Time series of high-frequency profiles of depth, temperature, dissolved oxygen, conductivity, specific conductivity, chlorophyll a, turbidity, pH, and oxidation-reduction potential for Beaverdam Reservoir, Carvins Cove Reservoir, Falling Creek Reservoir, Gatewood Reservoir, and Spring Hollow Reserv

Depth profiles of depth, temperature, dissolved oxygen, conductivity,
specific conductivity, chlorophyll a, turbidity were collected with a
CTD (Conductivity, Temperature, and Depth) profiler fitted with a SBE
43 Dissolved Oxygen sensor and an ECO Triplet Fluorometer and
Backscattering Sensor from 2013 to 2017. In 2017, pH and
oxidation-reduction potential (ORP) were also collected with a SBE 27
pH and O.R.P. (redox) sensor. CTD profiles were collected in five
drinking water reservoirs in southwestern Virginia, USA. All variables
are measured every 0.25 seconds, resulting in depth profiles at
approximately ten centimeter resolution. The five 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 CTD depth profiles
measured at the deepest site of each reservoir adjacent to the dam as
well as other reservoir sites on a transect upstream in Carvins Cove
Reservoir and Falling Creek Reservoir. The profiles were collected
approximately fortnightly in the spring months, weekly in the summer
and early autumn, and monthly in the late autumn and winter.
