Black water in pond - 10/31/19 04:54 PM

My pond is going on 6 years old, half-acre, total clay. Here in Michigan we have had a very wet fall, pond is overflowing as I type this. But this is the first year I have noticed the water look more of a black color than usual milk chocolate color. Anyone have a reason for this? Thanks!

Mine turned black from Oak Tannin

Our stream turns coffee color from leaves this time of year.

Thanks for the input, maybe it is just the age of my pond now getting a bit older and having the leaves build up more. I will keep an eye on the water chemistry and see what the future brings!

Mine is reasonably brownish from oak tannin, got caught with a lot of oak treetops in the pool area, pond filled up faster then planned.

When I pushed some, actually a lot, of green oaks into mine prior to filling, it killed everything I stocked. I had to pump it dry and let Texas summer heat dry everything out and hope for rain.

Maybe not related, but silver maple leaves are leaving a black stain on my new concrete driveway after a rain, with black streaks running downhill.
