Description - The dam is 2,655 feet long with an effective height of 98 feet. It is located at the head of Lake West, the reservoir formed by Lower Monumental Dam. The dam is the concrete gravity type, with an earthfill right abutment embankment. It includes a navigation lock with clear dimensions of 86 by 668 feet; and an eight-bay spillway that is 512 feet long and has eight 50-foot by 60-foot tainter gates. Lake Bryan lies directly behind Little Goose Dam. It extends about 37.2 miles up the Snake River, until it reaches Lower Granite Dam. It lies at elevation 638, and has a surface area of 10,025 acres.

Recreation - Viewing salmon in the waters is an activity available at Little Goose Lock and Dam. Lake Bryan provides fishing, water sports, camping and picnicking.
Climate - The climate of Washington varies within each region. The Cascades split the state and alter the weather patterns. The mountains receive large amounts of wet, heavy snow from October through May. These peaks remain snow covered throughout the year. The terrain east of the mountains receives approximately 12 inches of rainfall per year, generally much less than west of the mountains. Since the area east of the mountains is landlocked, temperatures in this region are lower during the winter months. Frequent winds coming down from the mountains also contribute to the low temperatures of eastern Washington.
Due to the coastal geography, western Washington is primarily temperate. The proximity to the ocean stabilizes the climate, making extreme temperatures very rare. The area receives large amounts of precipitation from Pacific rain and snow storms.
Little Goose Lock and Dam is located 8 miles northeast of Starbuck. A map is availbale above on this page.
