With support from various other organizations, the Tusket River Environmental Protection Association collected an extensive water quality data base from numerous lakes in and near the Tusket catchment. Data were collected in early May, late August, and late October. Oxygen, conductivity, pH, and temperature profiles are available from 2012 to 2015. Subsequently, volunteers took the lead, but data on nutrients, colour, chlorophyll-a, pH and related data remain available. Investigations related to MTRI’s study on vulnerable shoreline Atlantic Coastal Plains Flora and NS Environment’s investigations into waters affected by effluent from mink farms. Support was provided by Mersey-Tobeatic Research Institute, N.S. Environment, Adopt-a-Stream, CURA H2O, and the Municipalities of Yarmouth and Argyle.
