Rutland Water

Rutland Water is a reservoir in Rutland, England, east of Rutland's county town, Oakham. It is filled by pumping from the River Nene and River Welland, and provides water to the East Midlands. By surface area it is the largest reservoir in England, but its capacity is exceeded by that of Kielder Water in Northumberland. Its maximum depth is 33m.

Set in 3,100 acres of countryside, it has a 23-mile perimeter track, for walking or cycling. Since the water is drawn upon when needed, the relative areas of land and water vary a little, but the flatter parts of the lake margin are enclosed by banks so that the wetland nature reserve is maintained.
