Assiniboine River:

The Shellmouth Reservoir water level rose 0.09 feet to 1410.58 feet in the 24 hour period ending this morning. Strong north winds which developed overnight added to the rise. The total reservoir outflow had temporarily risen above 2100 cfs this morning due to the strong north winds but was reduced to 2050 cfs near noon by operation of the conduit.

The reservoir inflow this morning was 2600 cfs and is expected to crest at 2650 cfs later today. Inflows will exceed outflows until June 8 at which time the reservoir water level is expected to crest at 1410.7 feet. The peak outflow will be controlled at 2100 cfs from now on if possible.  Near the time of the crest the 2100 cfs outflow will be entirely over the spillway. Rain and winds later this week could have a significant effect on the reservoir crest and the peak outflow.

The level of the Assiniboine River at Shellmouth bridge rose a quarter foot overnight and stood at 1354.95 feet this morning. The level is expected to decline later today in response to the reduced outflow.  Flooding of some low lying agricultural lands is taking place from Shellmouth Dam to Millwood. An aerial survey of the river valley from the Dam to Millwood will be done later today to determine the extent of flooding.

The Assiniboine River is expected to crest at Kamsack later today. Levels of the Shell River continue to decline slowly.

Red River, Eastern Manitoba:

 

Levels of small streams in the Nopiming Park area, where 90 mm of rain fell Monday evening, continue to subside but larger streams such as the Bird River continue to rise steadily and may not crest until the middle of this week  Localized flooding and additional difficulties with transportation due to washouts are possible. The return period of the rain which fell in the Booster Lake area last Tuesday, considering both the amount and intensity, is estimated to be about 100 years.

Saskeram Area:

Flooding will continue in the Saskeram area for many weeks due to the large amounts of water in storage in the marshes and lakes. Bracken Dam is being operated to reduce levels to the extent possible. MAFRI, is working with the T.M. of Kelsey and Crown Lands to help farmers affected by flooding. Levels of the Carrot River continue to decline while levels of the Saskatchewan River are relatively steady.

Red Deer Lake:

The level of Red Deer Lake appears to be at its second crest about one-third of a foot lower than the crest observed in early May. While the lake is very high, all properties remain protected by dikes and access to the area has not been impeded.

Red River:

The Red River crested at 10.1 feet over the weekend and stood at 9.95 feet this morning. Levels are presently declining from Grand Forks northward but this will be temporary as another crest is already developing in the Fargo area due to heavy rains late last week. With additional rain, possibly heavy, developing on Thursday, the next crest on the Red River may well exceed that which just passed. More detailed information will be provided in the days to come.
