However, operating revenue for the company was at a deficit of £3.7 million, a result of a large cut of 16 per cent in the government grant given to BW, and through the continuing programme of renovation and works costing £92.1 million. British Waterways owned a large canalside property portfolio which made a considerable contribution to the funding of the waterway network. This amounted to £130m in the five years prior to 2008. As of 2008, a HM Treasury team was reviewing the management of this portfolio in terms of public sector savings and efficiencies. Another source of revenue contemplated by BW in October 2008 was the installation of 50 wind turbines on waterside land, generating around 100 megawatts. As part of British Waterways' commitment to promote the canals to users other than boaters, BW set up the Waterscape website in 2003 to be an official information and leisure resource for UK inland waterways. The website worked alongside the Environment Agency and the Broads Authority and covered all canals, rivers and waterways in England, Scotland and Wales. The Waterscape website was taken down on 3 July 2012 and was replaced by the new website of the Canal & River Trust. The following waterways and dockland were under British Waterways' ownership and care:  The Environment Agency is the navigation authority for the non-tidal River Thames, rivers in the Fens and East Anglia and some other waterways. The Port of London Authority is that for the tidal section of the Thames. Broads Authority is that for the Norfolk Broads. The Manchester Ship Canal, Bridgewater Canal, Basingstoke Canal, Cam and Chelmer and Blackwater Navigation were managed by other authorities.
