I am very interested in your plans for the Havant Thicket reservoir and would like to suggest that, if you haven't done so already, you speak to the RSPB. The RSPB owns or manages over 200 nature reserves across the UK, and would make an ideal partner for managing a new nature reserve here. They often work in partnership with water companies and their expertise and reputation would be invaluable. As as RSPB volunteer I know first hand how good they are.
