Neches River Basin

Left: the Neches basin (WBD HUC4 1202) with its NHDPlus HR network, its larger lakes and reservoirs, and our Upper Neches model (USGS 08032000) in orange. Right: that model drawn large, every one of its channels, with its water bodies in blue.

  • 1 published SWAT+ model
  • NHDPlus HR: 44,028 km of network flow paths in its Texas HUC8s, 2.96x NHDPlus V2.1's 14,886 km
  • 11 USGS gauges with a 90 % daily record, 2014-2024, in its Texas HUC8s (6 of 7 HUC8s covered)
  • 7 HUC8s mostly in Texas, 26,023.2 km² in all (WBD HUC12 sum)

Basin: HUC4 1202 (Neches) of the USGS Watershed Boundary Dataset.

Basin name: TWDB Major River Basins (2014). TWDB: 'These are not the official TWDB basin boundaries.'

Each point is one basin (WBD HUC4), over its HUC8s that lie mostly in Texas: its network flow paths in NHDPlus Version 2.1 (across) and in NHDPlus HR (up), filled with canals and ditches in both counts, hollow without them. On the line, the two would be equal. Ringed: the two datasets' areas for this basin differ by more than 5 %: Galveston Bay-San Jacinto, Brazos Headwaters, Lower Brazos, Upper Colorado, Lower Colorado-San Bernard Coastal, Central Texas Coastal, Rio Grande Closed Basins, Lower Pecos and Rio Grande-Falcon. In this figure, this basin's points are orange.

A model of your Texas watershed

We build a SWAT+ model for a USGS stream gauge in Texas, from national data. You download it as files you open in SWAT+ Editor and run, and you keep the files.
