Panel: Structures may be needed to boost lakes

(AREA) -- An advisory panel is recommending the U.S. and Canada consider using artificial structures to raise water levels in Lake Michigan and Lake Huron. The International Joint Commission announced its proposal Friday, following a 5-year study by scientists and engineers. The commission advises both nations on issues involving the Great Lakes and other shared waterways. Lakes Michigan and Huron hit their lowest level ever recorded in January after lagging well below normal since the late 1990s. The commission acknowledges their shared level was lowered by dredging in the St. Clair River at the south end of Lake Huron in the last century. But scientists say drought and evaporation are the biggest causes. The commission report suggests looking at placing structures in the river that could boost levels 5 to 10 inches.
