What does the region's drought status mean to you?

Carvins Cove Sept 2015

While the geographic service areas of the Western Virginia Water Authority (Authority) are included in a moderate drought as designated by the United States Drought Monitor, the Authority does not need to issue voluntary or mandatory conservation measures at this time .


How is the Western Virginia Water Authority  responding to this moderate drought designation?

The Western Virginia Water Authority always encourages our customers to use water wisely and closely monitors water levels in the reservoirs.  The Carvins Cove and Spring Hollow reservoirs are above normal levels for this time of year and have an adequate water supply for more than 12 months.

One of the benefits the Water Authority offers customers is multiple sources of water.  Instead of having to rely on one source of water or a river that is quickly impacted by drought conditions, the Authority can balance the drinking water needs of customers across five surface water sources of water, a large groundwater source and multiple wells.


What are the levels of the reservoirs?  Is this normal for this time of year?

Current reservoir levels are updated daily and historic reservoir levels are listed on our reservoir level page.  Because of last year's wet weather, the reservoirs are storing more water than we typically see this time of year. Historically during the months of September/October, Carvins Cove has averaged 2.27-feet  to 6.87-feet below full pond.  Spring Hollow Reservoir is also above the level typically seen in the fall.


When would the Water Authority ask customers to conserve water?

The Authority's Drought Contingency Plan is based off levels in the Carvins Cove Reservoir during particular times of year.  This plan takes into account the historic fluctuations of water levels over the year.

Based on our drought contingency plan, the Authority would reach a "voluntary conservation" action level if the Carvins Cove reservoir level was to drop to about 20-feet below the spillway during the fall months. One of the reasons we have multiple reservoirs and groundwater sources is to minimize the impacts of moderate droughts.

For now, use water wisely.  The Western Virginia Water Authority will continue to monitor reservoir levels and demand and keep our customers informed of any changes.
