Water level and discharge data are available from Water Survey of Canada’s Hydrometric Network. The Water Survey of Canada (WSC) is the national authority responsible for the collection, interpretation and dissemination of standardized water resource data and information in Canada. In partnership with the provinces, territories and other agencies, WSC operates over 2500 active hydrometric gauges across the country, maintains an archive of historical information for over 7600 stations and provides access to near real-time (water level and stream flow) provisional data at over 1700 locations in Canada. Monitoring activities are underway to collect suspended sediment samples in the Lower Athabasca River.

This site provides public access to real-time hydrometric data collected at over 1800 locations and access to historical data collected at over 7600 stations (active and discontinued) in Canada.

Hydrometric data are collected and compiled by Water Survey of Canada’s eight regional offices and housed in two centrally-managed databases: HYDEX and HYDAT.

Historical hydrometric data are standardized water resource data and information. They are collected, interpreted and disseminated by the Water Survey of Canada (WSC) in partnership with the provinces, territories and other agencies through the National Hydrometric Program. These data sets include daily mean, monthly mean, annual maximum and minimum daily mean and instantaneous peak water level and discharge information for over 2700 active and 5080 discontinued hydrometric monitoring stations across Canada.

This site provides public access to real-time hydrometric data collected at over 1800 locations and access to historical data collected at over 7600 stations (active and discontinued) in Canada. These data are collected under a national program jointly administered under federal-provincial and federal-territorial cost-sharing agreements. It is through partnerships that the Water Survey of Canada program has built a standardized and credible environmental information base for Canada.

In partnership with the provinces, territories and other agencies, the Water Survey of Canada (WSC) operates a network of over 2600 active hydrometric gauges across the country. This dataset consists of a set of polygons that represent the drainage areas of active discharge stations across Canada. The NHS Basin Polygon dataset is compilation of datasets collected from a number of contributing agencies, including provinces, territories and other government departments. Environment and Climate Change Canada staff in a number of offices across the country is also responsible for the derivation of large parts of the dataset.

1. Provides public access to real-time instantatenous water level collected at over 1800 active locations in Canada. These data are collected under a national program jointly administered under federal-provincial and federal-territorial cost-sharing agreements; 2. Provides public access to archived daily water level for stations of interest using search criteria.

The surface water quality (WQ) program, as part of the Joint Canada/Alberta Implementation Plan, is designed to improve the ability to detect change and predict effects in relation to point and non‐point sources. A mass‐balance approach has been used for assessing the quantity, movement, and cycling of materials in the watershed. Applying this approach required a sampling program which included quantification of the sources, transport, flux, and fate of materials and contaminants. The Surface WQ monitoring sampling includes, in part, collection of;

• event (freshet and rain) based WQ samples in tributaries ranging from daily to bi-weekly,

• WQ samples in the Athabasca River using cross-channel transect methods at specified Phase 1 sites,

• enhanced (additional parameters) WQ sampling at M9, M12, and M11A and at 5 new interconnecting channel stations within the Expanded Geographical Area (EGA),

• ground water samples in specific high priority tributaries, and

• auto-monitoring (near real-time) on a subset of parameters at sites in the EGA

The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The Water quantity in Canadian rivers indicators provide information about the state of the amount of surface water in Canada and its change through time to support water resource management. They are used to provide information about the state and trends in water quantity in Canada. Information is provided to Canadians in a number of formats including: static and interactive maps, charts and graphs, HTML and CSV data tables and downloadable reports.

This dataset consists of a set of polygons that represent the drainage areas of active discharge stations within the Maritime Province Drainage Area.
