Hydrographic and Meteorological Study of the Lower Laguna Madre - Analysis of Populations of Sports and Commercial Fin-Fish and of Factors Which Affect These Populations in the Coastal Bays of Texas

Water surface temperatures were relatively low in the spring of 1964 due to abnormally low air temperatures in late February and unusually high in November and December. Two days with below freezing temperatues were recorded in February. Rainfall was 11.0 inches below normal in 1964 compared to 8.0 inches below normal in 1963. Salinities were generally higher than in 1963, but were lower in 1964 during early summer. Salinities below 40.0 ppt were recorded from the north end of the bay for the first time since August 1962.
