Flood Report for Manitoba
June 13th, 2007
Most areas of southern Manitoba received 10-20 mm of rain during the 24 hour period ending this morning. Rainfall continued in the U.S portion of the Red River an in the Whiteshell as of noon today. The U.S. portion of the Red River is expected to receive about 25 mm of rain from this latest weather disturbance while additional rain in the Whiteshell will be less than 10 mm.
Another disturbance is expected to bring additional rain to eastern Saskatchewan tomorrow night and southeastern Manitoba on Friday and more rain is likely Sunday night to Monday according to information from Environment Canada and 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 appears to be near the crest. A visit by Water Survey of Canada this morning revealed that 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 or somewhat below 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:
The Red River rose 0.8 to 0.9 feet from Drayton, N.D. to Winnipeg during the 24 hour period ending this morning. Predicted crests have been increased somewhat due to today’s significant rain in the U.S. portion. Additional rises of 2-3 feet are expected from Emerson to the Floodway Inlet while rises from Winnipeg to Selkirk should be in the 1-2 foot range. The crest is expected at Emerson on June 18 and at Winnipeg June 22. The river level in downtown Winnipeg this morning was 10.4 feet and is expected to crest at 12.0 feet based on normal weather conditions from now on. The normal summer level is 6.3 feet. The crest could be somewhat higher if heavy rain develops Sunday to Monday.

Assiniboine River:
A high water level advisory continues for the Assiniboine River from Shellmouth Dam to Millwood. The river in this area has risen slightly due to the rain but should remain generally within its banks unless heavy additional rain develops later this week or next week.
The Shellmouth Reservoir water level rose slightly to 1410.79 feet during the 24 our period ending this morning. This is the highest level so far this year and has raised the spillway flow to 2190 cfs without wind. There has been no flow through the conduit since 10 a.m. June 7. The reservoir inflow remains at 2150 cfs this morning. While reservoir levels show that local inflows have increased, it appears that there will not be a significant rise in flows at Kamsack due to recent rainfall. Some further rise is expected on the Shell River. As a result the reservoir water level and outflow is expected to change little during the next 5 days.
River levels from St. Lazare to Brandon will rise somewhat, mainly due to rainfall runoff from the Qu’Appelle River which appears to be at it crest this morning. There is not threat of flooding in this portion unless much more rain develops this month. Additional disturbances are expected to bring more rain to the Assiniboine watershed tomorrow night and again Sunday night.

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.
