Lake 79 at Cotswold Water Park, On my map this is still a working pit and it's is still largely empty. When finished it will be one of the largest lakes, much deeper than the current trickle.
Overview
Nearly a century of gravel extraction has resulted in a series of more than 100 lakes on the borders of Gloucestershire and Wiltshire in the upper reaches of the Thames Valley.
Although the area is heavily used for recreation and by water sports enthusiasts in particular, it is also an excellent birding locality with good numbers of wintering waterfowl. In addition, the area lies on a migration flight path, the Thames corridor, and a wide range of migrants are attracted to the many waters. There are birds of interest throughout the year and there are now several nature reserves in the area.
As the pits have flooded and matured they have developed a good aquatic flora and the banks of the older pits now have extensive cover. In addition there are fields that are sometimes flooded and have water-filled ditches, hedgerows and small woodland patches in the area thus adding further habitat types.
The park has two main groups of lakes with around 70 at the western end in the Gloucestershire-Wiltshire border and more than 30 about 11km to the east entirely within Wiltshire. More than 200 bird species have been recorded in the area and many of the lakes can be viewed from surrounding footpaths and roads.
Birds
Notable Species
The Cotswold Water Park holds most ornithological interest during the winter months and numbers of Common Pochard and Eurasian Coot are particularly good with Eurasian Wigeon, Common Teal, Mallard and Tufted Duck also well represented. Also present in winter are Gadwall, Northern Pintail and Northern Shoveler, Common Goldeneye, Goosander and Ruddy Duck.
Grey Heron, Great Cormorant and Water Rail are present all year but tend to occur in greater numbers in winter and Great Bittern has become more regular in recent years. In severe winters the lakes may be visited by Smew or a seaduck, the scarcer grebes and even the occasional diver. Flocks of Greater White-fronted Goose and Bewick's Swan may also appear in hard weather. Lesser Redpoll and Siskin can often be seen in alders along the river and winter thrushes occur in good numbers. Peregrine Falcon is becoming increasingly regular out of the breeding season.
Passage periods bring terns, including Common Tern and regular Black Tern and a good selection of waders including Ruff, Greenshank and Green Sandpiper and Common Sandpiper. Scarcer migrants include regular Garganey in spring and Little Stint, Spotted Redshank, Wood Sandpiper and Curlew Sandpiper in autumn. Little Egret has become more regular in recent years. Migrant passerines include Whinchat, Northern Wheatear and Yellow Wagtail, various warblers, flycatchers and chats.
The less disturbed parts of this area are becoming increasingly important for breeding birds with both Little Grebe and Great Crested Grebe, as well as a few waterfowl including Mallard, Tufted Duck and feral Canada Goose and Greylag Goose. Also breeding ferally are a few Red-crested Pochard.
Waders such as Northern Lapwing and Common Redshank, Ringed Plover and Little Ringed Plover also nested in small numbers and Eurasian Curlew has bred in flooded fields.
Reed Warbler and Sedge Warbler nest where reedbeds are established and in local scrub and woodland there are various other warblers such as both Common Whitethroat, and Lesser Whitethroat. Blackcap and Garden Warbler, Willow Warbler and Common Chiffchaff.
Tawny Owl, Great Spotted Woodpecker and Common Cuckoo breed in the area and raptors present in summer include Common Kestrel, Eurasian Sparrowhawk and Northern Hobby.
Common Dipper and Grey Wagtail can be seen on nearby streams.
Rarities
Rarities have frequently appeared at the Cotswold Water Park and have included Pied-billed Grebe, Blue-winged Teal, Squacco Heron and Black-crowned Night Heron and Eurasian Spoonbill, Red-footed Falcon, Gull-billed Tern and White-winged Tern, Kentish Plover, Alpine Swift and European Bee-eater. In March 2003 a Kumlien's Gull was recorded.

Areas of Interest
To the east one of the better areas is Whelford Pools, a reserve of the Gloucestershire Wildlife Trust, near Fairford and reached on the minor road to Whelford off the A417 east of Cirencester.
There are two hides overlooking one small and two larger pits where waterfowl can be seen in winter and Common Kingfisher nests. This area is also of interest to entomologists with 11 species of dragonfly and damselfly to be seen including the large Emperor Dragonfly Anax imperator and the rather local Red-eyed Damselfly Erythromma najas.
Access and Facilities
Although many of the lakes throughout the area can be good for birds the best are generally at the western end. A network of public footpaths covers much of the area and Lake 34 in Keynes Country Park has a wheelchair-accessible hide with leaflets and a useful logbook detailing the latest sightings.
The walk around this area, beginning at the nature reserve car-park at Spratsgate Lane, off Spine Road, usually produces a good range of the birds to be seen and nearby Lake 77 is good for passage waders. The western lakes of the park can be reached off the A419 Swindon to Cirencester road.
Nearby Sites
Coke's Pit is another Gloucestershire Wildlife Trust reserve with wintering waterfowl including Red-crested Pochard as is the Edward Richardson reserve. This small reserve has two pits and a nature trail with a hide and can be reached from Lechlade taking the A361 northwards for 0.8km then turning left for Rough Grounds Farm.
