String of flood bulletins for Manitoba
The province of Manitoba has released a flurry of flood bulletins. Most of the overland flooding continues across southern Manitoba. Ice jam related flooding also continues on some major rivers and smaller tributaries.
Flows on waterways across the province are continuing to react to the run-off from the melt and water levels remain high on many waterways. Ice has moved out on some rivers but remains in place on others including portions of the upper and lower Assiniboine River. Ice jams are still possible and are difficult to predict.
Some of the snowpack remains in the western part of the Souris River basin, the Parkland region, the Duck Mountain area, the Riding Mountain area and northern Manitoba. Much of the snow has already melted in southern Manitoba, with snow remaining in wooded areas.
The flood watch has been lifted for the lower Red River and Netley Creek as water levels are receding but open water levels on the lower Red River remain high. Most Red River tributaries are declining, with the exception of the Morris and La Salle rivers.
With the operation of the Red River Floodway, the Red River in Winnipeg has crested yesterday and water levels at James Avenue were measured at 18.3 feet this morning. With the floodway in operation, water levels at James Avenue are expected to remain at 18 feet for the next week as flows on the Red River recede and flows on the Assiniboine River increase.
Ice is beginning to move along portions of the lower Assiniboine River from Portage la Prairie to Headingley, leading to a flood watch for that area. A flood warning has been issued for Dauphin lake.
A flood warning remains in effect for the Birdtail creek, upper Assiniboine River from the Shellmouth Dam to Holland, Rock and Oak lakes, and the Pembina and Souris rivers.
Outflows from Pelican Lake are at maximum possible discharge and inflows close to the lake are close to cresting. However, there is still a large volume of water to come and the lake is projected to rise high enough that flood protection will be required for properties around the lake.
A flood watch remains in effect for the lower Assiniboine River from Portage la Prairie to Headingley due to ice running, the Boyne River downstream of Carman, Plum Creek and the Brokenhead and Red Deer rivers.
A high water advisory remains in effect for Carrot river.
Water levels are approaching record highs at the Smoky Burn gauge in Saskatchewan. Flows on the Carrot River within Manitoba are influenced by upstream Carrot River flows and water levels on the Saskatchewan River where the two rivers meet. Conditions will be monitored as water levels on the Saskatchewan River remain low. Ice jamming on both rivers is a concern as ice remains intact in Manitoba. The backwater effect of ice jamming will influence water levels on the Carrot River.
Since flood conditions can develop quickly, people are reminded to be watchful of local waterways, and avoid driving through moving water.
Since run-off may occur quickly, landowners who normally store a portion of run-off in dugouts for irrigation or other water retention structures are encouraged to retain water.
