Secchi depth data and discrete depth profiles of photosynthetically active radiation, temperature, dissolved oxygen, and pH for Beaverdam Reservoir, Carvins Cove Reservoir, Falling Creek Reservoir, Gatewood Reservoir, and Spring Hollow Reservoir in southwestern Virginia, USA 2013-2017

Discrete depth profiles of temperature, dissolved oxygen, and pH were
collected with a YSI water quality probe and discrete depth profiles
of photosynthetically active radiation (PAR) were collected with a
LI-COR underwater light meter from 2013 to 2017 in five drinking water
reservoirs in southwestern Virginia, USA. Secchi disk depth data
complement the PAR data to estimate water transparency. Additional
variables measured by the YSI are conductivity and ORP (oxidation
reduction potential or redox); 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; 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 (Site 50), as well as at a gauged weir
on the primary inflow tributary (Site 100) at Falling Creek Reservoir
and other in-reservoir transects in Falling Creek Reservoir (Site 45,
30, 20, 10). The samples were collected approximately fortnightly in
the spring months (Mar. - May), weekly in the summer and early autumn
(Jun. - Sept.), and monthly in the late autumn and winter (Oct. -
Feb.).
