    Given today is a record setting rainfall in our area...
    Given the storms ripping through the states south of us...

    How much rain does it take to raise the level of the rive by any significant level?
    ie a foot or more?
  2.  
    it would take a lot of very sustained rainfall to raise a river.

    Think of the length of the river, the volume you would add by adding a foot of depth in that river. Then you have to subtract the outflow from the river (the flow and the infiltration). It's an awful lot of rainfall.

    Most flooding (and I say most) is in the spring because of the ice in the water. Flooding from strictly rainfall isn't as common....

    yeah actually record breaking day (for today)

    as of 10AM we had met the record for rainfall on this day... and it has been raining since then i think

    If it has been raining that heavy along a good chunk of the rivers Basin.. you would think it would have an impact???
  5.  
    more rain also increases the rate of flow in the river....

    HIGH WATER ADVISORY ISSUED FOR WINNIPEG RIVER IN EASTERN MANITOBA

    Manitoba Water Stewardship's Hydrologic Forecast Centre has issued a high water advisory for the Manitoba portion of the Winnipeg River in eastern Manitoba.

    The river has been rising steadily since early May after several significant rains in the area.

    The level of Nutimik Lake has already risen 0.8 metres (2.6 feet) since early May and is expected to rise at least 0.5 metres (1.6 feet) more. A crest of 905.2 feet is expected at Nutimik Lake sometime around June 20. The normal summer level of the lake is 901.5 feet.

    The anticipated crest will affect low-lying portions of some recreational properties, parks, docks and some boathouses. Cottagers, boaters and fishers along the Winnipeg River are advised to take necessary precautions to protect their properties. The strong current will make boating dangerous so extra caution is advised. Inexperienced boaters and canoeists are advised to stay off the Winnipeg River.

    This advisory will be updated during the coming weeks if the flood prospects change significantly.

    Information on water levels is available at www.gov.mb.ca/waterstewardship.

    There are SO many rivers that flow into the Red, I doubt it'll have a <b>significant</b> effect.

    From the website, it looks like the Red is slightly above normal summer levels right now - 7.34 (normal is 6.5).
