This is a dredge material deposition site named the Woodland Islands. Western Fisheries Research Center scientists study this area as habitat for fish like salmon.
Amy C Hansen
Amy is a Fish Biologist in the Western Fisheries Research Center working out of the Columbia River Research Laboratory in Cook, Washington. Her research focuses on Pacific salmon, green sturgeon, dam passage and survival, and restoration monitoring in Washington, Oregon, and California.
Amy’s research focus is describing fish migration and survival of juvenile and adult Pacific salmon and green sturgeon in rivers and reservoirs throughout Washington, Oregon, and California. A combination of telemetry techniques are used at a variety of high-head and diversion dams or modified river channels to describe and understand migratory fish movements in relation to flows, seasonal and diel timing, and passage structures. Recently, Amy monitored a restoration site intended to provide new rearing habitat for juvenile Pacific salmon and other community fishes. Future monitoring will provide insights into how juvenile fish are utilizing this restored site over time, within a migration season and between years.

Study Map of Tagged Juvenile Late-Fall Run Chinook Salmon Released Upstream of Shasta Reservoir, CaliforniaStakeholder interests have spurred the reintroduction of the critically endangered populations of Chinook Salmon to tributaries upstream of Shasta Dam, in northern California. We released two groups of acoustically tagged, juvenile hatchery, late-fall Chinook Salmon to determine how juvenile salmon would distribute and survive.
