Summer is almost here, and there is much that visitors and residents can do to protect Seaside's watershed! Our water comes from the South Fork of the Necanicum, a vital salmon spawning and rearing stream. Together, we can keep our streams cold, clear, and healthy for fish and wildlife year-round. The watershed includes all of the land and tributaries contributing water to the Necanicum River as it flows from its headwaters 2,800 feet above sea level in the Coast Range to the Pacific Ocean in the City of Seaside. The birds are welcoming you to the Necanicum Estuary. Just outside the hustle and bustle of Seaside on the north end of town, the Necanicum, Neawanna and Neacoxie waterways converge. Flowing from the soaring peaks of the north Oregon Coast Range, the headwaters of the Necanicum River are located at nearly 3,000 feet, nestled between Humbug and Sugarloaf Mountain. The Necanicum River is a river on the Pacific coast of northwest Oregon in the United States, approximately 21 miles (34 km) long.
