That’s a good point Tony. I am interested to see how it all works out.
As a quick update, we are going to go with 4-6” stones on the bottom of the stream to give it some “staying power”, especially on the banks where kids will be climbing in and out, and then add some 0.5” pea gravel after to soften it for walking on. We are going to put landscape cloth underneath, and have the stone come up to 3 to 6” above water level, and then have the topsoil come down and butt into / bleed into the stone, and then erosion seed the topsoil. Our hope is that this design helps lock everything together.
