Jon Christensen in The Los Angeles Times: Lewis MacAdams, famed crusader for the Los Angeles River, dies at 75

Lewis MacAdams, a poet and crusader for restoring the concrete Los Angeles River to a more natural state and co-founder of one of the most influential conservation organizations in California, has died. He was 75.

“There is a hole in the L.A. River,” Jon Christensen, a professor at the UCLA Institute of the Environment and Sustainability, said. “Lewis showed us the spirit of nature that could be found, revered, and recovered in its most altered and almost unrecognizable form in the Los Angeles River.”
