Colorado River flow now part of caddisfly battle in Bullhead City
The idea was to lower the flows while temperatures were still warm enough to dry out the caddis larvae. That required buy-in from local merchants and the Bureau of Reclamation, local tribes and others. They were able to do it, and on Aug. 27, the first of two flow reductions took place. When the river dropped, people pitched in for a day of river cleanup.
