Water Regions within the RDN are the watershed groups used for water budget analysis and administrative purposes. Water Regions combine all named and unnamed subwatersheds within an identified region into a grouping useful for water management purposes. For example, the French Creek Water Region comprises the named watersheds of French Creek, Grandon Creek, Morningstar Creek, Carey Creek, Romney Creek, as well as several small, unnamed watersheds at the coast.Geoprocessing: Water Regions represent a Spatial Merge of the BC Freshwater Atlas Named Watersheds polygons.

Water Regions within the RDN are the watershed groups used for water budget analysis and administrative purposes. Water Regions combine all named and unnamed subwatersheds within an identified region into a grouping useful for water management purposes. This dataset represents the locations of hydrometric stations within the RDN water regions that are run by the RDN or the British Columbia Conservation Foundation (BCCF).From the Regional District of Nanaimo’s Drinking Water and Watershed Protection Action Plan:To understand the water balance within a watershed, hydrometric (streamflow, water level) and climate data are essential. The expansion of climate and hydrometric stations in the region has been a key success to-date. Streamflow is the master variable that determines the stream form, habitat diversity, and ecological and hydrological function. Streamflow is directly impacted by more intense droughts and rain events associated with climate change. Climate stations are currently positioned predominantly in the lower watersheds. Additional stations are necessary for data collection in the mid and upper watersheds to support both extreme weather event response and long-term water planning exercises. Senior governments are primarily responsible for hydrometric and climate monitoring networks, but the RDN will continue to support the addition of local stations that fill gaps in provincial or federal networks through identification of priority areas, coordinating site / land access, and occasional operational support funding.To view the Water Regions web mapping application: https://rdn.maps.arcgis.com/apps/MapSeries/index.html?appid=5ec9bd56b5374ef7814c0281db9b70f9
