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...

In 2022, the Watershed Hydrology and Ecosystems Research Division of Environment and Climate Change Canada (ECCC) uploaded a Lake Ice Database to the Government of Canada open data portal (https://data-donnees.ec.gc.ca/data/water/scientificknowledge/lake-ice-database/?lang=en). This companion...

Water quality and ecosystem health data used to conduct a cumulative effects assessment of Lake Huron and St. Marys River nearshore waters in support of the Great Lakes Water Quality Agreement are included in this dataset. Data related to nearshore stressors is integrated into an overall...

National Water Monitoring Program for Pesticides (NWMPP) water quality data are presented for a network of freshwater sites across Canada. A two-year pilot program is being conducted in partnership between Health Canada (HC), Environment and Climate Change Canada (ECCC), and Agriculture and...

Weekly precipitation quantity has been measured at both at the primary meteorological site as well as at five other sites within the watershed. Daily precipitation quantity has been measured at the primary meteorological site until 2017. Weekly chemistry analysis of H+, major ions, nutrients and...

Increased flux of carbon and nutrients from human activities in river basins were linked to acidification and deepwater hypoxia in estuaries and coastal areas worldwide. Annual loads (1995–2011) of suspended particulate matter (SPM), dissolved organic carbon (DOC), total nitrogen (TN) and total...

Continuous, year-round measurement of stream stage that is later converted to flow using a stage-discharge relationship occurs on at/near the lake outflows and 2 other stations along the principal watershed tributary, Norberg Creek. Measurements ended in 2016. Supplemental Information The Climate...

The Turkey Lakes Watershed (TLW) is 1 of 5 hydrologically "calibrated" basins in eastern Canada that were originally devoted to process-oriented research into "acid rain" effects. They were selected to cover a wide range of climatic and hydrological conditions, deposition magnitudes, and terrain...

Groundwater wells were installed in the Turkey Lakes Watershed basin in the early 1980’s. These test wells were installed in eight sub-basins of the watershed and range in depth from 0.5 to 9.7 metres. They are located on a variety of terrain throughout. The water chemistry has been sampled at...

One component of this initiative aims to improve current understanding of nutrient dynamics and cyanobacterial and harmful bloom (cHAB) occurrences on Lake of the Woods. Research will focus on investigating the sources of nutrients and additional mechanisms influencing cHAB development and...
