The Group operates in conjunction with CEMEX, the site owners and the Blackwater Valley Countryside Partnership both of which bring resources and expertise in active conservation within the 30 kilometres of the Blackwater Valley.

For the past 50 years or so gravel has been extracted  from the Blackwater Valley, stretching westward from Sandhurst to Eversley where it continues today. Moor Green Lakes is the result of restoration of part of that area. Land north of the river stretching for 2.5Km to the west of the Reserve, which is presently being worked, will ultimately become a major extension of the Reserve, more than trebling its size.

The existing Reserve occupies 36 hectares (90 acres) north of the River Blackwater and lies in the boroughs of Bracknell Forest and Wokingham, in Berkshire, England. It comprises three lakes: Colebrook North, Colebrook South and Grove Lake; click here for an aerial view. The main access point for the Reserve is the Car Park off Lower Sandhurst Road in Finchampstead, Wokingham. Note that this is a private Car Park and is locked at night. It is usually open from approx 08.00; the lock-up time is displayed on a notice in the Car Park. Due to recent work to improve the drainage in the area, there is no longer any roadside parking just outside the car park, however there is room for a car at the bottom end of Dell Road, just west of the car park; but please don't block the field gates. Alternative Parking is available off Mill Lane near the sailing club at Horseshoe Lake.

If visitors identify any Health and Safety issues on the Reserve, then please report them to the Site Liaison Officer - details on the Contacts page. The Reserve Map shows the features of the reserve, including location of two viewing hides for use by members of the Group. Access to the Reserve is along the footpath running south from the main Car Park, past Colebrook Lakes North and South, to meet the Blackwater Valley Path. The Colebrook Hide is on the spit between the lakes and has wheelchair access. The Blackwater Valley Path runs beside the river along the south of the Reserve. A bridge crosses the river 100m to the east of the path from the car park and leads to Yateley. A bridleway runs in parallel with the path from the car park to the river bridge.  The path from the river bridge to Mill Lane is part of the Three Castles Path, a ramblers route running between Windsor and Winchester.  The hide at Grove Lake is situated on the south-east corner and can be accessed by the footpath from either car park, being closer to the Mill Lane entrance.

The wildlife on the Reserve has been recorded and monitored by the Moor Green Lakes Group since 1993. Nationally rare plants are present on the Reserve and the site is of local importance for wintering wildfowl. Tern Island on Colebrook Lake North has hosted one of Britain's largest inland nesting colonies of Common Terns and Black-headed Gulls.
