An annual report for the 2003 RNSP Redwood Creek Summer Steelhead Trout Survey and for the 2003 RNSP Smith River Summer Steelhead Trout Survey. Redwood Creek was surveyed during July and August 2003. Excerpt: "Year 2003 was the 23rd consecutive summer steelhead trout survey of Redwood Creek, the first was 1981. Six adult summer steelhead (steelhead >16.5 inches), three 'half-pounder' steelhead (smaller immature sea-run steelhead returning after less than one year in the ocean), and 63 coastal cutthroat trout (O. clarki) (cutthroat >10 inches) were observed in a mainstem survey reach. The survey reach begins on Simpson Timber Company lands and progresses downstream through Redwood National and State Parks land. Four of the six summer steelhead were within the index reach. The number of adult steelhead within the index reach has declined over time. Steelhead within the Northern California coastal steelhead ESU (evolutionary significant unit), which includes Redwood Creek, were federally listed by the National Marine Fisheries Service as threatened in June 2000." Includes a map with locations of steelhead observed. Smith River was surveyed on August 20, 2003. While other fish species were recorded, no adult summer steelhead were observed during the Smith River survey.
