which bisects the CNM Rio Rancho campus. SSCAFCA is currently working with CNM to maintain this arroyo in a natural state and incorporate it into an outdoor classroom educational area. The construction will only include hardened elements at the inlet and outlet, the remainder of the site will be maintained in a natural state to conserve the maximum amount of habitat. The arroyo system with the CNM campus will be developed into a living classroom to allow students to observe the physical and environmental characteristics of a natural arroyo system.

On March 1st the Upper SLO Dam was re-named to Campus Dam. The project is 50% complete with the outlet concrete box culvert(CBC) floor and Energy Dissipater floor constructed. In the next two weeks: continued earthwork and grading activities, outlet concrete box culverts placement and the form footing for the inlet structure retaining walls will begin.



For the week of March 21st:

Activities planned the next 2 weeks: Inlet retaining walls and principal spillway structural concrete placement, begin backfilling all footings, and construction of dam embankment. Since the last update: the concrete box culvert is completed, energy dissipater is constructed and the project is at 53% completion and on schedule.
