A Michigan-based American Indian tribe wants to join a lawsuit demanding stronger action to prevent Asian carp from infesting the Great Lakes.
The Grand Traverse Band of Ottawa and Chippewa Indians filed a motion Tuesday in federal court in northern Illinois, which is hearing the case filed by Michigan, Wisconsin, Ohio, Minnesota and Pennsylvania.
They accuse the U.S. Army Corps of Engineers and Chicago officials of creating a public nuisance by operating shipping locks and other infrastructure that could let the carp enter Lake Michigan.
In its motion to intervene, the tribe says it wants to make sure the case devotes enough attention to its treaty-guaranteed fishing rights.
A hearing on the suit resumes Sept. 7.
