What is the proposed project?

The Municipal District of Taber is proposing the expansion of an existing emergency spillway to divert overland floodwaters and stormwater runoff within the St. Mary River Irrigation District to the Oldman River. The project would be located mostly on private lands near Taber, Alberta. The expansion would increase the diversion capacity of the existing spillway from approximately 7.6 m3/s to 40 m3/s.
