Secchi depth data and discrete depth profiles of water temperature, dissolved oxygen, conductivity, specific conductance, photosynthetic active radiation, redox potential, and pH for Beaverdam Reservoir, Carvins Cove Reservoir, Falling Creek Reservoir, Gatewood Reservoir, and Spring Hollow Reservoir in southwestern Virginia, USA 2013-2022

Discrete depth profiles of temperature, dissolved oxygen, oxidation-reduction potential, conductivity, specific conductance, and pH were collected with various handheld YSI water quality probes and discrete depth profiles of photosynthetic active radiation (PAR) were collected with a LI-COR underwater light meter from 2013 to 2022 in five drinking water reservoirs in southwestern Virginia, USA. Secchi disk depth data complement the PAR data to estimate water transparency. All YSI and PAR depth profiles were collected on approximately 1-meter intervals. 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 data package consists of two datasets: 1) YSI and PAR profiles; and 2) Secchi depth data. The YSI and PAR depth profiles and Secchi depths were measured at the deepest site of each reservoir adjacent to the dam and other in-reservoir transects. YSI measurements were also collected at a gauged weir on the primary inflow tributary at Falling Creek, other inflows and outflows at Falling Creek, inflows and outflows at Beaverdam, and inflows at Carvins Cove. In 2021, YSI profiles were also collected from a littoral site in Beaverdam. Data were collected approximately fortnightly in the spring months (March - May), weekly in the summer and early autumn (June - September), and monthly in the late autumn and winter (October - February) in Falling Creek and Beaverdam Reservoirs; data coverage in the other three reservoirs varies among years.2013年至2022年间，美国弗吉尼亚州西南部的五座饮用水水库中，采用多款手持式YSI水质探头采集了温度、溶解氧、氧化还原电位、电导率、比电导率及pH值的离散深度剖面数据；同时使用LI-COR水下光计采集了光合有效辐射（Photosynthetic Active Radiation, PAR）的离散深度剖面数据。赛氏盘（Secchi disk）深度数据可辅助PAR数据估算水体透明度。所有YSI及PAR深度剖面均以约1米的间隔进行采集。 本次研究涉及的五座水库分别为：弗吉尼亚州文顿市的Beaverdam水库、弗吉尼亚州罗阿诺克市的Carvins Cove水库、弗吉尼亚州文顿市的Falling Creek水库、弗吉尼亚州普拉斯基县的Gatewood水库，以及弗吉尼亚州塞勒姆市的Spring Hollow水库。其中Beaverdam、Carvins Cove、Falling Creek及Spring Hollow水库由西弗吉尼亚州水务管理局（Western Virginia Water Authority）所有并运营，作为弗吉尼亚州罗阿诺克市的一级或二级饮用水源；Gatewood水库则为弗吉尼亚州普拉斯基镇的饮用水源。 本数据包包含两类数据集：1）YSI与PAR深度剖面数据；2）赛氏盘深度数据。YSI、PAR深度剖面及赛氏盘深度数据均采集于各水库紧邻大坝的最深点位，以及水库内部的其他样线。此外，研究团队还在Falling Creek水库主要入流支流的计量堰、Falling Creek的其余入流与出流点位、Beaverdam水库的入流与出流点位，以及Carvins Cove水库的入流点位采集了YSI测量数据。2021年，研究团队还在Beaverdam水库的沿岸带点位采集了YSI剖面数据。 针对Falling Creek与Beaverdam水库，数据采集频率设置为：春季（3月至5月）约每两周一次，夏季与初秋（6月至9月）每周一次，晚秋与冬季（10月至次年2月）每月一次；其余三座水库的数据覆盖范围随年份存在差异。
