The Water Survey of Canada (WSC) is a scientific branch of Environment and Climate Change Canada, responsible for monitoring the nation's freshwater resources. The WSC maintains Canada's hydrometric data network, widely referred to as HYDAT. Previously over 2,500 hydrometric gauges were maintained.
Great Lakes’ water levels have shown substantial variability during the 20th century with no evidence of a long-term trend. Lower levels coincided with the droughts of the 1930s, early 1960s, and the recent 1999-2001 dry period. Over the Prairies, the numbers and water levels of wetlands have shown no clear trend over the last 40 to 50 years.
Temporarily shifted rating curve for station 05CK004, Red Deer River near Bindloss, Alberta, Canada, operated by Water Survey of Canada. Canadian streams and rivers are monitored by the Water Survey of Canada, a branch of Environment and Climate Change Canada. As of 2021, it operates or collects data from more than 2800 gauges across Canada. [6]
[1] Water pollution in Canada is caused by municipal sewage, urban runoff, industrial pollution and industrial waste, agricultural pollution, inadequate water infrastructure. This is a long-term threat in Canada due to "population growth, economic development, climate change, and scarce fresh water supplies in certain parts of the country." [2]
Environment and Climate Change Canada is the federal department in charge of conserving and protecting Canada's water resources. The Water Act (2000), a federal legislation, "supports and promotes the conservation and management of water, including the wise allocation and use of water.".
Most water in Earth's atmosphere and crust comes from saline seawater, while fresh water accounts for nearly 1% of the total. The vast bulk of the water on Earth is saline or salt water, with an average salinity of 35‰ (or 3.5%, roughly equivalent to 34 grams of salts in 1 kg of seawater), though this varies slightly according to the amount of runoff received from surrounding land.
This new ecozone map includes 18 terrestrial, 12 marine and 1 freshwater ecozone, the latter two of which were derived from the marine bioregions outlined by Fisheries and Oceans Canada in 2009. [8] [6] This comprehensive framework is currently in use by Environment and Climate Change Canada to determine protected area coverage of Canada's ...
Among countries that emit high levels of greenhouse gas, Canada is among the highest per person emitters. [1] CO 2 emissions in Canada, 1785-2022. Climate change is greatly impacting Canada's environment and landscapes. Extreme weather has become more frequent and severe because of the continued release of greenhouse gases into the atmosphere.
