The Necanicum Watershed's 85 square mile footprint has provided resources for humans and wildlife for thousands of years.

The Necanicum Watershed Provides:

  • Municipal water for the City of Seaside
  • Breeding, rearing, and spawning grounds for coastal coho, chinook and chum salmon, as well as steelhead and sea-run cutthroat trout
  • Natural refuge for wildlife, including Roosevelt elk, black tailed deer, beavers, river otters, red-legged frogs, and a wide range of birds, from year-round residents like great blue herons to migrating barn and tree swallows.
  • Land for Agriculture
  • Forestry lands
  • Floodplain protection for the region

Within a short 21 miles, the The Necanicum River and its tributaries run from a height of more than 2,800 feet in the Oregon Coast Range down to the Pacific Ocean. The river is a major feature of both the city of Seaside and its outlying areas. Running along the highway and through the center of town, the river's swells during high tides and heavy rainfall are highly visible.

The short, steep landscape of the upland region of the watershed allows for very little space to absorb the water critical to the survival of the resources of the region. Fortunately, the Necanicum's watershed holds many flood plains and wetlands to help capture, filter and absorb this vital resource.

The upper watershed is dominated by coniferous forests of Sitka spruce, Douglas fir and western hemlock, which help to capture and hold rainwater, keeping the landscape moist year round. Excess water runs off into the river and its tributaries.
