Dataset provides ammonia concentrations measured in Lake Santo Parmense during the period 1953-1954. Water samples were collected by means of a Ruttner bottle only from the surface layer at the point of maximum depth of the lake. No information on the analytical method used is available.

Dataset provides water transparency measured by means of a Secchi disk in Lake Santo Parmense in 1991.

Dataset provides pH measured in Lake Santo Parmense during the period 2007-2010. Water samples were collected by means of a Ruttner bottle at different depths over the whole water column at the point of maximum depth of the lake. pH was measured by means of a pH meter.

The dataset contains records of Fishes (Pisces) collected in the lower valley of River Sabor (NE Portugal) in the scope of the long-term Ecological Monitoring Program (PME) of the Baixo Sabor Hydroelectric Dams (AHBS), promoted by EDP – Energias de Portugal, S.A, to evaluate the impacts of dam construction in the fish communities and water quality of the river. This dataset refers to the year of 2012, during the construction process. Fishes were captured in 16 sampling stations by electrofishing (with restitution) in speing and autumn of 2012. A total of 2214 records of 11 species and one genus were obtained.

The dataset contains records of Phytobenthos collected in the lower valley of River Sabor (NE Portugal) in the scope of the long-term Ecological Monitoring Program (PME) of the Baixo Sabor Hydroelectric Dams (AHBS), promoted by EDP – Energias de Portugal, S.A. Data were collected in May 2012, during field visits to 23 sampling stations located along the lower Sabor valley up to 70 km upstream of the mouth, and in the Vilariça stream. A total of 9552 individuals belonging to 78 species and other taxonomic categories were found and identified.
