Changes were made to water flow out of Glen Canyon Dam. That led to more bugs in the Colorado River
Ted Kennedy sums up what he sees along the river in the Grand Canyon: “It’s buggy out there.” That is to say, an experiment to change the flow of water from a dam near the Arizona-Utah state line appeared to boost the number of aquatic insects that fish in the Colorado River eat. Scientists are hoping to better understand those results with a second bug flow experiment that started this month and will run through August.
