Port

The Port of Clarkston is home to one of the largest cranes on a navigable waterway east of Portland. Agriculture is a major industry in the area and the port handles a lot of barge traffic carrying grains. The paper company Clearwater Paper Corporation transports wood chips and sawdust via barges for use at a Lewiston manufacturing plant. Due to its inland location on the Snake River, the port handles goods headed out to Portland-Vancouver, and inland to distributors upstream.

The port's marina has accommodations for personal boats and yachts, many of which travel through the nearby Hells Canyon.
