Building a moat

I am gathering info about cultivating a moat/stream around 20 acres of land in Washington state and doing it as natural but efficient as possible. My hope is to farm fish there, use it for water power and make it possible to swim/play in some areas. What are some important factors to consider? What are some natural systems you can recommend using? What are some cost effective ways? What is a realistic timeframe? I welcome all ideas and experiences. Thank you!

That article is amusing... but not meant for serious reading imo!


By far biggest worry for me would be the departments of sadness.

In my neck of the woods, I think that to avoid them it would need to NEVER be connected to fish bearing creeks, even in winter flood.

Stocking it with anything is another point that they involve themselves with... either to license or ban depending on the species.

Using the water it contains for any commercial purpose, ie a farm that sells anything, is another.

Dams are another, engineering and permits to make aure you don't build a shitty dam that washes away an elementary school when it fails...


If you are live somewhere where the cannibal hordes have consumed the office-weasels, things get simpler..


Retention is a big concern. I have clay, but it isnt bottomless, and isnt a very predictable thickness, so the larger the work the greater the risk of delving too greedily and too deep, and losing water retention as I bust through into sand or some such. More numerous smaller ponds seem safer from this perpective..

On the other hand for storage purposes a deeper pond is preferable for temp control, evap, space required, etc... going deeper becomes a calculated gamble..

Finally, it's not that hard, if you have an excavator, to dig a lot of holes/trenches. What is hard is disposing of all the stuff you dig up! For me to dig a 14ft deep pond from ground level I end up with lots more space occupied by spoil than by pond, and taking it anywhere at all will take much more time than digging it did. And in the summer that pond will only have maybe 5ft of water in it, so going shallower isn't much of an option..


All that said... a really good contour map would be a good place to start your planning, and more info would surely spark further discussion!

Thank you! That's a lot to consider and I will keep it in mind. I am trying to wrap my mind around everything included in such a process. I will start thinking about a contour map.

BTW I dont intend to sell any of the fish directly but may cook some of the fish seasonally and sell plates. Not sure if that requires a separate license from the restaurant. I want as little gov involvement as possible but Im realizing how unrealistic that may be (SHIT!).

And by "deep enough to swim" I'm thinking 4-5 feet max. In my mind, its more like a stream with one pool section a bit deeper than the rest. Maybe if gravity is used to pull the stream down into the pool and have some system that carries the water upwards.

I realize it's one thing to have a vision of something working but another to consider what it actually takes to afford those things, which is why I'm asking for a reality check.
 
Always! Wait. Never. Shut up. Look at this tiny ad.
