The Chimney Hollow Reservoir Project (CHRP) is located southwest of Loveland, Colorado.
CHRP is a component of the Windy Gap Firming Project, operated by the Municipal Subdistrict of the Northern
Colorado Water Conservancy District. The inlet/outlet tunnel (IOT) for CHRP contains a reinforced concrete
lined alve Chamber with PC membrane waterproong that was ecavated via seuential ecavation method
to a diameter of feet. The IOT was ecavated using both drill and blast and road header with ground support
consisting of steel sets, rock bolts, wire mesh and shotcrete. The IOT will withstand 300 feet of water head and
rock ll surcharge load from the dam embankment constructed over the tunnel.
