Title:	Water chemistry time series for Beaverdam Reservoir, Carvins Cove Reservoir, Falling Creek Reservoir, Gatewood Reservoir, and Spring Hollow Reservoir in southwestern Virginia, USA 2013-2019
Alternate Identifier:	DOI PLACE HOLDER
Abstract:	Depth profiles of dissolved organic carbon and total and dissolved nitrogen and phosphorus were sampled from 2013 to 2020 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, as well as surface samples at multiple upstream and inflow sites in Falling Creek Reservoir and Beaverdam Reservoir in 2019 and 2020. The water column 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 Cove Reservoir, and approximately fortnightly from 2014-2016 in Gatewood and Spring Hollow Reservoirs, though sampling frequency and duration varied among reservoirs and years. Depth profiles of dissolved inorganic carbon were also collected from 2018-2020, but the analytical method for this analyte is still in development and these should be considered as preliminary data only.

Description:

SAMPLING TIMES Most sampling occurred between the hours of 9:00 and 15:00, and are denoted in the DateTime as 12:00. Some sampling occurred outside of these hours, including some overnight sampling; these instances are noted by the actual sampling time within the DateTime column. For more information about nighttime sampling, see Doubek et. al. 2018.

SAMPLE COLLECTION AND EQUIPMENT

Total nitrogen (TN) and total phosphorus (TP) Unfiltered water samples were collected at specified depths for each reservoir using a 4L Van Dorn water sampler (Wildco, Yulee, Florida, USA). Sample timestamps for samples collected between approximately 9 a.m. and 3 p.m. were standardized to noon. Samples collected for projects that required sample collection at specific times of day were standardized to the top of the hour during which they were collected (i.e., a sample timestamp of 16:00 indicates a sample taken between 4 and 5 p.m.). Samples were stored in acid-washed 125 mL polypropylene bottles and frozen within 12 hours. Samples were generally analyzed within one year of collection date. Soluble reactive phosphorus (SRP), nitrate (NO3), ammonium (NH4), dissolved organic carbon (DOC), dissolved inorganic carbon (DIC), and total dissolved nitrogen (DN) Water samples were collected at specified depths for each reservoir using a Van Dorn water sampler and were filtered with a 0.7 um glass fiber filter (Thomas Scientific GF/F) before being stored in acid-washed 125 mL polypropylene bottles. Sample timestamps for samples collected between approximately 9 a.m. and 3 p.m. were standardized to noon. Samples collected for projects that required sample collection at specific times of day were standardized to the top of the hour during which they were collected (i.e., a sample timestamp of 16:00 indicates a sample taken between 4 and 5 p.m.). Samples were frozen within 12 hours. Samples were generally analyzed within six months of collection date.

CHEMICAL ANALYSES AND EQUIPMENT

TN and TP Samples were digested with alkaline persulfate (Patton and Kryskalla 2003) and then analyzed colorimetrically using flow injection analysis (APHA 2005). TN was analyzed using the cadmium reduction method (APHA 1998) and TP was analyzed using the ascorbic acid method (Murphy and Riley 1962) on a Lachat Instruments XYZ Autosampler ASX 520 Series and QuikChem Series 8500 (Lachat ASX 520 Series, Lachat Instruments, Loveland, Colorado, USA).

SRP, NO3, NH4 Samples were analyzed colorimetrically using flow injection analysis (APHA 2005). SRP was analyzed using the ascorbic acid method (Murphy and Riley 1962), NO3 was analyzed using the cadmium reduction method (APHA 1998), and NH4 was analyzed using the Berthelot Reaction method (Solorzano 1969, APHA 2005) with a common modification as to the source of the hypochlorite ion as described in Zhang et al. 1997 on a Lachat Instruments XYZ Autosampler ASX 520 Series and QuikChem Series 8500 (Lachat ASX 520 Series, Lachat Instruments, Loveland, Colorado, USA).

DOC and DIC DOC was analyzed using the persulfate catalytic method (Brenton and Arnett 1993) on a TOCA 1010 from OI Analytical from 2013-2016 (OI Analytical 1010 Total Organic Carbon Analyzer with 1051 autosampler, College Station, TX USA) and on a Vario TOC Cube from Elementar from 2016-2017 (vario TOC cube, Elementar Analysensysteme GmbH, Hanau, Germany). Carbon in samples is oxidized to carbon dioxide (CO 2 ) either by reaction with acid or by catalyzed combustion at 850 C. Resulting carbon dioxide is detected by nondispersive infrared (NDIR) spectrometry.

DN Sample is combusted using the Vario TOC Cube from Elemantar at 850 degrees C. Total bound nitrogen in the combustion product is converted to nitrogen monoxide (NO) by oxidative pyrolysis then reacts with electrolyte in the electrochemical cell producing a measurable current to calculate total dissolved nitrogen (organic and inorganic together).

DATA FLAGS We note that measurements with multiple flags are coded as a multiple-digit number (e.g., a flag of '43' indicates there was 4 = negative value set to zero and 3 = sample below detection). No delimiter was added to separate flag codes in those columns. For data with a '74' flag, data was set to 0 before averaging as to not include the negative value in the final sample value.

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). In 2019, the HOx was activated during the following time periods: 29 June to 11 September, 25 September to 02 December. In 2020, the HOx was activated during the following time periods: 29 June to 11 September, 25 September to 02 December.
