FORESTRY AND IRRIGATION 



August 



on the ' ' Geology and Underground 

 Waters of the Region North of the 

 Black Hills. ' ' Later in the season fur- 

 ther work will be done in the Arkansas 

 Valley, in southeastern Colorado, to 

 complete the data for a report on that 

 important artesian district. Visits will 

 be made to a number of dam-sites in 

 various portions of the West for the 

 purpose of ascertaining the geological 

 conditions in each locality. Investiga- 

 tions of special problems of underground 

 waters will be made in Nevada, Idaho, 

 Arizona, and New Mexico. 



Investigations of the underground 

 water resources and geology of south- 

 ern California will continue under the 

 direction of Mr. C. W. Mendenhall. 

 Much of his attention during the early 

 part of the season will be devoted to 

 the preparation of reports and maps for 

 publication. 



Mr. C. E. Siebenthal, assistant geol- 

 ogist, has been directed to continue his 

 examination of the San Luis artesian 

 basin, Colorado. When that work is 

 completed, he will investigate the pros- 

 pects for artesian wells in the Uncom- 

 pahgre Valley, and at the end of the 

 season will examine the prospects for 

 obtaining deep-seated waters in the area 

 at Denver, which has not so far been 

 fully explored by deep wells. 



Mr. C. A. Fisher will continue his 

 studies of the geology and underground 

 water resources of the Bighorn basin, 

 in northern Wyoming. He will also 

 examine the coal deposits and deter- 

 mine the prospects for oil and gas in 

 that region. 



Mr. G. B. Richardson has been as- 

 signed to a study of artesian problems 

 in the eastern part of the Salt Lake 

 basin, in Utah. In this region numer- 

 ous wells are found, but the under- 

 ground waters present many variations 

 in conditions of occurrence. During 

 the first part of the season Mr. Rich- 

 ardson will finish his w r ork on the geol- 

 ogy and waters of El Paso, Texas, 

 with the view of completing a geologic 

 folio on the El Paso quadrangle. 



Mr. Willis T. Lee will make a recon- 

 naissance of Owens Valley, California, 

 where it is believed the underground 

 water conditions are similar to those 



in some of the valleys in southwestern 

 California and south-central Arizona. 

 Later in the season Mr. Lee will con- 

 tinue his observations in the Gila Val- 

 ley, Arizona, with a view to ascertaining 

 the extent of the area in which under- 

 ground waters are available, their vol- 

 ume, and the best means of utilizing 

 them for irrigation. 



Hydrographic The hydrographic work 

 Work in East, in the New England 

 States, which has been 

 organized and carried on under the di- 

 rection of Mr. N. C. Grover, of the 

 United States Geological Survey, was 

 transferred to H. K. Barrows on July i. 

 The following number of stations are 

 being maintained in this district: Maine, 

 18 ; New Hampshire, 12; Vermont, 3; 

 Massachusetts, 3; Rhode Island, i,and 

 Connecticut, i. 



A systematic study is being made of 

 the developed and undeveloped water 

 power in Massachusetts, Connecticut, 

 and Rhode Island, and other gaging 

 stations will be established in these states 

 at an early date. 



In Maine profiles are being made of 

 the lower portions of the Penobscot and 

 Kennebec rivers. In connection with 

 these profiles surveys are being made of 

 those portions of the rivers which are 

 well adapted to the purposes of the 

 Survey. 



Mr. N. C. Grover, who for the past 

 two years has carried on the hydro- 

 graphic work in New England, has been 

 transferred to the Washington office, 

 where he will direct similar work in 

 New Jersey, Pennsylvania, Maryland, 

 Virginia, and West Virginia. A care- 

 ful reconnaissance is being made in these 

 states, and the work will be extended 

 into new localities during the coming 

 season. 



In the Southern States Mr. M. R. Hall 

 is maintaining 2 stations in Alabama, 

 24 in Georgia, 3 in Mississippi, 5 in 

 South Carolina, 12 in North Carolina, 

 and 10 in Tennessee. Of these stations 

 several have been established during the 

 present season, and special efforts are 

 being made to investigate localities of 

 undeveloped water power.
