Elizabeth Grossman, a Portland, Ore., resident and co-editor of Shadow Cat: Encountering the American Mountain Lion, will be reading from her latest book, Watershed: The Undamming of American on Sunday, July 21, at 4 p.m. at the CAST Performing Arts Center in Hood River.

Questioning the value of dams requires a serious readjustment in the country's notion of progress, a process frightening and threatening to some, daunting to all. Watershed examines the implications of dam removal to America's rivers and their communities by exploring the stories of a number of locales around the country where dam removal is now under consideration or underway.
