As the SEAK Hydro database evolves, so to will the metadata for this dataset. Until noted otherwise, please reference this dataset's metadata for an older version of the source data.This map service contains two barrier layers, one from the USFS and one from the AWC. The USFS barriers layer contains points representing bedrock waterfalls in Southeast Alaska that are potential barriers to fish passage on the Tongass National Forest. Waterfalls less than 1 meter are not mapped nor are those caused only by wood or debris jams. Channel types considered to be de facto barriers to fish passage HC5, HC6, & MC3 (Channel Type Users Guide, USFS 1992) were not included in the layer. The AWC layer is undocumented at this time.
A subset of the wanter falls from an automated inventory of the names and locations of physical and cultural geographic features located throughout the United States.

Barriers to upstream fish movement (either long-term geologic, natural short-term, or anthropogenic barriers) will be used to assess whether individual stream segments are currently occupied by bull trout, for assessing risk of genetic introgression or disease to existing bull trout populations, or whether existing subpopulations are connected with other subpopulations. Only those barriers that are believed to have a significant influence bull trout distribution or population integrity will be identified.
This GeoJSON dataset contains information about 10780 waterfall and 1080 rapid locations (referred to as falls throughout the metadata) and characteristics (e.g. type and height) for the conterminous United States. This dataset centralizes known information about falls while providing basic quality control (i.e. resolving duplicate records and spatial accuracy checks) and linkages to stream networks intended to facilitate stream network analyses. Locations of falls were sourced from the World Waterfall Database (WWD, www.worldwaterfalldatabase.com), the US Forest Service Center for Aquatic Technology Transfer (acquired from Southeast Aquatic Barrier Inventory), and Geographic Names Information System (GNIS, https://geonames.usgs.gov)....
A new and more complete version of this dataset can be found at https://doi.org/10.5066/P9QQTKA0. This dataset contains information about waterfall location and characteristics. It also provides a linear reference to two National Hydrography Datasets. This dataset is based off the World Waterfall Database (WWD) and other source datasets. The coordinates and spatial attributes from the WWD were used to help verify locations in Google Earth. From there, the USGS HydroLink Tool was used to link data to both the NHDPlusV2.1 (1:100,000 scale) and NHD High Resolution Dataset (1:24,000 scale). This dataset currently includes waterfalls from the states of Indiana, Wisconsin, Michigan, Nebraska, Illinois and Missouri....
