In 1962, the New Mexico Department of Game and Fish, together with the Service, conducted a thorough policing of "trash fish," including the Colorado River squawfish. in the San Juan River. The Abstract of the Job Completion Report and the Job Completion Report speak to the effectiveness of that activity on the squawfish ki II. The San Juan River and tributaries upstream from the Navajo Dam were rotenoned to eliminate trash fish species within the proposed impoundment area. A total of 3,870 gallons of rotenone was used for the Navajo, Pine, and San Juan Rivers. Lethal concentrations were effective on approximately 70 miles of the San Juan River, 15 miles of the Pine River, and six miles of the Navajo River. Fourteen species of fish were eliminated with this opera- tion. Very good kills were obtained dally the San Juan, where rotenone carried approximately Dam. in all three rivers, espe- lethal concentrations of 40 miles below the Navajo Abstract of Job Completion Report Development and Operations, as required by Federal Aid in Fish Restoration Act, State-Wide Rough Fish Control, Rehabilitation of the San Juan River, Federal Aid Project F-10-D-4, by Harold F. Olson (hereinafter "Job Completion Report"). A total of fourteen different species were collected from the San Juan and Piedra Rivers. The rotenone treatment was very successful. Good results, nearly total kill, (sic) was obtained downstream to Fruitland. New Mexico, approximately 40 miles below the Navajo Dam. This made a total of approximately 75 miles of the San Juan River that was treated. Job Completion Report at p.~. A copy of the Job Completion Report. supra, is attached as Exhibit "e."
