Steven Sobieszczyk 2011 Active Channel for Fanno Creek, Oregon vector digital data http://water.usgs.gov/lookup/getspatial?fannoCk_active_chnl Fanno Creek is a tributary to the Tualatin River and flows though parts of the southwest Portland metropolitan area. The stream is heavily influenced by urban runoff and shows characteristic flashy streamflow and poor water quality commonly associated with urban streams. This data set represents the active, wetted channel as derived from light detection and ranging (LiDAR) data and aerial photographic imagery. The wetted channel boundary is equivalent to the extent of water observed during a 2-yr high flow event. This data set was developed as part of an USGS carbon study that examines sources of carbon-rich organic material along Fanno Creek. In order to quantify how much material enters the stream, the stream extent needed to first be defined.

Stream conditions vary considerably during different parts of the year. Attribute data only describes one static situation as observed in base data. Data are topologically correct in ArcGIS. Data are complete. Data set manually derived from 1-meter resolution light detection and ranging (LiDAR) data and 0.5-meter resolution aerial imagery. This mapping is a reference frame for geomorphic analyses and offers best available boundary for where water flows in Fanno Creek. All channel mapping was reviewed by another team member to ensure quality and accuracy. One reach of the river in Greenway Park was restored in the time period between the NAIP imagery (2009) and the LiDAR flight (2009). Active channel represents more recent LiDAR data and current extent. The active channel was interpreted and digitized at a scale of 1:1,000. Mapped accuracy +/- 3 meters. Watershed Sciences, Inc.

The outline was drawn to represent the active channel as seen at a scale of 1:1,000. The channel width for the active channel is roughly equivalent to where water would be present during a 2-year streamflow event. LiDAR1 LiDAR2 20101001 Digitizing: Polyline features for each bank were closed at the headwaters and confluence of Fanno Creek and Tualatin River to form a polygon feature. Polygon feature was produced using "Feature to Polygon" tool in ArcToolBox. 20101003 Digitized active channel extent was compared against NAIP aerial imagery to verify presence of water and location of stream.
