The Statewide Flow Line data was developed as mandated in the Oregon Private Forest Accord (PFA), a result of negotiations between timber industry and conservationists to better protect fish habitat through increased requirements in the Oregon Forest Pracitces Act (FPA) on tree retention in riparian habitats along fish bearing streams. The Flow Line data includes a synthetic stream model for the state of Oregon, with attributes indicating fish presence, flow permanence, and many other attributes identified as required for use with FPA regulations. This information is updated regularly using surveys conducted on fish presence and flow permanence.

Initial development of these data began with using best available Digital Elevation Models (DEMs) to model a synthetic stream network. Where available, lidar DEMs were resampled to a 2 meter resolution. Where lidar was not available, the National Elevation Dataset (NED, resolution of 10 meters) was used. After streams were model the Fransen fish model (Brian R. Fransen, Steven D. Duke, L. Guy McWethy, Jason K. Walter & Robert E. Bilby. 2006. A Logistic Regression Model for Predicting the Upstream Extent of Fish Occurrence Based on Geographical Information Systems Data, North American Journal of Fisheries Management, 26:4, 960-975, DOI: 10.1577/M04-187.1) was applied to predict fish presence for all streams across Oregon. Historic ODF data (maintained in the ODF Statewide Streams Fish Presence dataset) was then conflated to the synthetic streams to overwrite the fish model outputs with any valid fish survey. These data were checked by Oregon Department of Forestry (ODF) and Oregon Department of Fish & Wildlife (ODFW) GIS staff to meet minimum conflation success rates. Errors were identified and documented for future updates.</SPAN></P><P><SPAN>The Flow Line data will be continuously updated with fish and flow permanence surveys, following established protocols and workflows developed by ODF and ODFW. Errors in conflation with historic data, and errors in geometry from the DEM modeling will also continue to be corrected. This data should be treated as a dynamic layer, with any export product frequently updated to ensure the most current information is being used.</SPAN></P></DIV></DIV></DIV>

<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>This dataset has been thoroughly reviewed to assess conflation accuracy with the previous ODF Statewide Streams data, and was found to have some conflation errors. Additionally some areas have been identified as containing errors in the DEM stream modeling.
