Abstract
Many of Oregon's salmon, the cultural icon of the region, are imperil. Salmon runs ranging from the Snake River to the Oregon coast, from chinook to coho to steelhead to cut-throat are being protected or candidates for protection under the federal Endangered Species Act of 1973. As Oregon's salmon decline natural resource agencies, such as Oregon Department of Fish and Wildlife (ODFW), are seeing substantial funding cutbacks. In order to compensate for lost personnel and rising work-loads, ODFW is increasingly turning to new technologies, such as Geographic Information Systems (GIS). This thesis describes the creation of a dynamic segmentation GIS system at ODFW and how dynamic segmentation can improve information management for aquatic resources within ODFW and across agency boundaries. Through custom programs, a linear referencing system was created, allowing non-GIS stream data to be linked to GIS representations of streams by using the milepoint of where the data occurred in a stream and what stream it occurred on. The dynamic segmentation data model allows salmon managers access to ODFW's institutional database in a new graphic way, provides a more robust set of analytical tools for habitat analysis, and enables ODFW to share databases with other resource management agencies using the system easily.
