La Romaine Hydroelectric Complex water chemistry from 2015 to 2023 [Quebec, Canada]

Data were collected from 2015 to 2023 across the four reservoirs of La Romaine Hydroelectric Complex. The four reservoirs are Romaine-1 (RO1), Romaine-2 (RO2), Romaine-3 (RO3), and Romaine-4 (RO4). Samples consist of concentrations of total nitrogen (TN in mg/L), total phosphorus (TP, in ug/L), dissolved organic carbon (DOC, in mg/L), dissolved inorganic carbon (DIC, in mg/L), particulate organic carbon (POC, in mg/L), particulate organic nitrogen (PON in mg/L), chlorophyl (Chl-a, in mg/L), and C13 isotopes of POC (in permil dirac delta), and total suspended solids (TSS, in mg/L). The data set also include the samples type (river, reservoirs, tributary) and if it is a hyporheic sample), latitude and longitude, and river distance (km) for each sample.
Sampling consisted of spatial across all the reservoirs (open water and bays) and longitudinal coverage of the reservoirs and river (above and below each reservoir) for each sampling camping (June and August 2015; June, August, and October 2016;
June, August, and October 2017; June, August, and October 2018; June, August, and October 2021; June, August, and October 2022; June, August, and October 2023). All samples are surface water samples unless otherwise indicated in the sample type column.

Included are also monthly average of input and output discharge from each reservoir from 2015 to 2023 and daily average of La Romaine River above the upmost reservoir.

La Romaine Hydroelectric Complex is located in northeastern Quebec and accessed from Havre-Saint-Pierre, Quebec, Canada.
