Experts took measurements with satellites and field photography. They found that the eight-state region gained 13,610 acres, while ocean coastal areas lost more than 360,000 .

Scientists say the Great Lakes' gains resulted partly from lower water levels, which enabled wetlands to form along the shores. But they also credit programs that spent millions of dollars restoring wetlands that were drained or filled for farming, housing and other development.
