About the reserve
The reservoir was created in 1965 to provide people with drinking water and was immediately colonised by wildlife. The nature reserve surrounds the western side of the reservoir and contains ancient and plantation woodlands, grasslands and wetland habitats such as reedbeds, willow and open water. Grafham Water is one of the prime bird watching sites in the county, with rarer visitors such as osprey and the occasional Slavonian grebe, alongside the more familiar resident mallards and greylag geese. With nine miles of shoreline, and around 170 species of bird recorded each year, there is always something to see.
