Abstract: This report presents the results of the Roach Lake Basin, Nevada, orientation study in the Kingman 10 x 2* quadrangle of the National Topographic Map Series (NTMS). Wet, dry, and playa sediment samples were collected throughout the 420 km2 semi-arid, closed basin. Water samples were collected at the few available wells and springs. In addition to neutron activation analysis for uranium and 15 to 20 trace elements on all samples, field and laboratory measurements were made on water samples. Analytical data and field measurements are presented in tabular hardcopy and fiche format. Four full-size overlays for use with the Kingman NTMS 1:250,000 quadrangle are included. Water sample site locations, water sample uranium concentration, sediment sample site locations, and sediment sample total uranium concentration are shown on the separate overlays. A general description of the area and the rock type distribution is presented. Some of the data in this report have been issued previously in "Preliminary Report on the Roach Lake Pilot Study," GJBX-44(76), August 1976.

Supplementary data containing site location and uranium concentration data of water and sediment samples to accompany a report on hydrogeochemical and stream sediment reconnaissance in Nevada.
