Agreement with TransAlta will help control flood, drought in the south.

A five-year agreement between the province and TransAlta allows modified operations at Ghost Reservoir for flood mitigation purposes from May 16 to July 7 each year, to adjust reservoir levels at three Kananaskis-area reservoirs year-round to supplement flows on the Bow River during dry periods, or provide additional flood storage. Modified use of existing water management infrastructure complements the province's other flood and drought resiliency efforts, including community-level mitigation, new flood hazard mapping, and the restoration of wetlands and riparian areas. Last year's agreement provided the province with up to 65 million cubic metres of flood storage at Ghost Reservoir during the high run-off season. The new agreement adds year-round control of reservoir levels at Barrier Lake, Upper Kananaskis Lake, and Lower Kananaskis Lake. Initial reservoir target levels will be set prior to each operating season based on the provincial water supply outlook, snowpack and soil moisture conditions, and prevailing weather patterns. However, water levels will fluctuate during the modified operations period to reflect ongoing risk assessments for both flood and drought. The Alberta government will provide TransAlta with $5.5 million in compensation annually for five years to offset the impacts that modified operations will have on TransAlta's ability to generate power at these facilities.
