Hi Wilda,
If your serious about establishing your own private fishery, happy to and can help you, send me an email austprivatefisheriesresources@gmail.com. My background, I am a fisheries ecologist with 15 years experience, including two state fisheries departments and have worked on some well known public and private freshwater fisheries. I will only help if your serious though as I don't have time to waste. By first impressions yes your dam could support trout, some good size ones too, but there will be some work involved on your behalf. Again, I will only help if your serious though.
