Abstract:	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 2020. From 2017-2020, 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 were measured every 0.25 seconds, resulting in depth profiles at approximately ten centimeter resolution. The five study 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. Beaverdam Reservoir, Carvins Cove Reservoir, and Falling Creek Reservoir were sampled every year in the dataset (2013-2020); Spring Hollow Reservoir was not in sampled in 2018 or 2020; and Gatewood Reservoir was only sampled in 2016.

Methods and protocols used in the collection of this data package

Description:

Depth profiles of multiple water-quality variables were collected from 2013 through 2020 using a Conductivity, Temperature and Depth (CTD) profiler from SeaBird Electronics (SBE, Bellevue Washington, USA). Profiles were collected, at minimum, monthly between May to October (usually weekly or subweekly), and bimonthly between November to April. Most CTD casts were collected from 9:00 to 15:00, however, some CTD casts were collected at night. Above water temperature and PAR are included in the dataset for 2018–2020, and are denoted with a negative depth measurement that indicate the distance above the surface of the reservoir.

The CTD was calibrated by the manufacturer yearly (usually in December-February) according to the standards and practices of SBE and the companies with secondary sensors coupled to the instrument.

INSTRUMENTS, MANUAL, AND SERIAL NUMBERS USED BETWEEN 2013 - 2020

Multiple sensors and instruments were added over time; below we note changes in the CTD software, sensor versions, and provide links to the accompanying instrument manuals.

Additional Info

Additional Information:

From 2013 to 2020, multiple whole-ecosystem manipulations were conducted at Falling Creek Reservoir. These manipulations include intermittent operation of hypolimnetic oxygenation and pulsed epilimnetic mixing engineering systems. For a detailed description of the hypolimnetic oxygenation engineered system, see Gerling et al. (2014) and for a detailed description of the epilimnetic mixing engineered system, see Chen et al. (2017). These systems were operated over time following Table 1 in Gerling et al. (2016), Table 1 in Munger et al. (2016), and Table 2 in McClure et al. (2018).
