Nearly two years passed before workers could control the Colorado River's flow and stop the flooding, but the river was effectively dammed in the early part of 1907 and returned to its normal course. The flood significantly enlarged the channels of the New and Alamo Rivers. Some water still flowed after the dyke was repaired, as the larger channels collected and carried agricultural runoff to the Salton Sea.

In 2006, through another binational project, Mexicali finished building a second wastewater treatment facility to treat the 10 to 20 million US gallons (38,000 to 76,000 m) per day of raw and partially treated sewage that was being discharged into the river. In May 2005, the New River was
