I come to you as a fellow landscaper looking for advice. I have read several books on the subject of aquaculture however my practical experience is slim. When my family moved into our current house we also inherited a fully established pond, fully landscaped and it looked to be in fairly decent shape. Over the last roughly 3 years however it has become evident that some things were not done correctly. That coupled with the destructive digging force that is a Jack Russell Terrier looking for chipmunks has rendered it to the condition that youll see in the following pictures. At one time the intent had been, or so I was told by the former owners of the house who were the ones who installed it that the original idea was for the pond was for there to be a bubbling spring at the far end of the streambed. In any case that explains the electrical connection at the head of the stream. As you can see it is made of flexible Butyl liner which happens to be in excellent condition. No known punctures or tears thank god. In the main pond you will see that the method used to secure the sidewalls involves the liner being folded over some sort of rigid plastic sheet and then backfilled with poured concrete. I dont know if this is a common practice for securing flexible liners but I have never seen it in any of the books that Ive read, so I can only assume it was another half-assed idea that the former owners invented. In any case as you can see the concrete is cracked and the plastic that is under the butyl has begun to cave in as well. The stream portion of the pond is secured in a different way. They simply cut the butyl so that in several places it forms tabs and then heavy pieces of sandstone were placed on these tabs. Which would seem to make all kinds of sense except that the stones on the tabs are on a slope, enough of a slope that when our Jack Russell goes digging for the chipmunks that live under the streambed, she causes the stones to fall into the river which in turn causes the wall to fall and the level of the pond drops anywhere from 2 - 4 inches. Another contributing factor to this is that as you can see the walls of the stream are quite steep. The soft loamy soil has begun to compress and therefore press on the butyl causing it to buckle. My next problem is that this is a fully established landscape. Much of the area where you see bare dirt will in another month or so be filled with several varieties of large, well established hostas, amongst other perennials. So my questions to you are this: What should I do? Remove some of the plants alongside the streambed so that the angle can be lowered so that the rocks cant fall in? Should I try to remove the concrete and reset the main pond liner? Do you think I should reset the entire liner? I am simply looking for some semi-professional advice as to what *I* can do to try and save it? I dont have much of a budget at this point to work on it. I and my family like it very much. I would like to restore it if at all possible. It is a nice feature to have in the yard. Also, what should I do about the fish and frogs? There are three 6-inch goldfish that my sister has become very attached too. Should I buy a cheep plastic kids pool or a small shell liner to put them in? Is that even a good idea? They are used to the pond that theyre in and I dont know if putting them in a smaller unit might shock them somehow and cause them to croak. Also there are numerous frogs which I would like to disturb as little as possible.
