Scope and Content Note
The Tideland Ownership Maps of the Oregon Coast are comprised of detailed maps of the ownership of 16 tideland areas on the Oregon coast. The collection includes maps for Alsea Bay, the Necanicum and Nehalem Rivers, Nestucca and Netarts Bays, the Salmon River, Sand Lake, Siletz Bay, the Siuslaw River, and Tillamook and Yaquina Bays on the north Oregon Coast. Maps for the Chetco River; Coos Bay; and the Coquille, Rogue, and Umpqua Rivers on the southern Oregon coast are also included.
Three categories of ownership are depicted on the maps: State of Oregon lands; private lands; and port, county, federal or city lands (as one category). Each map indicates the quadrangle on which it was based and the date that the map was verified through aerial photography. Most of the maps are at a scale of 1 inch = 1000 feet; the remainder have a scale of 1 inch = 2000 feet. In addition to ownership, the maps provide details on the tidal waters, including the location of the head of tide for each drainage; airstrips, boat launches and landings, and parks; creeks, sloughs, marshes, and non-tidal streams; major roads and streets; and nearby towns.
