摘要: In 2007, a comprehensive long-term river restoration project was initiated on the San Joaquin River. This implemented in order to rehabilitate habitat as well reintroduces selfsustaining population of naturally reproducing Chinook salmon (Oncorhynchus Tshawytscha) (FMP, 2010). A significant problem with any reintroduction is overestimation available habitat, which can lead unrealistic goals (Geist, 2000). Currently there limited knowledge use rearing by juvenile River; due extirpation species over 60 years ago (Yoshiyama, 1996). normal wet years, rear floodplains gain weight and strength before their migration sea. However, persistent drought that has engulfed Valley lack floodplain habitat. . Therefore, we set out investigate mainstem (four locations) during 2014 season describe conditions (physical organic matter, macroinvertebrates) would encounter.
