Location map of the Itupararanga Reservoir. Sampling sites P1 to P7 were sampled between December 2016 and December 2018 and are indicated by red stars. The reservoir boundaries were outlined using RapidEye images (5-m spatial resolution from 17 July and 30 August 2014) provided by Ministry of Environment and their drainage systems (1: 25.000) were downloaded from DataGeo (https://datageo.ambiente.sp.gov.br/app/#). All data processing operations were carried out using the software ArcGis 10.2.2 (ESRI, USA) and the maps were projected onto a common coordinate system (World Geodetic System 1984 [WGS 84]).
