Friday’s rainfall is having more of an affect than you might think, but not quite enough to get the water authority to pull back those water restrictions just yet.
If we get the forecasted one inch of rain, that could be enough rain to bring the South Fork Reservoir up by a foot. That’s because it’s not just the water that falls into the reservoir, but the water that trickles down in off the land that raises the levels.
But that's only one of three reservoirs feeding the area's water supply. The Rivanna Water and Sewer Authority says the Sugar Hallow Reservoir is the one we really need to watch.
“We need quite a bit of rain. It is down 13 feet, so we need several inches of rain to bring that back up,” said Tom Frederick, with the Rivanna Water and Sewer Authority.
And, until the Sugar Hallow Reservoir is within five feet of capacity, the drought warning will remain in affect.
The area's third reservoir, Ragged Mountain, is down about two feet. This rain fall is not expected to have much of an impact on that reservoir.
