Lee Falls, Waterfall in Washington County, Oregon

Lee Falls is a waterfall on the Tualatin River in Washington County, Oregon, pouring over a basalt rock formation beside Southwest Lee Falls Road on private timber land. It is wider than it is tall, an unusual shape for the region, and a swimming hole lies beneath the falls. Downstream are Little Lee Falls and the community of Cherry Grove; upstream is Ki-a-Kuts Falls.

The falls were named after James A. Lee, a sawmill operator who worked in the region during the 1800s. His connection to the area left this landmark bearing his name.

The falls take their name from James A. Lee, a 19th-century sawmill owner, and the surrounding timber land still carries that logging history. Southwest Lee Falls Road runs alongside the falls, and the unincorporated community of Cherry Grove lies downstream.

Lee Falls sits beside Southwest Lee Falls Road on private timber land, so access depends on the landowner's permission. The falls pour over basalt and are wider than they are tall, with a swimming hole beneath them. Little Lee Falls and the community of Cherry Grove lie downstream; Ki-a-Kuts Falls is upstream.

The falls display an unusual shape where the width of the water flow is wider than the vertical drop. This broad, shallow arrangement sets it apart from the typical steep cascades found elsewhere.
