The Neches River User Guide: http://www.tamupress.com/product/Neches-River-User-Guide,5196.aspx I don't think you can do any better than this. It is the most comprehensive guide I have found for paddling the Neches. It contains detailed maps with GPS coordinates, put-ins and take-outs, etc. It is divided into easy half-day and full-day segments.
