[en] This report presents the results of the Winnemucca Dry Lake Basin, Nevada, orientation study in the Lovelock and Reno 1⁰ x 2⁰ quadrangles of the National Topographic Map Series (NTMS). Wet, dry, and playa sediment samples were collected throughout the 597 km² semi-arid, closed basin. Water samples were collected at the few available streams 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. Eight full-size overlays for use with the Lovelock and Reno NTMS 1:250,000 quadrangles 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 Winnemucca Dry Lake Basin Pilot Study,'' GJBX-41(76), August 1976
