The rain fell hard on Lyons, Colorado. In September 2013, it poured for days, soaking the foothills and filling the creeks and streams. Bonnie Newman wasn’t worried, even though her mobile home was next to the rushing water of St. Vrain Creek. A meteorologist friend told her things would be okay, and nobody had told her to evacuate. But after days of rain, sometime after 1 a.m., something changed. “Suddenly there was water,” Newman said. “Lots of water. It was a current of water, and it was right through my yard. ”Fire trucks pulled into the aptly-named Riverbend mobile home park, sirens blaring. Over a loudspeaker, a voice told everyone to leave. “I never got so much as a toothbrush,” Newman said.
