So, here's the pond yesterday. It's been raining, mostly drizzling really, off and on since yesterday morning, and the bottom of the pond at least seems to be really holding its water. Even the deep hole I dug for clay is holding water at the bottom and has been for over a month, since the last rains... The second pictures shows the biological filter where the grey water enters the bathtub where Pistia stratiodes Thalia dealbata, Eichhornia crassipes and Cyperus papyrus grow in charcoal, gravel and some clay.
