Had my small catfish pond dug out , removing the liner and surfaced with gumbo clay. It’s about 60 ft diameter and 6 ft deep. Been filling it for about a week got to approx 2 ft from top and it seems to have slowed to a stop for the last day. I figure it might be wicking and sealing itself. Had a huge rain at 4 ft water level created a crevice that I hoed in to fill but yesterday it seemed to not get fuller. Could this crevice be the culprit as it isn’t compacted like the rest of the pond? Clay is 18+ inches deep at walls. I stopped filling it last nite and this morning I was down 12 inches. It has slowed now to where it may be below the crevice damage. Any thoughts, solutions , need help thanks
