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 nitrate concentrations measured in Lake Santo Parmense in 1991. 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. Samples were analysed by means of the Sodium Salicylate Method (Rodier, 1978).

Dataset provides dissolved oxygen measured in Lake Santo Parmense during the period 2001-2003. 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. Dissolved oxygen was measured by means of the Winkler method.
