Description: Tide gate inventory showing locations of known and possible tide gates from existing data sources. Data from the following sources were incorporated into this inventory: Coos Watershed Association, Coquille Watershed Association, The Lower Columbia Estuary Partnership, Oregon Coastal Management Program (Department of Land Conservation and Development) (2011), Nehalem Marine Tillamook Inventory (2001), Umqua & Smith River Estuary Restoration - Tidegate Technical Group, Tillamook Bay National Estuary Project Reconnaissance Survey of Tide Gates in Tillamook Bay Vicinity (1997), and the Oregon Fish Passage Barriers Dataset (Oregon Department of Fish and Wildlife) (2017). Duplicates were removed, retaining points from the local inventories over the statewide data sources where possible, and locations were manually corrected. Additionally, probable tidegates were identified using 2018 aerial imagery and other supporting data layers by the Institute for Natural Resources and were added to the inventory.<br><br>(Oregon Tide Gate Parternship, 2019)
