MEDICINE HAT – FLOODING – Flood update from Southern Alberta… The conditions have subsided slightly, but there is an issue across many parts of the province. The flooding and concerns are caused by heavy rainfall, and a melting snowpack in the mountains on the western boundary of Alberta.
Earlier a flood alert that had been issued by the Blood Tribe near Lethbridge Alberta has been reduced.
The Oldman, St. Mary, Belly and Waterton rivers are receding. The State of Local Emergency is still in effect. The reception centre at the multi-purpose building will remain open through the weekend. The Tribe has now shifted into recovery mode.
The Emergency Operations Centre (EOC) continues to receive updates from Alberta Environment and will continue to monitor South Saskatchewan River conditions. The river was flowing at 2,914 cubic meters per second at 8:30 p.m. Alberta Environment forecast a peak of 3,100 cubic metres per second to occur after 9 p.m. on Saturday.
The peak could last for a significant period of time, potentially more than a full day. The EOC is planning for any issues that may develop should the peak be sustained.
Hatters are asked not to venture near the river until the river flow subsides. Information on river flow levels will continue to be communicated via the City’s website and social media.
City personnel continue to visit each of the properties potentially impacted by a sewer service disruption related to the issue at the City’s IXL lift station. Properties in the Red Zone may experience sewage backup. Individuals in the Red Zone are advised to close their sewer isolation valves and move valuables out of basements as a precaution. Individuals in the Yellow Zone may notice a sewer related odour in their basement, but are less likely to experience sewer backup. Closing the sewer isolation valve is discretionary in the Yellow Zone.
Once a sewer isolation valve has been shut off, residents are reminded they should not use water in their homes (for showering, flushing toilets, etc.) because the water will not be able to drain away. Additionally, residents should not open the valves until the City has communicated it is suitable to do so.
In all, there are 81 properties in the Red Zone and 376 in the Yellow Zone. A Reception Centre has been established at Strathcona Centre for individuals from these zones needing assistance or information. Environmental Utilities continues to work to stabilize the situation.
The Flood Information Line will continue to operate from 8 a.m. to 8 p.m. The phone number is 403-525-8600.
