Colorado River trout are expected to benefit from the warmer waters and increased productivity, but some fear an outbreak of whirling disease could have a serious impact on the fishery. Whatever your feelings about the dam, its daily operation is a key factor to understanding the habits of fish in the river below. Glen Canyon Dam supplies up to 1.3 million kilowatts of electricity and river flows are dictated, in large part, by power demands.
