"Unity Reservoir in Baker County, Oregon, was chemically treated with liquid rotenone on October 17, 1962. Approximately 136 miles of streams and diversion ditches and seven small ponds, tributary to the reservoir, were treated with liquid rotenone prior to work on the reservoir. The reservoir at time of treatment contained 1,700 acre-feet of water and covered 320 acres. A total of 700 gallons of liquid synergized rotenone was used on the tributary system and 850 gallons in the impoundment...Chemical tests of water were made to determine rotenone content...The reservoir was restocked with rainbow trout...A successful sport fishery developed in the fall of 1963 for 6 to 10-inch rainbow trout."

Fintrol-5 was experimentally tested in six isolated gold dredge ponds in Sumpter Valley. The tests revealed all coarse fish in treated ponds were killed in a period varying between 7 hours and 144 hours; toxic water subbing from treated ponds would kill fish in downstream ponds if water table dillution was not too great; and, the period of toxicity varied from 2 days to 12 days in treated ponds, dependent upon rate of water exchange. One pond without water exchange was treated at a concentration of .075 ppb. All but 30 fish were killed. Title: Habitat Improvement Project, No. 26 Author: Oregon. State Game Commission.
