Investigations of the fluctuations of water‐levels in observation‐wells in Virginia

An automatic water‐stage recorder has been maintained on an observation‐well in Arlington County, Virginia, about 1‐½ miles from the United States Weather Bureau, in Washington, D.C., since June, 1928, but there are a few interruptions in the record. This is a dug well, about 28 feet deep and extends through terrace deposits of gravelly silt or loam. It has not been used for water‐supply during th

A method of estimating ground-water supplies based on discharge by plants and evaporation from soil: Results of investigations in Escalante Valley, Utah

Fluctuations of water levels in wells, if critically studied, may give much information as to the occurrence, movement, and quantity of available ground water. In some localities the ground-water level has been observed to decline during the day and to rise at night, the decline beginning at about the same hour every morning and the rise at about the same hour every night. This daily decline is du

A preliminary report on the artesian water supply of Memphis, Tennessee

Memphis is located in the part of the Gulf Coastal Plain known as the Mississippi embayment. It is underlain by unconsolidated sand and clay formations of Tertiary and Cretaceous age. The Wilcox group, of Tertiary age, and the Ripley formation, of Cretaceous age, are excellent aquifers, and all the water consumed in Memphis is derived from them. The maximum pumpage from the Wilcox group was reache

A study of surface currents in Lake Michigan

Crotalaria as a cover crop is gaining attention in our country's conservation program. This genus of the legume or pulse family consists of more than 100 species. Of this number at least six are known to be very toxic to cattle, sheep, and horses. The seeds of Crotalaria spectabilis are poisonous to bob-whites. Under ordinary conditions, however, they are not eaten by the birds when there is a
