Baseline hydrology statistics (streamflow regime) has been generated for the Water Survey of Canadas (WSC) HYDAT stream gauges in the Southwestern Hudson Bay and Nelson River watershed system that lie within the Province of Ontario. The purpose of this study is to quantify the relationship between watershed function and streamflow regime. Four components of the streamflow regime were specifically studied: frequency, timing, duration and discharge. The resultant baseline hydrology statistics include: Information on streamflow regime for each of the WSCs HYDAT stream gauges, and A review and summary of the streamflow statistics at the primary watershed scale from the above findings. The baseline hydrology data product can be used by a wide range of businesses in the Far North. Applications include: land use planning, integrated watershed management, climate change studies and hydropower studies. The baseline hydrology statistics data package is distributed as a Microsoft Access Geodatabase. The monthly and annual flow duration curves and the mean annual flow are included in the Ontario Flow Assessment Tool (OFAT) web application.
