Red River update

The Hydrologic Forecast Centre of Manitoba Water Stewardship advises that the Red River continues to rise due to heavy rainfall June 6-12, 2008. The crest is presently at Grand Forks, North Dakota.

At Emerson the river has risen 13 feet since early June and is expected to rise another 6 feet before it crests on June 22. At Ste. Agathe the river has risen 8.7 feet since early June and is expected to rise another 4.9 feet before it crests on June 24. In downtown Winnipeg the river level this morning stood at 8.1 feet above datum, a rise of 1.7 feet since early June. It is expected to crest between 9 and 10 feet above datum June 24-26.

Public Works and Government Services Canada (PWGSC) will continue to operate St. Andrews Dam at Lockport to maintain levels below 8.5 feet (Forks walkway level) in Winnipeg for as long as possible. However a minor inundation of the walkways is expected for a period of one week beginning this weekend.

Levels just upstream of St. Andrews dam have been declining as usual due to opening of the dam. PWGSC will issue information regarding operation of the locks for boat traffic. River levels from Selkirk to Breezy Point will rise 4 to 6 feet above normal summer levels which will not present any significant difficulties.

While the Red River will be well above average for the next few weeks it will remain well within its banks unless additional widespread heavy rain develops during the next few weeks. Boaters and canoeists are advised that the river current will be stronger than usual for the next few weeks, and therefore caution is advised.


  1. Yup, didn't catch anything when I went fishing this weekend-probably because of the high water. Whenever it's high my luck drops.

    Looking at the models, it looks like there could be some nice storm chances for the next few days. Hopefully we see some severe weather.

  2. CAPEs are already high over Southern Manitoba, up to 1000
    J/kg and it isn't even noon yet!. Steep low level lapse rates as well. 0-6km bulk shear is 30 to 40knots, sufficient for some large hail storms. With the cold air aloft, steep lapse rates, and increasing instability it should be expected that a few severe storms may form this afternoon all across the Southern Prairies. Of course these would be airmass type storms, that may not last very long but the risk is certainly there.

  3. PASPC is suggesting South-Western Manitoba may be in for some severe storms tonight. They note that even a few supercells are possible....Something to watch.

  4. Yup, in their latest discussion they note a Moderate Risk of severe storms there, with CAPE values exceeding 2000 J/Kg by 18Z! Definitely something to watch later in the day.

  5. The cold front is producing a line of thunderstorms at the Sask. / Manitoba border.
    Whether that line can hold together waits to be seen!!!

  6. Things are really starting to light up in southwestern Manitoba!
    A storm has just exploded heading toward Manitoba border!!

  7. WOW
    There are many warnings out for severe thunderstorms now!!
    Looks like a squall line is starting to form now!
