Fall Creek Lake, also called Fall Creek Reservoir, is a human-made lake in Lane County, Oregon. It's located about 22 miles (35 km) southeast of Eugene. The lake is formed by the Fall Creek Dam on Fall Creek.

You can find the communities of Unity and Lowell near the lake. The dam itself is 205 feet (62 m) tall. It can hold a lot of water, up to 125,000 acre-feet (154,000,000 m3). The lake has two main parts, or "arms." One arm follows Fall Creek, and the other follows Winberry Creek, which flows into the lake.

Why Was Fall Creek Lake Built?

Fall Creek Lake is one of 13 large water projects in the Willamette Valley. These projects are managed by the United States Army Corps of Engineers. The lake was finished in 1966. Its main job is to help control floods on the Willamette River.

How the Lake Helps with Floods

The Corps of Engineers keeps the lake full during spring and early summer. This is when people use it most for fun activities. But in late summer and through winter, they lower the water level. They can drop it by up to 100 feet (30 m). This creates space in the lake to store extra water. This space is very important during the rainy season. It helps prevent floods downstream. When the water is low, you might see muddy areas around the lake. This makes it harder to do some water activities.

Fun Things to Do at Fall Creek Lake

Fall Creek Lake is a great place for outdoor activities. There are many spots for day trips and camping.

Activities and Amenities

You can find picnic tables, boat ramps, and swimming areas. There are also restrooms and a fishing pier. Many people enjoy waterskiing and jet-skiing on the lake.

Getting Around the Lake

Several roads lead to different parts of the lake. Winberry Creek Road runs along the Winberry arm. Big Fall Creek Road and Peninsula Road follow the Fall Creek arm. These roads take you to various campgrounds and day-use sites. Forest Road 18 goes even further upstream along Fall Creek. It leads to more campgrounds and hiking trails in the Cascade Range.
