Northwest Water Tool: a decision support tool for surface water resource management

Description:A representative model of streamflow across Northwest BC has been created using detailed climate, topography, and vegetation information. Streamflow estimates were generated using a combined water balance and statistical approach. These estimates were then integrated with BC Freshwater Atlas watershed data and information on existing water allocations and environmental flow needs to support the development of a decision support system. The decision support system uses a map based interface to provide users with a watershed based view of the monthly water availability data for any location in the Skeena Region of the Ministry of Forests, Lands and Natural Resource Operations. This approach builds upon the learning from the development of the Northeast Water Tool (NEWT), and extends on its capabilities by also providing the results of hydrometric analyses for gauged watersheds in the study area, including the recent update to the Skeena Streamflow Inventory. This presentation will describe the challenges and solutions encountered during the modeling process as well as the guiding principles and objectives for the development of the decision support tool - the capabilities of which will be demonstrated.
