Lake Winnipeg may rise seven inches in the next month, Manitoba Hydro stated in a release Monday.

Hydro based the prediction on above average rainfall for this time of year.

Lake Winnipeg-area residents and those downstream on the Nelson River were advised levels would be higher than usual and remain that way throughout summer.

High water levels have resulted from an influx of rain water pouring into Lake Winnipeg from the Winnipeg River, Saskatchewan River and Red River tributaries.

Hydro said the Winnipeg River alone has taken on 50 per cent more rain this spring than usual.

Despite its best efforts to maintain high outflows into outlet channels like the Nelson River, Manitoba Hydro said Lake Winnipeg levels are more than 217 metres above sea level and may rise around a fifth of a metre by the end of July.
