Approximate centerline location of major energy transmission pipelines including the name of each pipeline.

Data from the RUISSO program, bacteriological and physicochemical quality of streams and inland water bodies in the Montreal agglomeration, from the Aquatic Environment Monitoring Network. An [interactive map] (https://experience.arcgis.com/experience/38d7c7bb43da4e2082aa836689d0d318/) is also...

This theme presents the trophic status of lakes monitored as part of the Voluntary Lake Monitoring Network (RSVL) between 2004 and 2020. The trophic state is the result of the compilation of data acquired as part of this network. Trophic levels are used to classify lakes according to their degree...

Note that topographic maps at a scale of 1/100,000 are no longer updated. For the latest update date, see the [metadata] (ftp://transfert.mern.gouv.qc.ca/public/diffusion/RGQ/Documentation/BDAT/Metadonnees_BDAT100k_NordSud.xls). The reference cartographic data is now constituted according to a...

This dataset represents lithogeochemistry of Saskatchewan samples. This dataset represents lithogeochemistry of Saskatchewan samples. This dataset represents the exhaustive mapping and sampling program of the Athabasca Group between 1975 and 1981 by the Saskatchewan Geological Survey (SGS), the...

Water temperature and water level are significant environmental factors affecting ecology of anadromous fish. Large-scale freshwater monitoring networks remain sparse, yet environmental protocols rely heavily on water temperature and water levels to assist decision making on river closures. Our...

This layer shows the location of the sampled stations classified according to the Eastern Canada Diatom Index (IDEC). It contains data obtained since 1935 that was converted to version 3 of the index (Lavoie et al. 2014). Benthic diatoms are microscopic unicellular algae that line the bottom of...

Municipalities with established populations of Ixodes scapularis ticks (blacklegged ticks) are municipalities where tick populations reproduce and survive from one year to the next. This indicator makes it possible to identify municipalities where their presence suggests a higher risk of tick...
