Setting brush piles Help?
I second the other responses about hardwoods and bamboo being the best brush. We sank about 40 Christmas trees a few years back and made several nice size piles in high traffic areas for fish (river ledges, creek mouths, points, ect.) I can't help but think the fish didn't pass through the areas, but I can tell you that I had very very very little success on those piles. I even did as cray suggested and thinned them out.
I sank a oak limb on one of the spots the following year and it started producing.
The Christmas trees also made a huge mess of my boat!! Much more than hardwood or boo!
The only firs that I've caught fish on were in Hartwell. I had limited success but I did find fish on some piles a hand full of times.
