Ecologically relevant river size classes for NHDPlus v1 flowlines in the 14 state SARP region. Size class was determined for each river flowline using the cumulative drainage area from NHDPlus v1 dataset. The data are scaled to show the largest rivers at the regional scale. Zoom into the map for smaller rivers, creeks, and headwaters. For more information about how this attribute was developed by the Southern Instream Flow Network (SIFN), go to http://www.southeastaquatics.net/sarps-programs/sifn/instream-flow-resourcesYour comments about this dataset are welcome. Please send comments to the dataset author using the Comment tab below.Â
Ecologically relevant river elevation classes for NHDPlus v1 flowlines in the 14 state SARP region. Elevation was derived from the NHDPlus v1 dataset. For more information about how this attribute was developed by the Southern Instream Flow Network (SIFN), go to http://www.southeastaquatics.net/sarps-programs/sifn/instream-flow-resourcesYour comments about this dataset are welcome. Please send comments to the dataset author using the Comment tab below.Â
River classification by months of high and low flow and range of variability.  Original gage point data was extrapolated to near by areas using the Watershed Boundary Dataset, the Baseflow Index grid, gage data, and expert review.For more information about the hydrologic classes and how this attribute was developed for the Southern Instream Flow Network (SIFN), go to attached report or visit http://www.southeastaquatics.net/sarps-programs/sifn/instream-flow-resources.  Your comments about this map and the attribute databases are welcome. Please send comments to the map author using the comment tab below.
The SARP River Classification Framework provides consistent categories of ecologically relevant attributes for streams and rivers across the region at the NHD+ segment scale. The attributes that are currently available include: 1) stream size: by basin area and mean annual flow; 2) gradient: by average segment slope; 3) EPA Level 3 Ecoregion; 4) TNC Freshwater Ecoregion; and 5) Ecological Drainage Units.  For more detailed information, go to the SIFN page on the SARP website at http://www.southeastaquatics.net/sarps-programs/sifn
Ecologically relevant river slope classes for NHDPlus v1 flowlines in the 14 state SARP region.  Slope was derived from the NHDPlus v1 dataset. For more information about how this attribute was developed by the Southern Instream Flow Network (SIFN), go to http://www.southeastaquatics.net/sarps-programs/sifn/instream-flow-resourcesYour comments about this dataset are welcome. Please send comments to the dataset author using the Comment tab below.Â
River classification by months of high and low flow and range of variability.  The flow season classes are based on a multivariate clustering analysis of monthly flows for reference USGS gages in the 14 states of the SARP region.For more information about the hydrologic classes and how this attribute was developed for the Southern Instream Flow Network (SIFN), go to http://www.southeastaquatics.net/sarps-programs/sifn/instream-flow-resources.Your comments about this data layer are welcome.  Please send comments to the map author using the Comment tab below
