Washington Union is one of the most popular boat ramp access points in Black Hawk County, located at the confluence of the Cedar River and West Fork Cedar River.

The gravel ramp works well and can accommodate both motorized boaters and paddlers, with planned improvements including expanded parking for trailers, a tie-down lane for motorized boats, and a separate staging area for paddlers.

Note that the steep driveway has historically been in poor condition, though parking expansion and driveway reconstruction were planned as part of a 2019-2020 bridge replacement project.
