Survey water-supply papers entitled "Surface 
Water Supply of the United States." Through 
30 September 1960, these water-supply papers 
were in an annual series and then in a 5-year 
series for 1961-65 and 1966-70. Records of 
chemical quality, water temperatures, and sus-— 
pended sediments were published from 1941 to

entitled "Quality of Surface Waters of the 
United States.'"" Records of ground-water levels 
were published from 1935 to 1974 in a series of
