Water chemistry time series for Beaverdam Reservoir, Carvins Cove Reservoir, Falling Creek Reservoir, Gatewood Reservoir, and Spring Hollow Reservoir in southwestern Virginia, USA 2013-2018

Depth profiles of dissolved organic carbon and total and dissolved
nitrogen and phosphorus were sampled from 2013 to 2018 in five
drinking water reservoirs in southwestern Virginia, USA. These
reservoirs are: Beaverdam Reservoir (Vinton, Virginia), Carvins Cove
Reservoir (Roanoke, Virginia), Falling Creek Reservoir (Vinton,
Virginia), Gatewood Reservoir (Pulaski, Virginia), and Spring Hollow
Reservoir (Salem, Virginia). Beaverdam, Carvins Cove, Falling Creek,
and Spring Hollow Reservoirs are owned and operated by the Western
Virginia Water Authority as primary or secondary drinking water
sources for Roanoke, Virginia, and Gatewood Reservoir is a drinking
water source for the Town of Pulaski, Virginia. The dataset consists
of depth profiles of water chemistry samples measured at the deepest
site of each reservoir adjacent to the dam. Additional water chemistry
samples were collected at a gauged weir on Falling Creek Reservoir’s
primary inflow tributary. The samples were collected approximately
fortnightly from March-April, weekly from May-October, and monthly
from November-February at Falling Creek Reservoir and Beaverdam
Reservoir, approximately fortnightly from May-August in most years at
Carvins Cover Reservoir, and approximately fortnightly from 2014-2016
in Gatewood and Spring Hollow Reservoirs. Depth profiles of dissolved
inorganic carbon were also collected in 2018, but the analytical
method for this analyte is still in development and these should be
considered as preliminary data only.
