Here in the Alfara valley the river is thundering down into the ravine- The small baranc which goes under our driveway has water passing through which makes it look very attractive but as this comes out of the irrigation supply I suppose that it means there is a blockage somewhere which I shall have to go and relieve.

What are you proposing to use to "unblock" your obstruction Tony?????   ;)
