There are 15 major river basins and 8 coastal river basins within the state.<\/SPAN><\/P>

Each polygon is categorized as either 0 for \u201cLAND\u201d or 1 for \u201cBAY\u201d using the \u201cBAYS\u201d column in the attribute table.<\/SPAN><\/P>

Major Basin boundaries along the state line were edited to align with the state boundary layer (current as of 07/03/2019) to correct for sliver and gaps. This version represents major basins from the TWDB_MajorBasins_07032019 file edited to reflect the detailed coastline along the Gulf Coast in the TWDB_Counties_Detailed_07032019 file.<\/SPAN><\/P>

Edits made in the TWDB_MajorBasins_08072023 file include: fixing small overlaps and gaps between basins, adding topology rules, combining the detailed and non-detailed Major Basins datasets into one dataset, and adding a new \"Bay\" column with 2 polygon types: 1 for \"Bay\" and 0 for \"Land\" (tmc)<\/SPAN><\/P><\/DIV><\/DIV><\/DIV>", "licenseInfo": "
