The U.S. Army Corps of Engineers is forecasting a three-inch rise in Lake Superior water levels during April and expects the lake to remain above average through summer.

The level changed little during March, which is typical for the month. The lake's level falls every winter and rises every summer.

In its update Friday, the Corps said Lake Superior is about seven inches above the long-term monthly average for April. However, it's six inches below the level seen last April, which was three inches below the record high set in 1986.

Elsewhere, Lake Michigan, Lake Huron, and Lake Erie are even more above average than Lake Superior but have fallen from last year's record levels. Conversely, Lake Ontario is 13 inches below the long-term average and down more than two feet over the past year.

The Corps said high water levels are expected to continue for at least the next six months and flood-prone areas are expected to remain vulnerable. High water levels have led to increased erosion and flooding around Lake Superior and the other Great Lakes in recent years.
