Description - Dworshak Dam and Reservoir is a flood control project, completed in 1973, after seven years of construction. Congress authorized the 327 million dollar project for flood control, hydropower generation, outdoor recreation, and fish and wildlife benefits.
- At a height of 717 ft, Dworshak Dam and Reservoir is one of the highest dams in the U.S., as well as one of the most dramatic in appearance. Lewis and Clark camped in this area in 1805. The Dworshak National Fish Hatchery is the largest steelhead trout hatchery in the world.
Recreation - Fishing for kokanee salmon and rainbow trout is available at Dworshak Dam and Reservoir. Camping, hunting and hiking are also available.
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.
