Abstract:

Depth profiles of water biogeochemical properties were collected with SeaBird Electronics (SBE) Conductivity, Temperature, and Depth (CTD) profilers from 2013-2023. Data availability differs across years due to additional sensors that have been added over time. From 2013-2016 profiles were taken with a CTD equipped with an SBE 43 Dissolved Oxygen sensor and an ECO FLNTU sensor for turbidity and chlorophyll. From 2017-2023, profiles were taken with a CTD equipped with an SBE 43 Dissolved Oxygen sensor, an ECO FLNTU sensor for turbidity and chlorophyll, a PAR-LOG ICSW sensor for photosynthetically active radiation, and a SBE 27 pH and ORP (oxidation-reduction potential) sensor. In 2022 and 2023, profiles were also taken with an additional CTD equipped with an SBE 43 Dissolved Oxygen sensor, an ECO Triplet Scattering Fluorescence sensor for CDOM, phycocyanin, and phycoerythrin, an ECO FLNTU sensor for turbidity and chlorophyll, and PAR-LOG ICSW for photosynthetically active radiation. 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 upstream reservoir sites. 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 (2013-2023); Spring Hollow Reservoir was only sampled 2013-2017 and 2019; 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 2023 using a Conductivity, Temperature and Depth (CTD) profiler from SeaBird Electronics (SBE, Bellevue Washington, USA) at five reservoirs. Beaverdam Reservoir, Carvins Cove Reservoir, and Falling Creek Reservoir were sampled every year in the dataset (2013-2023); Spring Hollow Reservoir was only sampled 2013-2017 and 2019; and Gatewood Reservoir was only sampled in 2016. Within their sampling duration, profiles were collected, at minimum, monthly between May to October (usually weekly or subweekly at Beaverdam Reservoir and Falling Creek Reservoir), 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 2018–2023, and are denoted with a negative depth measurement that indicates the distance above the surface of the reservoir.

The CTD was calibrated by the manufacturer according to the standards and practices of SBE and the companies with secondary sensors coupled to the instrument. Calibration was performed yearly (usually in December-February), except during/before the 2021 field season when calibration was delayed until August 2021 due to the ongoing COVID-19 pandemic.

Flags indicate known or suspected issues with measured variables. We note that the Depth_m likely also includes marginal error over the course of the dataset, but this error is unquantified and unflagged. Due to the challenges of measuring pH, ORP, and turbidity in situ, we recommend caution in interpreting these data.

INSTRUMENTS, MANUAL, AND SERIAL NUMBERS USED BETWEEN 2013 - 2022

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.

Contributions to the 2023 revision:

CCC developed and led the reservoir monitoring program 2013-present, and oversaw CTD purchasing, use, and maintenance throughout this time. ASL developed the QAQC script, visual inspection script, and maintenance log in 2023. ABP led the field crew, contributed substantially to fieldwork, maintained the instrument, and processed data in 2023.

Acknowledgments and historical contributions:

This data package has been iteratively updated over time and builds on the many historical contributions of co-authors listed in previous revisions. We thank the Western Virginia Water Authority for providing access to these sites and the Reservoir Group for contributing to fieldwork; Austin Delany for assisting with the development and maintenance of workflows and QAQC; and to Kathryn Hoffman, Mary Lofton, and Freya Olsson for constructive reviews.
