The Netherlands is a highly populated small country with water. Water management often means a very precarious balance between fisheries, recreational activities, nature, and transportation. Water management is done by national and regional waterboards. Management of accurate, reliable, complete, and easily accessible water information was often a problem. This information was often analogous, managed by several departments, incomplete, etc. In 1997 five waterboards collaborated to make a product for management of water information. In 1998 the result was INTWIS, an Integrated Waterboard Information System. INTWIS is based on ArcGIS 8 with an Oracle database. It consists of a basic module for INTWIS management and, by now, thirteen water management supporting modules. Each of these modules has specific functionality and can be integrated with (inter)national coordinating information systems. By now, sixty-six percent of the waterboards are using INTWIS.
