The great flood of 1965 on the Mississippi River, along the eastern border if the State, exceeded any flood known in 139 years. It cause damages probably in excess of ten millions of dollars in the State of Iowa. Studied now in progress will more thoroughly cover this and other phases of the flood. The underlying cause of the flood was an abnormally cold winter which prevented the melting of an ex

The approximate area inundated near Fort Worth, Texas, by Big Fossil Creek, during the flood of September 7, 1962, is shown on a topographic map to record the flood hazard in graphic form. Big Fossil Creek, which drains an area of 74.7 square miles, flows generally southeastward along the northeast edge of Fort Worth through Richland Hills and Haltom City, into West Fork Trinity River. The flood o

The lower Mesilla Valley extends southward from the vicinity of Anthony, Tex., to the gorge of the Rio Grande north of El Paso and westward from the Franklin Mountains to the east edge of La Mesa. The increase in the use of ground water for the public water supply of El Paso and for supplemental irrigation, when the surface-water allotments were inadequate, emphasized the need for an investigation

A reconnaissance investigation of the sediment transported by selected Georgia streams during the period December 1957 to June 1959 was made to provide a general understanding of the physical quality of stream water in Georgia and to supply facts needed in planning more detailed work. The investigation was made by studying the variation of sediment concentration and sediment load with stream d

The Brazos River basin, which makes up 15 percent of the land area of Texas, extends from the High Plains, where altitudes reach 4,200 feet and the average precipitation ranges from 15 to 20 inches a year, to the Gulf of Mexico where the annual rainfall is 45-^50 inches. Large reservoirs have been built in the Brazos River basin, but the use of the stored water has been limited because the salinit
