Riser Boards?

[UndercoverBrother]

Anyone that has used Riser Boxes on their duck holes,

I pulled my boards out and let the water down a while back,

Any tips on leak proofing them when I put new boards back in, etc.

I read somewhere to tounge and groove them so they make a joint.

What I pulled out were standard 2x8 boards and they leaked a good bit last season but not enough to cause a problem.

we use the same boards but we weive plastic tarp, or any type of heavy plastic between to water proof it. we dont have any leaks. we usually have to pull the boards to let some water run off bout half way through the season cause we start holding too much water.. jt

we use silicone tween the boards and round the edges...never have leaks

Tongue and groove boads work good. Another good tip for larger boads that you plan on reusing is to drill a hole through the boad and drive some short pieces of rebar on each end to give you a handle when pulling them.

Quit using tongue and groove myself. Works great, but hard to get apart in the spring (because they swell and become inseperable when wet ). I usually wound up tearing them up getting them apart with pry bars.

Here's what I suggest instead: use standard treated lumber and block them into the structure with wedges so they don't float off. Dump a pile of fine sawdust in front, which will rise with the water, lodge in cracks between the boards, swell when wet and work like a charm. Use expandable foam available in cans to fill the voids between the steel riser and board ends.

I just take a handful of gumbo and smear it into all of the cracks.....God put gumbo here for a reason

Does anybody know where I could get a few of the risor boxes? I want to put in 2 or 3 for next year. thanks

I like wingman just use gumbo too, but I usually dont have to worry about no leaks, the beavers always fix em

We have a tail water recovery system at the farm and have about 35 flashboard risers. Tongue and groove works for me becaused I am always adjusting during farming season. I stay away from silicone and F-26 because I end up cutting the boards out (if I used it) in February when the conditions aren't always good. There are many sources for risers and include most welding shops. I have also used Trex lumber instead of wood to keep it from swelling so bad. The tarp method is not bad if it is leaking. I don't have beavers, so I don't have them to help. You may contact DU, they help some folks get riser pipe if you hold water according to their program. Problem is there is usually a waiting list. Good Luck.

I like t & g also. Squeeze in some mud around the edges and you are done.

I just use a shovel and hoe and put some gumbo mud in front/water side of the riser boards. Never leaks.

If your leaks aren't too bad, you can take a bag of kitty litter and sprinkle it in the water in front of the boards. It swells up in the cracks and does a great job. Beats the heck out of getting shoulder deep in buckshot. I learned this trick from one of the MDWFP waterfowl specialists, and it sure has helped me in the rice fields.
I don't do it any more, but we used to cut the top and bottom of the boards at a 45 degree angle. Kind of a poor man's tongue and groove for a 2 inch wide board.
