Rutland Water is a Reservoir in the East Midlands
The dam was built and Rutland water was created in the 1970s.
The reservoir covers a 12 km2 area and it's filled with water from two rivers - The river Welland and the River Nene.
Rutland Water was designed to supply the East Midlands with more water - enough to cope with rapid population growth in places like Peterborough.
Areas around the reservoir are also used as a nature reserve and for recreation.
Impacts of Rutland Water:
The reservoir boosts the local economy - it's a popular tourist attraction because of the wildlife and the recreation system.
Around 6km2 of land was flooded to create the reservoir. This included farmland, so more farmers lost their livelihoods.
Lots of recreational activities take place on and around the reservoir, e.g. cycling, sailing, windsurfing.
