Introduction 1.0 INTRODUCTION Primary Author Norm Smith Secondary Author Jennifer Wright Contributor Felix Barbetti Preamble Interest in the Grand River watershed and in the fish resource found therein is increasing. The recent designation of the Grand as a “Heritage River” has heightened interest in the watershed as a whole as have earlier media articles, which extolled the fishing opportunities on this river. An article that appeared in an Ontario outdoors magazine called the Grand River fishery, “A Waiting Giant” (Ontario Out of Doors 1984) increased interest in the watershed and in its fisheries. This led to the development of plans to help ensure that the watershed and all its attributes are managed properly. The Grand River Fisheries Management Plan was completed in 1998 - a fisheries plan developed through a community-based process within a watershed context. 1.1 Purpose of the Document The Grand River Fisheries Management Plan (GRFMP) has elicited a great deal of interest since its completion in 1998. Other communities and watershed associations have expressed an interest in learning how the GRFMP was developed, the processes used and the technical information applied. In order to provide sound supporting documentation to the GRFMP, the technical background report for the GRFMP must be completed. The GRFMP was completed in 1998 with very limited resources that forced the committee to focus on the final plan and leave documentation to a later date. This background document provides the foundation, rationale and science behind the decisions made by the Grand River Fisheries Management Plan Implementation Committee (GRFMPIC). It also provides the GRFMPIC the tools to evaluate the implementation of the Plan in the future and for others to apply the process if they so choose.
