George Wilkinson visits Barmby on the Marsh, where the Ouse and Derwent meet.

Barmby on the Marsh is a small village tucked in wedge of land where the rivers Ouse and Derwent meet and continue as the Ouse and then the Humber. There are no road bridges nearby, one has to approach the marsh from the east, it is quiet and quite cut off.

We arrived when the sun was almost at its highest, on the day before the weather built to record temperatures, then broke. So we felt a bit barmy on a march.

Luckily the facilities at the Barmby Tidal Barrage Amenity Site are very good, a car park, loos, and a shady lawn with picnic tables. We jettisoned all unnecessary gear, even the emergency survival bag, and we loaded up with sun cream, soaked our hats, filled our bottles, donned our shades and wandered down to the barrage.

The place was deserted except for Dennis Garner, the controller, who looks after the mechanism that keeps the polluted Ouse out of the clean Derwent. He told us that it was the wrong season for the birds.

We set off along the top of the smooth, grassed floodbanks. The Derwent was clear, fish at least looked plentiful, a shoal of four-inch, handfuls of fingerlings and many darting fry.

Two fishermen hunted them from under large green umbrellas and swallows and dragonflies competed for flying insects. A little wooden boat chugged by. The flood banking is high, so the views are long, over the river and the cornfields to a slim steeple in Hemingbrough.

Just before a reservoir we turned inland, dropped to the low-lying fields and took farm tracks. The verges were terrific, wildlife corridors with drainage ditches alongside and the air was thick with thistle seeds many of which drifted up like fluffy snow in the lee of the hedges. A cruel sun beat down on an underdressed party of labourers who were cutting iceberg lettuces and passing them into a mobile yellow packing shed.

This area, Barmby Marsh, could be a skating rink in winter before the barrage was installed. We were overheating and removed anything that did not prejudice decency (this is not the place for the topical and foolish naked walking). Shade was rare and lingered in.

The River Ouse is unlike the Derwent, much wider, perhaps a hundred yards, and was muddy with a surge of tide. From its flood banks we got a fabulous view along the river to the Drax Power Station, its cooling towers breathing out heat for the air-con and silhouetted by the bright bleached sky. A couple of canal boats rode the flow, then a flotilla of fast gin palaces powered by. A heron stood in a barley field, and a farmer collected up giant bales of straw.

Back at the barrage we had a peer from the bird hide, out over part of the internationally-important Lower Derwent wetland site. There were no birds, except on the posters in the hide.
