PVC and tires don't break down like wood does. I think I would have to consider them to be permanent even though it may be possible to remove them.

I haven't read the regulations word for word but I did write dnr and they sent me back an email saying its illegal to sink anything in Patoka Lake. If I remmeber right the wording said all dnr managed properties.

I haven't fished any tournaments but I am surprised anyone fishing a tournament would do something that is illegal. Isn't there a lie detector test taken for the top finishers? I had heard there was maybe not. It seems that would be a good question to ask a tournament fisherman.

Personally I would love to see DNR relax the regulation on placing habitat in the lake. And that is exactly what it is habitat. If it were placed in idle zones only I don't see where it would create major problems.

Enough habitat? How can one determine enough? I don't think I have ever seen too much habitat.
