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...

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 data set includes information on water quality of lakes and streams across Ontario since 1976. It includes: * major anions and cations * nutrients * chlorophyll * metals Data were collected as part of routine monitoring of water quality of inland waters and for scientific and research purposes.

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.

Dataset includes 8 water quality surveys conducted between May and September 2021 at 4 stations in Hamilton Harbour by the Ontario Ministry of the Environment, Conservation and Parks (MECP) staff. The 4 stations surveyed by MECP are Environment and Climate Change Canada’s 4 long-term monitoring...

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...

The Department of Government Services and the Department of Health and Community Services are jointly responsible for monitoring the bacteriological quality of public water supplies in the province. This sampling activity is carried out on a regular basis by Environmental Health Officers located...
