Eastern Manitoba:

A high water advisory remains in effect for Whiteshell and Nopiming Parks. The level of Bird Lake may have crested at a record high level yesterday according to local observers. A previous crest near this magnitude occurred in 1974. A boat survey by a local lodge operator yesterday indicates that 40 boathouses and 5-6 cottages have been significantly damaged.

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. Lake Of The Woods has risen 0.6 feet since mid May but remains nearly one foot below its average level for this time of year.

Red River Watershed:

The Red River rose more than a foot from Grand Forks to St. Agathe during the 24 hour period ending this morning with somewhat lesser rises from Winnipeg to Selkirk. Additional rises should range from 3 feet between Emerson and St. Adolphe and 1-2 feet from Winnipeg to Selkirk. The crest is expected at Emerson on June 18-19 and at Winnipeg June 21-22. The river level in downtown Winnipeg this morning was 9.6 feet and is expected to crest at 11.5 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 later this week or next week.

Assiniboine River:

The Shellmouth Reservoir water level rose to 1410.76 feet overnight due to about 30 mm of rain in the reservoir surface. This is the highest level so far this year and has raised the spillway flow to 2150 cfs without wind. There has been no flow through the conduit since 10 a.m. last Thursday. The reservoir inflow has risen somewhat due to local inflows from the rain and was estimated at 2150 cfs this morning. The flow at Kamsack continues to decline but may rise later this week due to heavy rain last night, especially in the Whitesand River watershed.

The reservoir water level is expected to change little during the next 5 days, but there is considerable uncertainty at this time since the effects of last night’s rain has not yet reached monitoring sites on streams.

River levels from St. Lazare to Brandon will rise somewhat due to rainfall runoff from the Qu’Appelle River and other tributaries but there is not threat of flooding in this portion unless much more rain develops this month. Rainfall for tonight and tomorrow should be mainly downstream of the Reservoir. However another disturbance threatens to bring more rain to the Assiniboine watershed upstream of Brandon Thursday night to Friday morning.

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.

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.
