In digging my pond, I keep coming up with ideas that I think might be beneficial to my overall goal. I'm not shooting for an entirely low-maintenance pond. I'm in the area of 2500 gallons and want it to be as [Texas] natural as possible. It will be stocked with bluegill/sunfish. I've opted against a bottom drain (it just won't fit in with my plans with a submersible pump). However, since I know the benefits a bottom drain can bring, I've been thinking of ways that I can simulate some of these benefits. For the "muck" accumulation and disposal, I've thought of this: Would I be crazy if I dig a cylindric hole (maybe something the size of a 1 gallon bucket or a plastic tree/shrub planter) at the absolute deepest part of the pond and slope everything towards this? The liner will cover everything as normal (no bulkheads or cuts in it). I will then put in a physical bucket (again, like a 1 gallon bucket or a plastic tree/shrub planter). I will weigh it down with a small layer of gravel. My vision is that all the muck will find its way down to this bucket, which I can then relatively easily retrieve and clean (install some sort of handle or hooking mechanism). The submersible pump will be in close proximity to this faux settlement chamber. Getting the exact placement is going to be trial-and-error I think. The finer details I haven't thought about yet, but I wanted to run the idea past you professionals here before I really started to rack my brain on it. So what do you think?
