A little background to get this thread going;
1; Ponds lose 6" plus per month to seepage,
2; Ponds lose less than 6" per month to evaporation(SE),
3; rainfall generally exceeds evaporation(SE),
I'm considering putting in a small pond. Yet I've been overlooking the easy place to locate it. First, it has nill, 'bout a 1/2ac, watershed. (There's a creek 45' below that I can pump "some" water from.) Another thought, I can only squeak out about 8ft. of depth due to bedrock. It occurs to me that 7 to 8 foot a water may be as good as 7 to 10 foot, I'm mainly worried about a minimum level during the summer heat.
Questions:
1; Can pond liners generally prevent seepage and how necessary is a watershed, with a liner, in rainy Alabam?
2; How necessary is it to provide liner(EPDM) backing in sandy silt/sandy clay soil?
3; Wouldn't a 12" topping/backfill elminate the need to trench tuck the liner edge?
4; Do pvc liners last as long as a EPDM when using backfill?
I hope Bruce and a couple of the other experts have experience with this. I'm traveling back to Alabam this October and hope to put together a doable pond plan.
