Rugged rock walls of the Columbia River Gorge rise to 2,000 feet above the lake. Visitors can experience firsthand the operation of two of the Nation’s largest hydroelectric powerhouses and watch migrating fish traveling upstream at the underwater viewing rooms next to the fish ladders. Bonneville Lock and Dam has three recreation areas, a fishing area, fish hatchery, trails and a visitor center.

: The area receives a high amount of precipitation. Much of the precipitation comes from October to April in the form of rain at the low elevations and as wet heavy snow in the higher elevations. Winter temperatures are normally cool at the lower elevations and cold at the higher elevations. Although snow is possible in the lowest elevations, it is infrequent and does not stay on the ground for long. Late spring, summer and early autumn bring the best chance for clear, sunny days and bring moderate temperatures.

Location: Located in the Columbia Gorge National Scenic Area 40 miles east of Portland, Oregon, and Vancouver, Washington. From Portland, OR, 40 miles E on I-84. From Vancouver, WA, 40 miles E on WA 14.
