The Zigzag River is a tributary, about 12 miles (19 km) long, of the Sandy River in the U.S. state of Oregon. The Zigzag and one of its major tributaries, the Little Zigzag River, drain the Zigzag Glacier on Mount Hood, a high volcanic peak in the Cascade Range. Their waters flow westward to meet the Sandy River near the community of Zigzag. The river's flow ranges from 200 to 1,000 cubic feet per second (5.7 to 28.3 m3/s). Although the Zigzag River is closed to salmon and steelhead fishing, it offers catch-and-release fishing for coastal cutthroat trout.
