Whether the newly-admitted states took title to the entire beach surrounding the Great Lakes under the federal equal-footing doctrine

QUESTION PRESENTED Under federal law, on admission to the Union a state takes title to lands underlying navigable waters, up to the “ordinary high water mark.” On the seashore this mark is the average high-tide line, which typically falls partway up the beach. But this Court has yet to clarify how the high-water mark is defined on nontidal lakes, such as the Great Lakes. The question presented is whether—in conflict with the rule on the seashore—the newly-admitted states took title to the entire beach surrounding the Great Lakes.
