New pond construction - attempt #3

The second pond in the North Field was designed to make up for the first pond losing most of its water due to the lining being torn - those badgers have sharp claws! To avoid using a liner I went for a clay based lining bvut the initial build didn't hold water sufficiently so a second attempt involved lots and lots of clay. This also didn't do the trick with the suspicion that it was leaking slowly out of the uphill bank of the pond. So attampt number 3 is to dig out most of the clay, lay a pond underlay (double thickness), then a puncture resistant liner, then clay on that. Also I now have a feed from the roof of the woodshed to provide enough water in the summer. So far its working although there is still some tidying up to do. It will hopefully provode a suitable habitat for tadpoles next year and also of course newts and dragonflies.
