The U.S. Geological Survey (USGS) Watershed Boundary Dataset (WBD) is a national hydrologic unit (HU) geospatial dataset that defines surface drainage areas for the United States. This dataset provides a foundation for local, regional, and national applications to manage, archive, exchange, and analyze data by HU.

The new Great Salt Lake breach was opened on Dec. 1 by the Union Pacific Railroad Company. This created a new opening between the north and the south arm of the lake, allowing water to flow between the two sides. This time-lapse video shows the breach opening, which took about two hours.
