Clean Rivers Program Basin Reports and other Publications

The purpose of these reports are to inform the public, the stakeholders, and other agencies as to the condition of the Rio Grande basin, improvements and potential problems within the watershed, the efforts of the Texas Clean Rivers Program (CRP) and its partners to monitor and assess the waters of the basin, and potential resolutions to any negative trends within the basin.  The preparation of these reports was financed through grants from the Texas Commission on Environmental Quality. This page also contains links to administrative reports for CRP.
