Flood Report for Manitoba
June 14th, 2007
Some areas of the Assiniboine watershed in eastern Saskatchewan and the Russell area of Manitoba have received 10-20 m of rain since yesterday morning. Rainfall in the U.S portion yesterday was heavier than expected with some areas receiving up to 125 mm.
Additional precipitation is expected in western Manitoba, especially areas from Miniota northward, today and tonight. Additional rain is predicted for most of southern Manitoba for Sunday according to Environment Canada. Additional rain is also predicted for the U.S. portion of the Red River watershed during the next few days, with another significant rainfall likely over the entire Red River watershed Sunday to Monday, according to the U.S. National Weather Service.
A HIGH WATER LEVEL ADVISORY CONTINUES FOR WHITESHELL AND NOPIMING PROVINCIAL PARKS
HIGH WATER LEVEL ADVISORIES CONTINUE FOR THE ASSINIBOINE RIVER FROM SHELLMOUTH TO MILLWOOD AND FOR THE RED RIVER
Eastern Manitoba:
A high water advisory remains in effect for Whiteshell and Nopiming Parks. The level of Bird Lake has not changed significantly since yesterday. The lake is a quarter foot higher than at the crest in 1974, making this a record high level. A survey by a local lodge operator has indicated that 40 boathouses and 5-6 cottages have been significantly damaged. Booster Lake and Flanders Lake which drain into Bird Lake, appear to have crested last weekend, so levels of Bird Lake will begin to fall slowly from now on, based on favourable weather. Additional rises in the level of Bird Lake area unlikely but cannot be ruled out if the wet spell continues.
Lakes in the Whiteshell are well above desirable levels, except those on the Winnipeg River which are near normal levels. The high levels are flooding docks and beaches but so far damages appear minimal. Logs have been removed from most dams in the Whiteshell. The dam at West Hawk Lake has not been opened due to high levels on Caddy Lake into which it empties. Problems due to high lake levels could persist of worsen if the current wet spell continues.
Lake Of The Woods remains well below its average level for this time of year.
Red River Watershed:
A high water level advisory continues for the Red River.
The Red River rose 0.6 to 0.7 feet from Drayton, N.D. to the Red River Floodway Inlet during the 24 hour period ending this morning.
Predicted crests have been greatly increased due to up to 125 mm or rain in the U.S. portion yesterday. Additional rises of close to 10 feet are now expected from Emerson to the Floodway Inlet with a crest near the end of June. This is based largely on an updated forecast for the U.S. portion issued by the U.S. National Weather Service. As a result of this update the Red River will be near bankfull levels in some portions in Manitoba at the time of the crest. The river level in downtown Winnipeg this morning was 10.7 feet and is expected to crest between 13 and 14 feet based on normal weather conditions from now on. The normal summer level is 6.3 feet.
The weather outlook is not good for the next 10 days, so even greater rises are possible.

Assiniboine River:
A high water level advisory continues for the Assiniboine River from Shellmouth Dam to Millwood. There has been little change in the water level and outflow at Shellmouth Reservoir since yesterday. Levels of the Reservoir and on the Assiniboine River from Shellmouth to Millwood should decline slowly from now on unless significant additional rain develops. Rain is expected tonight and Sunday.
The Shellmouth Reservoir water level has decline very slightly to 1410.77 feet with a spillway flow to 2170 cfs. There has been no flow through the conduit since 10 a.m. June 7. The reservoir inflow has declined to 2000 cfs this morning.

Northwest:
The level of Red Deer Lake remains very high but has declined about half a foot from the crest observed in early May and the second crest observed early last week.
Water levels remain very high in the Saskeram area west-northwest of The Pas. While no homes are flooded, there are continued difficulties with cattle due to flooded pastures.
