Description
The objective of this study is to quantify population, community, and ecosystem level changes as a result of salmon recolonization of the Cedar River, WA above Landsburg Dam. The dam was installed in 1901, blocking the upstream migration of adult salmon and steelhead from about 43 km of river habitat. A fish ladder was installed in 2003 to allow adult salmon passage. We collected baseline data on water chemistry, habitat, isotopes (periphyton, invertebrates, fish, riparian trees) and resident trout and sculpin populations in 2000-2002. These studies have been ongoing since 2000. A mark-recapture study in Rock Creek, the largest tributary available to salmon, was started in 2004 to quantify growth, movement, and survival of juvenile coho and resident trout.
Diet data from resident fish and juvenile coho.

| Cedar River Fish Diets 2000-2001 (RESTful) | Unknown | Counts of diet items identified in fish stomach samples using a compound microscope. Diet includes invertebrates (larvae or nymph; pupae; adult) and fish from the stream, and adjacent terrestrial invertebrates that fall into stream. Objective of collecting these data were to establish baseline data on resident fish diets before provision of fish passage at the dam in 2003. Fish passage was installed to allow Pacific salmon access to the watershed above the dam for the first time in 100 yrs. For details on sample collection and processing see Kiffney, P. M., C. J. Volk, and J. Hall. 2002. Community and ecosystem attributes of the Cedar River and tributaries before arrival of anadromous salmonids.
