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.

Dataset provides monthly precipitation data collected at different weather stations that are closest to Lake Santo Parmense and Lake Scuro Parmense. We provide a long-term dataset (1951-2010) collected at two stations near the town of Bosco di Corniglio. In particular, from 1951 to 1998 precipitation data were collected at the weather station of Bosco Centrale. Between 1999 and july 2000 the station was out of order (no data available) and from 2001 the Bosco Centrale weather station was substituted by the Bosco di Corniglio station. The two weather stations are less than 1 km apart and they are about 6 km far from Lake Santo Parmense and 7 km far from Lake Scuro Parmense. We also provide a shorter dataset of precipitation data collected from 1994 to 2010 at the weather station of Lagdei. This station is closer to our sampling sites (about 1 km from Lake Santo Parmense and 5 km from Lake Scuro Parmense), but a shorter time series is available. All weather stations are managed by the the Environmental Protection Agency of the Emilia-Romagna region (ARPA Emilia-Romagna), which kindly provided data.

Dataset provides pH measured in Lake Santo Parmense during the period 1971-1974. 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.
