I think I'll tell my story.
I bought two 5 acre lots near Townsend in the mid 80's. Running through the middle of one of the lots is a spring creek. It has always had a population of small wild rainbow trout. The water is 58 degrees year round. I decided to feed the fish even though I lived in Nashville. I installed two feeders controlled by timers that dispensed food into the creek. They would go off twice a day. Since I was here in Townsend at least once a month I could keep the feeders supplied with chow. The trout grew huge. Paula caught her first trout in the creek when we were dating and has fly fished ever since. TU chapters and FFF clubs would hold outings on the property. One fellow caught a 22" rainbow, the largest trout of his life. A Boy Scout troop would camp down there every year. I brought in PortaJohns for any group that wanted to enjoy the property. Everything was great. Locals would fish there but I didn't see any abuse. I eventually built a home, moved to Townsend and Paula and I got married and we live there now.
Then one of our neighbors put their house on the rental market. The abuse started. Tourists would walk down to our now posted creek and catch 15" to 24" rainbows and kill them. I sent the local police to the rental house one time to file charges for tresspassing. You could see these huge fish and the tourists couldn't resist. After several confrontations I decided to let the stream go back to it's natural small fishery and hopefully tourists wouldn't find it so appealing. Over the years friends and I installed Lunker Bunkers and did a lot of bank stabilization. Then I decided to stock brook trout. I got permission from TWRA which had to be approved by the National Park Service to stock them. I had 400 brook trout fingerlings flown in from Pennsylvania. Walter Babb and I stocked the fingerlings. The next day I went down to check everything out and I could smell chlorine. I drove upstream to a trout farm and found that the owner had used Chlorine to kill algae in one of his ponds. Of course it washed down into the creek and killed every fish in the stream including the brook trout. He told me he would do anything I wanted to get the stream back including raising brookies for me at no cost. I didn't turn him in. I should have. About a month later, a neighbor upstream breached a mill dam that had held back silt and gravel for 50 years. It completely filled the stream with gravel and silt. I talked to the Tennessee Department of Health and Environment about what happened. They suggested I file a complaint and they would file charges. Again, I didn't want to get on the wrong side of a neighbor. Over a period of years the gravel washed it's way down stream. But, I gave up. I don't like to go down there anymore. I probably haven't seen that stream in a year or more and it's only a two minute walk from my house. When I go down there, it makes me sick. When I go fishing in the Smokies it makes me feel good. There are a lot of awful things that occur when you own a trout stream. I've been offered 6 times what I paid for that lot and some day I may sell it with no regrets.
