The Oast House Visitor Centre is open from 11am to 4.30pm on Wednesdays, Saturdays, Sundays and Bank Holidays; April-end October. There is an Information Centre, a small shop and light refreshments. Access to the main part of the reserve is by permit and for recording and study only.
The reserve covers approximately 32 hectares. The reserve is well known as a significant staging post during the spring and autumn migrations with regular appearances from ospreys and many other long distance migrants. Most of the reserve is open water, vital for many species of wildfowl. Areas of mud, gravel and concrete are uncovered around the edges of the reservoir during summer and autumn, which supply feeding and nesting areas for waders such as lapwing and little ringed plover.
