The catch-basin cinderblocks collapsed under the onslaught of water from the overnight storm as runoff poured down off the fields all around, and especially from my neighbors overflowing pond. However the channel I had dug a couple years ago directed all the excess water back into the “Dry Creek Bed” lined with rocks, and away to the other side of the fence-line. I plan to rebuild the catch-basin with larger and heavier terrace blocks in the Spring that will hopefully resist the water pressure, and if not that at least make the next breech more dramatic.
Merry Christmas everyone!!
