Abstract
Biological studies were conducted in 1966 on 921 miles of the Colorado River system, including parts of the main stream and those tributaries that are interstate waters. These studies showed that wastes from municipalities, mining activities and gravel operations seriously degraded the aquatic life inhabiting 83 miles of interstate waters. Also studied were 581 miles of intrastate streams in the Colorado River system, of which 97 miles were seriously degraded for aquatic life by man's activities.
