Abstract
The South Fork Rivanna Reservoir (SFRR) is an instream reservoir furnishing a substantial portion of the raw water supply to the Charlottesville and Albemarle County, Virginia Urban Service area. The rapid rate of sedimentation of this reservoir is prompting water planners to search for ways to secure a reliable future water supply. Present water demand is expected to exceed the safe yield of the water supply system by the year 2002. By the year 2050, the forecasted demand of a projected population of 110,000 will be twice what existing facilities could supply during critical periods of drought. A key factor in this mismatch in water supply/demand is the steady loss of capacity in SFRR, which is losing usable storage at the rate of 1.4 % per year due to deposition of sediment on the bottom of the reservoir. The declining capacity of the reservoir due to sedimentation has long been recognized. For many years, Albemarle County has restricted residential and industrial development within the reservoir watershed so as to minimize runoff of sediment and other pollutants. At the same time, the County has worked in partnership with the Thomas Jefferson Soil & Water Conservation District and the Virginia Department of Forestry to promote agricultural and forestry practices within the watershed that minimize pollutant runoff. It is not clear to what
