River corridors are of immense importance and increasingly coming under pressure for both in-stream and withdrawal uses. The dynamic character of these resources and the complex property regimes in which they are held present considerable challenges to resource managers. Co-management is a novel approach for manaing river resources, consistent with the movement toward decentralized planning and a particular variant of collaboration. A case study of developing co-management in a Canadian river corridor is presented. Inductive analysis from the case study illuminates processes embedded within the phenomena and leads to the construction of a synthetic model of the comanagement process. Undercurrents emerging throughout the analysis (communicative planing, social learning and adaptive management) and aspects requiring future research are reflected upon in the conclusion.
