    Over the last year, the neighbors large tree feel across the creek in the back of my property. Unfortunately due to way the sun was last night I couldn't get a good picture of the tree. The tree is about 30" around at the base. I cut the small tree in front it into the creek on Saturday.

    When the tree fell down it caused more trees to pile up behind it. The large tree is the branch in the back coming up.

    This facing towards the opposite way of the large tree.

    I have no way of getting a track hoe, bulldozer, tractor into this area since it's a really thick woods. The area is very low too and I'd be worried about getting something stuck. This creek also provides drinking water for a very large ( > 1M people ) metro population. I'm sure they wouldn't be too keen on an oil spill in the creek. And I don't want to deal with government bureaucracy if something were to happen. Closest house is easily 200 yards away. I would of course make the neighbors aware what I'm doing. I'm not going to get the neighbor involved whose tree started all of this. I don't want to deal with the hassle, and I doubt they care.

    After evaluating the situation on Saturday, and Sunday I'm thinking about blowing the big tree up, and the dam up with Tannerite. Anybody have any experience using Tannerite to do this ? There was a thread awhile ago from a guy who was going to blow up a leaner with Tannerite but the thread kind of died.

    I'd like to get this done before the spring flood happen because the creek is starting to widen its way more onto my property and starting to cause some damage I don't want.

    Wow, lotsa wood! What about a long cable winch system? You can convert saws too.

    Kinda looks like a nasty beaver dam if you cannot get equipment in there it will be rough I do not think tannerite would work to well the only other way would be as Wood Wolverine suggested would be cutting and winching those lewis winches do one hell of a job . a pole saw is a big help with those messes Good Luck it is a lot of work

    My goal is to remove the dam as cheap as possible. That’s why I’m thinking Tannerite. It will probably cost me between $70 - $100 worth of Tannerite.

    I can care less about salvaging the wood. I also have no way of getting it out of the woods. I have more ash on the ground that what I’ll burn in the next 10 - 20 years, unfortunately.

    You nailed the beaver part. I have a guy coming this weekend to try and trap it before the season closes. DNR told me they blew up a beaver dam north of me in the same creek.

    You can get local LEO permits for dynamite for beaver control.

    That's a dam mess!
    Yeah I dunno if tannerite will do it...maybe if you use a ton of it, its placed strategically, and some luck.

    What’s a LEO permit ?

    From talking to DNR a few week about about the beaver it sounded like they used an explosives expert to blow the one up north of me. Was going to call him tomorrow and see if he has more information.

    Generally, the dnr won’t issue permits to blow up a dam unless you are making massive changes to a wetland. That’s what the DNR gives a permit for. They’d also issue a beaver control permit as they are considered a protected species.

    LEO is law enforcement.

    your sheriff would issue you an explosives permit so you can buy dynamite or similar for the actual work.

    At least in Minnesota that’s what the process is.

    When I called a few weeks ago he said he wouldn’t have a problem issuing a nuisance permit if we couldn’t get it trapped by the end of the season. I’m just not a fan of throwing an animal in the trash. That will be a last resort.

    He did mention that they let the sheriff know when they blew the dam up north of town. I’m going to call him back tomorrow and see if he has the contact information for the person that did the work.

    If I do go through with using Tannerite on it, it will be this Sunday. I’ll probably call the sheriff on Sunday to let them know we are going to be removing a “log jam”.

    Reactive target material will need to be confined to have any real effect. I envision boring a hole in the stem with a saw and placing it in the hole possibly working. I am not shooting off the cuff here. Fairly vast experience with those targets. Just setting them on that mess isn't going to do anything really.

    If that creek isn't too deep, some hip waders and a small saw need deployed into that pile (from the downstream side!). Without an excavator it's just a bunch of manual labor.

    The problem with tannerite or dynamite for that matter is you have to pack it; it in like a bullet, so the force coming out causes the results you want

    This was my initial plan but it's way too dangerous to do that IMHO. That tree weighs thousands of pounds, the last thing I need for it to do it roll onto me. That's my plan with the Tannerite, bore a hole into the tree with a a saw in the middle or on both ends and blow it up and cross my fingers that the current pushing from the back pushes it all through.

    Sure, I'll gladly cook and host. Just bring a saw and an AR. :D
