Lake Superior water levels in late December remained about a foot below normal, according to the National Weather Service office in Marquette.
Despite some heavy rainfall during September and October in the Lake Superior drainage basin, water levels were a foot below normal, but seven to eight inches above the record-low level set in 1925.
Above normal temperatures and lack of precipitation for 2005, 2006 and 2007 caused the lake's water level to come within an inch or two of record lows in 2007, but the situation has been gradually improving.
The highest December water level was 603.1 feet in 1986, while the low was 600.1 in 1925. On Dec. 1, 2007, it was 600.9, and it fell to 600.7 on Dec. 31.
Water levels in the Lake Michigan/Huron drainage basins also fell slowly in December, according to the NWS. They hovered nearly 15 inches below the long-term mean and just one to two inches above the record low established in 1964
