What to do?

Do you have a pic of the landscape timber while being put in? I thought about using concrete blocks under the liner to make the wall.

Edit:
How much force do you think the wall will have to hold back? The bog at its current size is 9'x5'x18"

We used landscape timbers, drilled and stuck rebar through them, the ends are anchored in concrete.

Mine is around 27 feet long, 2.5 feet deep, 4ish feet wide. 38000 lbs of pea gravel. Still holding just fine.

Is there fish safe glue for attaching rocks together?

And tell me if my calculations are right please.
My bog is 10'x5'x1'. So 50 cubic feet.

I would need 100 bags of this? I went to lowes and the bag seems bigger than .5 cu ft.

Yep 100 bags. When I bought a few bags of pea gravel I bought it in the construction area of Lowes, it was cheaper than the stuff in the nursery area. I have not looked recently.

I had my pea gravel delivered by a truck, but I needed 38000 lbs.

Something doesnt seem right. Heres a pic of the bog.

I dont think 100 bags will fit in there. But maybe I dont understand pea gravel.

Buy about 10 and see how much they fill it up.

About ready to fill up the pond.
I just have a question on how to stop the debris from getting to the pump. I dont get alot but I dont want to damage the pump.
This is the pump im using

12V-18V DC Brushless Submersible Water Pump 898 GPH for Solar Fountain Koi Pond and Waterfall (1 Pack) https://www.amazon.com/dp/B01KC3UAN6/ref=cm_sw_r_cp_apa_i_sOG-CbQBS01QV

Could I use a bag around it?
