The level of Lake Superior rose about 3 inches in April, according to the International Lake Superior Board of Control.

Three inches is the amount the lake usually rises for the month, and the big lake now sits just an inch lower than the level at this time in 2012, but still 13 inches below its long-term level for May 1.

Water supply to the lake was a bit lower than normal for April, in part because snow and ice still locked up moisture across the watershed. That should change dramatically in May as rivers let loose and the last snow melts.

Meanwhile Lakes Huron and Michigan saw higher-than-normal rainfall and shot up a whopping 9 inches in April, the second-most for any month since 1918. That's good news for shipping interests and recreational boaters who have been dealing with near record-low water levels.

Even with that big April jump, however, the two lakes sit 22 inches below their long-term May 1 average and 6 inches below the level at this time last year.
