After this weekend, it's clear why Louisville is often referred to as Derby City, but the inspiration of one of its other nicknames — River City — is the subject of a new documentary that debuts Monday, May 6 at 6 p.m. on KET.

"This is the Ohio; Life Death Rebirth of the Beautiful River" will explore the 981 miles of the Ohio River, from Pennsylvania to Illinois, by examining its natural beauty, industrial history, and cultural impact — including how it influenced music — while assessing its future.

The one-hour documentary was written and produced by Morgan Atkinson, a Louisvillian documentary filmmaker who has covered many Derby City subjects throughout his career, including:

The Louisville Free Public Library
Beargrass Creek
The Falls City Fountain

In a trailer for the film, Atkinson calls the Ohio, "the most engineered river in America."

If you miss the premiere tonight, don't sweat it — the film will air 11 more times over the next two weeks. See the full schedule.
