The introduction provides a general description of the watershed in terms of its natural and human-made features, ownership and current land uses, and the communities within the watershed. Information in sections 1.2 and 1.3 was compiled from the Oregon Watershed Assessment Manual (Watershed Professionals Network, 1999), the Calapooya Creek Watershed Analysis (USDI Bureau of Land Management, 1999), and the Lower South Umpqua Watershed Analysis (USDI Bureau of Land Management, 2000). Additional information is from the following sources’ databases: The Oregon Climate Service, the US Census Bureau, and the Douglas County Assessor.The Calapooya Creek Watershed assessment has two goals: 1) To describe the past, present, and potential future conditions that affect water quality and fish habitat within the Calapooya Creek Watershed; and 2) To provide a research-based action plan that suggests voluntary activities to improve fish habitat and water quality within the watershed. The Calapooya Creek Watershed is 157,282 acres. The City of Oakland is entirely within the watershed boundary. The northwestern section of Sutherlin is also within the Calapooya Creek Watershed. The most common land use in the Calapooya Creek Watershed is forestry, with 64% of the land base used for public or private forestry. Agriculture constitutes 33% of the land use, and mostly occurs in the western half of the watershed. Land ownership is primarily private (91%), with public ownership mostly administered by the Bureau of Land Management.
