The Acid Sensitive Lakes Study in the Atlantic Canada was initiated in 1983 by Environment and Climate Change Canada, to evaluate the impact of acid atmospheric pollutant on aquatic ecosystem. Originally, the study focused on the aquatic and terrestrial effects of acid precipitation, but now it...

Provides stream water quality monitoring data for a number of parameters, including total and dissolved nutrients, metals, and chloride. The Provincial (Stream) Water Quality Monitoring Network (PWQMN) measures water quality in rivers and streams across Ontario. This dataset provides stream water...

Get data about the water quality for Ontario's inland lakes. The data is collected through volunteer monitoring efforts – citizen science. The Lake Partner environment map The Lake Partner Program (LPP) measures water quality in inland lakes across Ontario. This dataset provides water quality and...

This dataset is a simplified version of water quality measurements taken in Aulavik National Park. It is a collection of measurements which make up two water quality indexes: Nutrients and Major Ions (NMI) Index and Metals Index. The measurements are taken along the Thompson River annually in...

This dataset contains monitoring data for benthic invertebrate communities along the Thompson River Corridor. The raw data in this dataset is used to calculate benthic invertebrate richness and the percentage of Ephemeroptera (mayflies), Plecoptera (stoneflies), and Trichoptera (caddisflies)...

This dataset is a collection of measurements which make up two water quality indexes: Nutrients, Physical and Major Ions (NPMI) Index and Metals Index. The measurements are taken at two different locations along the Thompson River annually in early-July. The chemical composition of water...
