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...

The Nova Scotia Automated Surface Water Quality Monitoring Network was established in 2002 to assess water quality in surface waters across the province at five stations (and one discontinued station, St Mary's River).  The results are used to help manage water resources, determine baseline water...

In 2005, the Province of Ontario implemented its Ecological Framework for Recreational Fisheries Management, a component of which was the establishment of standardized, long-term monitoring of the province’s fisheries resource, referred to as Broadscale Monitoring. The Broadscale Monitoring...

Water chemistry data with geographic coordinates from lakes primarily in the Sudbury area of Ontario since 1981. Several lakes spread throughout the Sudbury acid rain damage zone had a natural buffering capacity protecting them from experiencing a severe drop in lake pH. Twenty-two of these lakes...

In 2017, the Ministry of Environment, Conservation, and Parks collected water and sediment from the Jackfish Bay ‘Area of Concern in Recovery’ study area, which included Moberley Bay, Tunnel Bay, and far-field sites in Jackfish Bay. This ‘Area of Concern in Recovery’ has been designated under...

This dataset includes information on biological communities in lakes and streams across Ontario since 1976. Biological communities sampled include: * crayfish Data were collected as part of routine monitoring of water quality of inland waters and for scientific and research purposes.

This dataset includes the following information for public registered and municipal drinking water supplies: Site Name, County, Date Boil Advisory Issued, Date Boil Advisory Removed, Facility Type (Registered or Municipal), Length of Advisory in Days, Reason for the Report. This dataset includes...

The Nova Scotia Automated Surface Water Quality Monitoring Network was established in 2002 to assess water quality in surface waters across the province at five stations. In 2019 the station list was modified to reduce overlap with Environment and Climate Change Canada surface water quality...

The B.C. copper water quality guideline (WQG) for the protection of aquatic life was updated in 2019 and now uses a biotic ligand model (BLM) to account for site specific toxicity modifying factors such as pH, dissolved organic carbon (DOC) and hardness. The B.C. copper BLM software, available on...

Height of Gauge (Stage): The height of the water above a set reference level measured in metres (m). The river stage is related to discharge but not equivalent and more information (i.e. a ratings curve) is required to calculate discharge from river stage. Discharge: The amount of water flowing...
