Pond Boss Forums POND CONSTRUCTION Renovating a Pond or Lake? 2.5 Acre Pond Gone! work/restroation thread

BLUF: The pond was 18" below overflow with a seep, it has gone a few inches lower over the summer so I decided to chase One Gremlin One time. I'm asking for any advice you all have had on plugging a known seep.

The pond project has gone very well from what I actually expected. There is one seep that has been located and is exactly where Mose got the dozer struck and messed up the formation underground in Aug '22. To compound the issue/problem it appears they buried a couple trees under the road when I wasn't on site for that one part of the work once they winched his dozer out.





A couple weeks ago on 23 Aug we got +2" of rain and I was on site and checked for the seep(s) along the entire edge of the pond. Only one was found as noted - right where the dozer went in.







This is where I'd like folks advise/constructive additions to the process [Actions on the Objective] as I have only plugged one seep and that was documented above in this thread.

1. Start buy digging a 12' long trench, parallel to the pond, at the base of the hill that wasn't disturbed by the original excavation in '21 or the work done in '22 to remove a hill that was collapsing into the pond road. The trench is a far from the pond edge as possible.

2. Dig down in that 12' long trench until we cross the seep and dig at least 2' down past the last wet/water/seep. It may be infiltrated with water add 3-500#'s of bentonite bottom and see if we can get any bentonite slurry to flow into the seep/hole this is pure conjecture but we'll be ready with a slurry pan and 4gpm pump.

3. Once the bentonite is in and one the edges of the trench fill and pack the trench with regular clay, add bentonite to it and on top. Fill trench and top with material.

4. Dig out the seep and tree trunk.root from trench to pond, add 500-900#'s of bentonite into the trench and close to the opening, fillwith reglulr clay and top and sides with remaining bentonite.

5. Remaining Clay packed along the pond edge on/around the edge of the disturbed ground.






We're getting after this next Thursday the 14th so timely ideas/advise is encouraged. 💦
