(who now joined the BWB) had argued that the canals should be run by a trust such as the National Trust, but the new body faced the same commercial pressures as its predecessors. The Transport Act 1968 showed a new commitment to amenity use, but waterways were put into three classes: commercial, cruising and remainder. One casualty of this was the Kennet and Avon which has never been lifted out of the bottom category for which only essential maintenance was available. The act also removed the statutory right of navigation for these canals. The period of the 70s and 80s are characterised as "three steps forward, two steps back" by David Blagrove. The restorations and growth in the leisure boat industry were offset by multitudes of other problems with closures of canals, tunnel failures and the breakdown of the Anderton lift. However the attitude of BWB gradually changed from scepticism to a more friendly attitude to the organisation. The completion of the restored Kennet and Avon Canal in 1990 and the availability of lottery funding from 1994 opened up new possibilities. The membership, which had steadily expanded during the previous decades, settled at around 20,000 and the attendance at the annual rallies and festivals kept their popularity. Organisation and governance IWA is organised into regions, each of which consist of several branches. The regions are: East Midlands, Eastern, London, North East & Yorkshire, North West & North Wales, South East, South West & South Wales, and West Midlands. The association is governed by a board of trustees. There are a number of national committees, each reporting to the board of trustees. For each committee there is an agreed role and operating arrangements, with areas of delegated responsibility. The current national committees are Finance Committee, Navigation Committee, Waterway Recovery Group, Marketing Committee, Remuneration Committee, Awards Panel. IWA's Restoration Hub supports, enables and champions waterway restoration. The current national chair is Les Etheridge, and the national deputy-chairs are Nick Dybeck and Sue O’Hare.
