Lake Superior has risen more than twice its normal rate for the month of May, adding 9 inches to its water level since April.
As the Associated Press reports, Lake Superior usually gets about 4 inches higher each May. It is the second-biggest monthly jump for the lake since 1918.
The big lake now sits just 7 inches below its long-term average for June 1 but is now a full 3 inches above its level at this time last year, the International Lake Superior Board of Control reported Friday, according to the Duluth News Tribune.
The paper adds that both Lake Huron and Lake Michigan rose another 5 inches in May, compared with the usual 3 inches for the month. This is good for the Great Lakes shipping industry, the AP says, because freighters have had to cross the lakes with less than full loads, increasing prices and energy use and raising costs for raw material shippers.
Meanwhile, KARE 11 reports that invasive species such as Asian Carp are on the docket this weekend for a meeting of the Council of Great Lakes Governors on Mackinac Island, which began Friday and ends Sunday.
The Washington Post reports that Illinois Gov. Pat Quinn said Saturday that separating the Great Lakes and Mississippi River systems is the “ultimate solution” to prevent voracious Asian carp from overrunning the lakes, a potential step toward resolving a longstanding regional feud.
But Indiana Gov. Mike Pence poo-poohed the notion, telling the WashPo it would “cost thousands of Hoosier jobs and cause additional harm to many Hoosiers to manufacture and grow our products.”
Four governors are scheduled to attend: Rick Snyder of Michigan, Pat Quinn of Illinois, Mike Pence of Indiana and Scott Walker of Wisconsin.
Minnesota Gov. Mark Dayton did not attend.
