We went to visit friends in Greetham, Rutland. On Friday morning, they took us for a walk at Rutland Water. This is the largest reservoir in England and was flooded in 1976 to provide drinking water for East Anglia and water for the steel plant at Corby in Northamptonshire. The steel plant was built after the war and closed in the 80s. The reservoir is large - perhaps 5 miles x 1 miles. Very good for sailing. There's a very nice 27 mile trail around the reservoir. We walked a 3 or 4 mile loop from the picturesque village of Hambleton.
