Leaking Dams

Always the sign of a good consultant, willing to try new ideas on his or her own property and then advise clients on best practices. Well done.

Bentonite impregnated geofabric. I just learned about something new. I've made one pond in my life so far - about 1000 litres (if it filled all the way) hand dug - in my life so far. I'm planning on building about many more over the next 5 years or so along with a bunch of swales to slowly lower the water. We have tons of clay here and tons of rain. I had to dig through lots of gravel like consistency stuff, but got down to clay and then pounded clay (about a food wide) wall from under the clay I had reached up to the top on the down hill side of the hole - didn't particularly take advantage of the topology, but it was a flat place under my swale's overflow. It held very high for a week or two. It holds okay now but about a foot or more under where I was hoping for. I'm going to keep experimenting - I was considering a liner but I'll just try another and maybe look into this bentonite impregnated geofabric.

I saw Geoff's video about the ducks when he tried sealing it that way. I adopted that program on Tarashire. It worked for us, sort of. The ducks have to be continuous. If we remove the ducks, the dam leaks. After watching this, I now wonder if gravity is our advesary. I think the walls of the pond are to steep. Just like the geocloth, I wonder if the duck glee settles instead of adhering to the soil like I thought it would. Hmmmm. Never has there been a Lawton video without impartation of knowledge/ideas. The single most valuable human on Earth at this moment. ;)

Beautiful pictures... beautiful ideas...

Just a thought... Why not develop a hemp textile, impregnated with tar, as was being done to close up the gaps in wooden ships for many many years? Hemp fibers were the only material capable of withstanding the harsh conditions out on the ocean. And when you create natural tar out of wood, you'll get charcoal as a by-product and fertilizer.

[@yLeprechaun]

What? Tar from wood? Please tell more. I'm very interested in this idea. We can grow hemp legally now where we are. Well, some varieties anyway.

[@brianwhite9555]

@@yLeprechaun, Wood tar, from en.wikipedia.org/wiki/Tar#Wood_tar "The heating (dry distilling) of pine wood causes tar and pitch to drip away from the wood and leave behind charcoal. Birch bark is used to make particularly fine tar, known as "Russian oil", suitable for leather protection. The by-products of wood tar are turpentine and charcoal. When deciduous tree woods are subjected to destructive distillation, the products are methanol (wood alcohol) and charcoal." Also, en.wikipedia.org/wiki/Pine_tar and en.wikipedia.org/wiki/Birch_tar

@@brianwhite9555 thank you, yes that's the source I got the idea from.

better a bentonite impregnated hemp fabric, the wood tar will leach, and the health effects aint great: en.wikipedia.org/wiki/Creosote#Health_effects

I can tell you that in East Anglia, where we receive little more rain the the Sahara, server droughts are a regular feature rivers and streams run dry even ponds will evaporate away if shallow, Norfolk where I now live is not short on clay whilst there are also extensive areas of sand and gravel deposited at the end of the last ice age. To get to the point the old traditional ponds are lined with puddled clay that then has flints rammed into the surface this seems to prevent cracking and the compromising of the puddled clay liner.

Thanks mate this was a great video as I have a similar problem with the rock.

Thank you Sir.

[@joecrablone286]

Sounds like a good situation for an underwater compost to accelerate the biological sealing processes.

[@TheKlink]

anaerobic composting, right?

[@joecrablone286]

Yes, just to feed the first trophic tier of organisms. Composting may not be the right descriptor, more like a feedstock that grows algae as it decays. Mollison described it as weighted crates of material probably in the center of the pond, where it can best handle the settling of nutrients.

Hey! About harvestwater What do you think about organic polyter ?

[@09conrado]

I often wondered if you could solve some of these leaky dams with a concrete vibrator. Get a layer of water in the pond, dissolve some manure or other gleeing agent in there, and then vibrate the mud so the fine particles will form a dense layer. It's just an electric hand-held device, but it's a lot of work for a big pond, as you'll need to keep raising the water and vibrate the edges of the pond ever higher. I remember someone on Paul Wheaton's permies.com showing a series of photos showing how they sealed a pond: permies.com/t/38201/Progress-Gleying-Pond-Pigs

[@yLeprechaun]

That's a great thread. Thanks for the share. Always people around to tell the guy doing it, it won't work, all the while looking right at it working. Lol

if i dug out a whole dam with a pick and a shovel and then it leaked id be fucked lol

Introduce beavers.

[@alexriddles492]

Or just plant birches all around the pond and wait for the beavers to appear on their own.

[@protyusgames4741]

@@alexriddles492 I was thinking of making a permaculture computer game where the animals would show up when certain system conditions were met. Just as you say.
