A DC 6 drops material during a poisoning operation at Scofield Reservoir in September of 1977. The point of the effort was to kill all the trash fish in the reservoir, restock it with fingerlings and let it sit a year so introduced fish could grow before opening it for fishing again. Some opposed the operation due to the drought which left the reservoir at such a low level and others were concerned about the rotenone that was being used in the operation.
