Record-breaking floods occurred June 27, 28, 1954, in the Devils and lower Pecos Rivers and in some tributaries to those streams, caused by heavy rainfall of June 26-28. At the time of the flood the geological Survey was not operating a gaging station in the Devils River basin or in the Pecos river basin below Girvin. Continuous records of the flow of Devils River were obtained by the Geological Survey at the station at Baker's Crossing near Juno from May 1925 to September 1949 and on the Pecos River near Sheffield from October 1921 to April 1925 and from October 1939 to September 1949. Records of the great flood flows near the mouths of the Devils and Pecos Rivers mentioned above were obtained by the International Boundary and Water Commission, United States and Mexico, at gaging stations maintained by that agency on the Devils River near Del Rio and the Pecos River near Comstock. The outstanding nature of the flood in the lower Pecos River is shown by the fact that the maximum stage reached at the Comstock gaging station was 97.8 ft on June 27, 1954, whereas the maximum stage reached at this gage between the beginning of record in 1900 and 1954 was only 38.2 ft.
