There’s a creek flowing beneath the streets of downtown Minneapolis — and most people walking above it have no idea it’s there.Bassett Creek begins near Medicine Lake, winds through parks and neighborhoods, then disappears underground before passing beneath Target Field and downtown Minneapolis. Along the way, it even drops through an underground waterfall before eventually emptying into the Mississippi River.So why did Minneapolis bury a natural waterway in the first place?After a Curious Minnesota listener asked about the creek, reporter Susan Du dug into its history. By the early 1900s, Bassett Creek had become badly polluted with sewage and trash. Rather than restore it, city leaders chose to put much of it underground — an expensive decision that created engineering and flooding challenges for decades to come.In this episode, host Erica Pearson and Du trace the hidden path of Bassett Creek, explore the choices that transformed it, and ask: Could Minneapolis ever bring the buried creek back into the daylight?
