Description

Abstract: This report summarizes data collected at eight LCM basins for adult salmonids (1997-2013 return years) and out-migrating juveniles (1997-2014 sample years). In addition to previously unpublished data for the 2012-2014 sample years the out-migrant estimates have been recalculated with a new estimator (Bonner and Schwarz 2011). The report is organized into chapters for each LCM site from north to south along the Oregon Coast (Figure 1). LCM sites are located on North Scappoose Creek (Columbia River), North Fork Nehalem River, East Fork Trask River (Tillamook River basin), Mill Creek (Siletz River basin), Mill Creek (Yaquina River basin), Cascade Creek (Alsea River basin), West Fork Smith River (Umpqua River basin) and Winchester Creek (Coos River basin). There are currently three additional sites monitored by the LCM project and cooperators where only out-migrant traps are present. We collect annual juvenile outmigrant estimates and associated data from these sites. They include the East Fork Lobster and upper main Lobster Creeks and Tenmile Creek. Data collection began in 1982 at the Lobster Creek sites and in 1992 Tenmile Creek. Out-migrant data was also collected at sites on the Little North Fork Wilson (1998-2013), Little South Fork Kilchis (1998-2006), upper East Fork Trask River (2007 and 2008), and Cummins Creek (1992- 2012), but these sites are no longer in operation.

Purpose: In 1997, as part of the Oregon Plan for Salmon and Watersheds, the Oregon Department of Fish and Wildlife (ODFW) began monitoring survival and migration of salmonid fishes (Onchorhynchus spp.) in selected coastal basins. The primary objectives of the Salmonid Life-Cycle Monitoring (LCM) Project are to estimate abundance of adult salmonids and downstream migrating juvenile salmonids and estimate marine and freshwater survival rates for coho salmon (Oncorhynchus kisutch). The LCM Project also collects data and calculates the coho salmon marine survival prediction for fisheries management (Suring and Lewis 2013) and has evaluated the effects of habitat modification on salmonids (Solazzi et al. 2000, Johnson et al. 2005).
