Datasets created for the Border Environmental Health Initiative (BEHI) follow watershed boundaries as defined by Woodward and Durall (1996). As part of the U.S.-Mexico Border Field Coordinating Committee Issues Team, Woodward and Durall used surface-water drainage basins as the primary basis for defining and delineating the extent of the border area from a shared-water resources perspective. In order to provide integrated datasets in the border region, local and regional BEHI datasets have been clipped to this boundary.
This hydrography feature class represents a combination of US streams and Mexican streams for the U.S.-Mexico Border Environmental Health Initiative. This dataset shows low resolution streams. US streams are from the National Atlas 1:2,000,000. Mexican streams are from Instituto Nacional de Estadística Geografía e Informática (INEGI) 1:1,000,000.
