Tire wear particles end up on roads where they may run off into nearby rivers and lakes by rain and snowmelt. This study examined how toxic these tire particles are to eggs and the newly hatched larvae of the fathead minnow (Pimephales promelas). Tire particles were finely ground up and were...

In 2006, the Government of Canada initiated the Chemicals Management Plan (CMP), which takes action regarding chemicals that are harmful to human health or the environment. One element of the CMP is Monitoring and Surveillance, which generates data on the presence and levels of chemical...

The purpose of this feature layer is to provide the 2011 overland flooding boundary in the Red River Valley. This dataset shows the extent of peak overland flooding in the Red River Valley in 2011. Data is based on RADARSAT – 1 satellite imagery. During processing, the raw data set was...

The purpose of this feature layer is to provide the 2009 overland flooding boundary in the Red River Valley. This dataset shows the extent of peak overland flooding in the Red River Valley in 20 09 . Data is based on RADARSAT – 1 satellite imagery. During processing, the raw data set was...

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...

Knowledge of the location of Earth’s surface water in time and space is critical to inform policy decisions on environment, wildlife, and human security. Dynamic surface water maps generally represent water occurrence, also referred to as inundation frequency, depicting the percentage of valid...

This study examined the toxicity of aged oil sands tailings waste, and it's affect on eight species of freshwater aquatic organisms: Pimephales promelas (fathead minnow), Oryzias latipes (Japanese medaka), Hyalella azteca, Daphnia magna, Vibrio fischeri, Lampsilis cardium, Ceriodaphnia dubia, and...

This is a map of current snow basin indices across British Columbia. Snow basin index mapping is based on analysis from the River Forecast Centre, and is meant to accompany the Snow Conditions and Water Supply Bulletins that are published for data from January 1st, February 1st, March 1st, April...

The Canadian Hydrospatial Network (CHN) is an analysis-ready geospatial network of features that help enable the modelling of surface water flow in Canada. The six main layers and feature types are: flowlines, waterbodies, catchments, catchment aggregates, work units, and hydro nodes. Where...
