A bull sea lion shows a brand burned into its hide by the Oregon Department of Fish and Wildlife, to monitor it from season to season as it travels between California, Oregon and Washington. Some California sea lions, such as this one C-704, prey upon migrating salmon that gather in the downstream waters and fish ladders of Bonneville Dam on the Columbia River. The "C" in its brand denotes Columbia River. These sea lions also form bachelor colonies that haul out on public docks in Astoria's East Mooring Basin and elsewhere, where they can damage or even sink docks, Zalophus californianus

Bonneville Lock and Dam consists of several dam structures that together complete a span of the Columbia River between the US states of Oregon and Washington. The dam is located 40 miles east of Portland, Oregon, in the Columbia River Gorge. The primary functions of Bonneville Lock and Dam are those of electrical power generation and river navigation, Bonneville Dam and Locks
