E.........Back in the early 1980's , a rail car derailment along S.R 350 , caused a rail tanker car of vegetable oil to dump into the Little Juniata River above Spruce Creek . I saw the mess a day or two after the wreck. There were what looked like white coagulated serving tray size masses of the oil,floating on the stream. The most shocking thing, was the numbers of floating dead fish, among the masses of floating coagulated oil in stream eddies. I lived only about 8 miles from the spill site, and was then a serious fisherman. Though there was a clean up, from my understanding , it took years for the trout population to come back to a fish able level.
Though living so close to the stream , I was busy with a 60 + hr. a week job , and never took time to fish there. .....oldwood
