The Theale complex stretches west from the Bottom Lane floods to the east and the largest pit in the area, Theale Main Pit. This area also includes Hosehill Lake LNR which was given it's Nature reserve status in 1997 and the Wigmore Lane pits now well known for the 2007/08 Ferruginous Duck.
They are situated to the east of the M4 motorway and south of the A4 at Theale, In the east of the complex is Bottom Lane Floods, a number of flooded fields that are adjacent to the Kennet & Avon Canal. To the north of the Theale complex is the Wigmore Lane Pit's, a collection of anglers pit's that have hosted Scaup, Ferruginous Duck & Red-crested Pochard. Hosehill Lake Nature Reserve is located at Sheffield Bottom and found opposite the Fox & Hounds Pub, Sunnyside, Station Road, Theale. With a wide range of bio-diversity on the reserve it's always a special place to visit, Birds, Butterflies, Dragonflies & Insects in abundance during the Summer and large numbers of wildfowl during Winter. Finally Theale Main pit is found opposite Hosehill Lake and is the largest Gravel Pit in the Theale area, the overgrown garden at the entrance and the scrub under the pylon is always a hive of Warbler activity during summer. Passage and Winter Rarities are occasional with past sightings of Diver, Scooter, Eider, Ring-necked Duck and even Petrels.

From inside the gate you have three choices, to your right a path leads off towards the pylon where during summer Blackcap, Common & Lesser Whitethroat, Chiffchaff, Willow & Garden Warbler can all be seen and heard flitting through the scrub under and around the pylon. To your immediate left from the gate is an area of scrub known as "the garden", it is another Warbler hotspot during summer and Nightingale can often be seen and heard from this area. Continuing straight ahead will take you towards Main Pit, the path leads you round to the right where a spit gives the best views out across the pit. It's always worth checking the pylons for Peregrine as they can often be found perched up, watching the world go by.

Hosehill Lake LNR.SU648696 No9 on map

Hosehill Lake LNR is situated across the road from the Main Pit, you can park in the lay-by at the entrance to main pit or park in the small lay-by on the west side of the Nature reserve. The alternative is to park at the Fox & Hounds pub and take a stroll round the reserve followed by a refreshing beer or quick snack.
Hosehill Lake was given it's nature reserve status in 1997 by the Newbury District Council and since then the TABCG has assisted West Berkshire council with the management of this reserve. The creation of the Lake Island, Tern Rafts, Sand Martin Bank and Butterfly Meadow have all added to the diversity of wildlife that now calls this tranquil reserve home. The re-planting of Phragmites reedbeds have encouraged Reed & Sedge Warblers to take up summer residence and the occasional Bittern in winter. Nightingale can often be seen and heard during Spring as they try to attract a mate and during the summer months Hobbies are often hawking insects over the lake, there's always the chance of a "purring" Turtle Dove as well. If your an Insect lover there's plenty about during the summer months, Butterflies & Dragonflies are usually in good numbers amongst the other creepy crawlies, so there's always something to see. Improvements are always ongoing at the reserve with the help of much needed volunteer work to create the perfect spot for wildlife.
A 1 mile circular walk encompasses the Lake with interpretation boards at intervals to show what might be seen, a number of seating areas are spread out around the lake for those that want to sit back and watch what's going on. Watch the numerous nest boxes during spring for early nesting activity and don't forget to stop and watch the feeders on the west side of the reserve, Wander through the Butterfly meadow during summer whilst keeping an eye out for passing Dragonflies. Always plenty to do and see at all times of the year.
