Circulars

Circulars are a short series of Texas Water Commission Reports that ran from 1962 to 1968. All available hard copies have been scanned.

• Note 1: The Drainage Area reports all include the same maps: figure 1 Principal Physiographic Provinces and figure 2 River Basins of Texas. We link to them once here, rather than adding the same maps redundantly to each report.
• Note 2: Several Circulars are old Publications lists you might find useful as a bibliographic reference. All publications mentioned are out of print and unavailable as hard copy; however, many have been digitized and made available on these TWDB Publications pages.
