HYDAT Flow Gauge Watersheds - Ontario REPLACED
Coordinate system: 4269 - "NAD83"Abstract:
Retirement note: please note that this dataset has been retired and replaced by Ontario Integrated Hydrology Data, which is available from the Land Information Ontario (LIO) Warehouse.
HYDAT is a water database containing data on daily and monthly means of flow, water levels and sediment concentrations (for sediment sites).
This data is stored as series of shapefiles. The spatial layer symbolizes known HYDAT FLOW gauge locations that are part of the Environment Canada/Ontario Ministry of Natural Resources Cost Share agreement. For each of these gauges, there is a shapefile containing a watershed. The name of the watershed shapefile contains the StationID of the gauge. Watershed boundaries were defined using NRVIS data and the Provincial Digital Elevation Model produced by the Water Resources Information Program (WRIP).
A separate MS Access database stores a series of watershed characteristics that can be linked to the shapefiles. These characteristics include;
Supplementary data in shapefile and tabular format can be used and are available for download from the additional documentation section.
