GIS Applications and Decision Support Technology

• Seasonal habitat use and movements of white sturgeons
• Vertical distribution of outmigrating juvenile salmon and steelhead
• Using 2-dimensional hydraulic modeling to estimate the spatial distribution of riverine habitats
• Development of a decision support system for John Day Reservoir
• Migratory behavior of endangered Lost River and shortnose suckers during the spawning season
• Habitat use by endangered Lost River and shortnose suckers
• Using fixed-station and mobile telemetry to evaluate juvenile salmonid by-pass facilities at dams
• Determining migration paths of juvenile salmonids through reservoirs using hydroacoustics
• Using the Global Positioning System to map sampling efforts and fish distributions
• Evaluation of the effect of water management on fall chinook spawning and rearing habitat, and on stranding of juvenile fall chinook in the Hanford Reach of the Columbia River
