Cold and wintry weather may cause a dramatic drop in water levels in the St. Louis region, and elsewhere, the Corps of Engineers and industry groups urged caution in icy conditions. Bernie Heroff, chairman of the River Industry Action Committee (R1AC), the industry group that works closely with the Corps of Engineers and U.S. Coast Guard to manage the Upper Mississippi River during times of extreme conditions, said the extreme cold weather forecast for a large region from St. Louis north could potentially lower the stage at St. Louis to -3 to -4 feet beginning January 14 or 15. However, dredging that has been done over the past few months has prepared the region for the levels, he said. Heroff said the drop should be moderated some due to extra water coming off the Illinois River, hydroelectric release from Bagwell Dam on the Missouri River and the release of some of the water above Melvin Price Locks and Dam at Alton, Ill. In the past, without moderating influences, it was not unusual to see a 5-foot drop in St. Louis from an "ice bite," he said. |
