Resident K. Kermani captured these pictures and videos of Boulder Creek as it raged through the downtown areas of the city on the first day of the 2013 flood. The situation worsened considerably in the hours to come. JLC is featuring special coverage of the Colorado floods and how property owners and contractors are coping with the cleanup and repairs.
Boulder Creek rushing through downtown Boulder during the first day of flooding, but it wasn't done rising. The water exploded from its normal seasonal flow of 100 cubic feet per second to 5,000 cubic feet per second--more than double the previous highest rate ever recorded.
Water moving at 10 mph pushes with a force of 300 pounds per square foot. Water moving like this is a virtual bulldozer--even without its battering rams of floating logs and debris.
