Watershed boundary delineated for Canada-BC hydrometric stations. Currently, watersheds were delineated using 1:50,000 scale boundaries in 1996, and many watersheds encompass entire drainages, instead of just the upstream watersheds. Note - Not yet available, but we are in the process of generating BC hydrometric station upstream watersheds using updated base data, using the following method: Within BC, watershed boundaries are based on the 1:20,000-scale Freshwater Atlas fundamental watersheds, and trimmed using the BC TRIM DEM used to approximate the height-of-land at the station locations. Outside of BC, but within Canada, watershed boundaries were approximated using Canada CDED DEM data for delineation (no "stream burning" was used) and some manual editing of boundaries was done to approximately match hydrology data after the fact.

The Grasslands National Park monitors daily the peak flow rates of the Frenchman River and Rock Creek every year from March to August; this measure reports on the integrity of a natural disturbance process by comparing the current distribution of peak flow rates to a historic baseline from the early 1900s.

The City of Montreal measures air quality in the form of a numerical value called the “air quality index (IQA).” This data set provides access to historical IQA values, which are updated daily. ***Note**: the IQA systems do not change time: they always use Eastern Standard Time (EST) and not Eastern Daylight Time (EDT). Thus, during daylight saving time, there is a one hour lag in the data. For example, a measurement recorded at 12 EST is that of 13:00 EDT.* Daily values, updated every hour, are available [here] (rsqa-air-quality-index). The [station list] (rsqa-list of stations) and [sectors] (rsqa-geographic-sectors) linked to RSQA data are also available.
