From The Pueblo Chieftain (Chris Woodka):
Repairs are needed in the channel downstream of the West Fourth Street bridge because flows were altered by construction of kayak course gates in Pueblo Whitewater Park. That caused the potential for washing out the base of the concrete levee on the north side of the Arkansas River. “The good news is that the tow of the levee has not been denigrated,” said Gus Sandstrom, president of the Pueblo Conservancy District, which is responsible for inspection, repairs and maintenance of the levee. “That will help us in getting the levees certified (by the Federal Emergency Management Agency).” The current project also will allow the district to install drains that will make future repairs less of a challenge. Voids of up to 3 feet deep have developed behind parts of the concrete facing, and the U.S. Army Corps of Engineers is still determining whether to replace or simply reinforce the facing with grout.
The concrete initially was poured in the 1920s and has become a canvas of whimsical paintings over the years.
Workers have constructed a temporary bridge across the river to reach the areas that need to be repaired. Originally, the plan had been to divert water along the river with a small levee at several gates. Now efforts will be concentrated on smaller sections in the most critical areas using coffer dams.
