Abstract The concept of the IAHS Predictions in Ungauged Basins (PUB) program has been widely embraced by the Canadian water resource community because its science plan is seen by many as a useful foundation from which Canadian water science and management issues can be addressed. Water managers are keen to update their predictive tools to those that encapsulate the recent advances in hydrological science; their interest is driven by the low density of streamflow gauges and the poor understanding of the hydrological and water quality processes and regimes. An initial Canadian PUB workshop held in Yellowknife, Northwest Territories in March 2004 developed a series of recommendations for PUB in Canada. The mechanism proposed to lead to reductions in predictive uncertainty will be a nested monitoring and research basin network (MRBN) across key regions of the country with involvement from academia, government and industry.
