This presentation will explore climate change and flow regulation impacts on daily and annual river discharge variations and trends into Hudson Bay, the Nechako and Fraser River Basins over the past half-century or so. The first part of the presentation will focus on the 3.7 million km2 Hudson Bay drainage basin for which daily observed streamflow data from the Water Survey of Canada, Manitoba Hydro, Ontario Power Generation and Hydro-Québec for 21 rivers were used to analyze the basin from 1960 to 2016. Decadal hydrographs were developed to assess the changing hydrological regimes in both regulated and unregulated sub-basins and spectral analyses are used to infer the dominant modes of temporal variability on the river discharge input to Hudson Bay. While the unregulated systems exhibit signals of climate change, these remain secondary relative to flow regulation even at the larger Hudson Bay drainage basin scale.

Combined sewers are a legacy from early development in the City of Winnipeg, discharging land drainage and sewage to the rivers. They were the standard design practice prior to sewage treatment plants being built. Now dry weather sewage is collected from the combined sewer system and treated, however, overflows to the rivers do occur during rapid snow melt and heavy rain storms.
In order to control and reduce Combined Sewer Overflows (CSO) in Winnipeg, the Province of Manitoba issued the City of Winnipeg Environment Act (EA) Licence No. 3042 on September 4, 2013. This presentation will focus on the CSO Master Plan for the City of Winnipeg and how the new CSO EA Licence will change the way combined sewer districts are operated and redeveloped in the future.
