The Sugar Hollow Reservoir is formed by the Sugar Hollow Dam, constructed in 1947 on the Moormans River to expand the public water supply system.
The reservoir is the highest of the RWSA's three, and as such is used to help fill the others. The Sugar Hollow Pipeline connects to the Ragged Mountain Reservoir, and reservoir overflow leads to the South Fork Rivanna Reservoir via river flow[1].
Landslide and 1999 expansion
An inflatable bladder was added to the spillway crest in 1999 to increase spillway capacity while maintaining original storage capacity. The normal pool elevation with the inflatable bladder raised position is 975 feet. At this normal pool condition, the existing reservoir storage is approximately 360 million gallons, based on a bathymetric survey performed in September 1995 following a landslide in the reservoir. The June 1995 landslide resulted from severe rainfall and approximately 70 million gallons of storage was lost.[1]
