Country diary: carp find their quarry but become easy prey in the shallows

Stanhope, Weardale: A watchful heron awaits his moment as the fish introduced to this former industrial landscape gorge on a rich supply of damselfly nymphs

In the heat of yet another cloudless summer afternoon the still air in Ashes quarry wobbled in the heat haze. Blasting, hewing and hauling of limestone ended here 60 years ago. Since then nature has reclaimed this peaceful mile-long scar in the fellside; today the loudest sound came from chirruping grasshoppers.

The prolonged drought is unlikely to dry up the flooded quarry floor, an olive-green oasis surrounded by parched, yellowing grasses growing in the thin veneer of soil on rock scree. Standing on the edge of the squelchy bog, among cotton grass shedding its gossamer seeds and head-tall reed mace, I listened to the croak of moorhens hidden in channels among the forests of water horsetail, and also heard a strange plopping sound.
