You’ll notice the water start to cloud and get a bit green especially if the ducks are in most of the day, but just how gross it gets depends on rain, your soil, and how much you’re swapping out. With 10 ducks, you’ll probably want to move some water out every week or two in the warm months, more often if we get a heat wave or less rain.
The pond that I dug (in sand) contains about 7-8000 gallons but I won't put ducks in it this year. I did 2 years ago, and yes, 15 ducks can get it pretty messy. The main reason I don't have ducks this year is that I'm going to have a knee replacement, and already, hubby is grumbling about having to take care of the chickens when I'm out of commission.
Well, that and plucking these critters. I bought a bunch of suckers and other minnows this time, and I'm raising watercress. At the end of the season, I plan to pull all the fish and dry them for chicken feed. (Our winters are long in Wisconsin, and I can't justify pumping water through the filters and changing the water in the cold... Nope)
Because I'm in sand, I put a liner in it but I didn't want to shell for an EPDM so I got the thickest tarp that I could get, and I must say, (Cross my fingers and knock on wood), so far, it's holding. No leaks!)
What I built to save myself a bit of work and sheltering the ducks from predators at the same time is a 6 ft wide roof on the 2 long sides of the pond, angled to collect all of the rain water in the pond. (I was inspired in that by the Roman rooves slanted inward in a patio on all 4 sides)
These 2 rooves are very efficient: They each measure 20 ft by 6ft, for a total surface of 240 square feet.
According to the formula I found, a 240 square feet on which only 1" of rain falls will get me...149.61 gallons.
So yes, I'll still have to pump water from my well to fill it up. We average 40-60" of rain a year, so (4,488.31gallons to 8,976.62 gallons total for the year) Of course, you don't quite get that much because of evaporation, but it is not negligible either... The ducks will get shelter, maybe lay eggs under the rooves, or in the cabin I built for them. (The cabin was for when they were too young to go in the pond.)
That pond is in the center of my orchard as I had the same thought you did: The partial changes of water once every 2 weeks work out quite well. (I pull out only half of the water each time to not kill the fish. (These little buggers are really tough: Koi fish just could not make it. I would love to raise grass carp, but it is illegal here, so I'm screwed.)
I operate 2 sump pumps simultaneously, that I have in 55 gallon barrels to keep them a bit cleaner so the change happens pretty fast: I didn't time myself, but I can partially empty and then fill it all back up again in an afternoon. I can walk away and check on the progress every hour.
Since you are raising some ducks, and I heard that in Laos, they eat a lot of ducks, have they found a way to pluck them clean pretty fast?
I love ducks and would much prefer to raise ducks: They don't tear everything in the garden and they stay pretty much together, but plucking them!!!...
