During August and September, 1948, the writer made an archaeological survey of the Lavon Reservoir area in Collin County, Texas. This was a project of the River Basin Surveys program of archaeological salvage, undertaken by the Smithsonian Institution, with the cooperation of the Corps of Engineers and the National Park Service. This reservoir is being built on the East Fork of the Trinity River near Wylie, Texas and approximately 25 miles northeast of Dallas.

Twenty-five sites were located in or near the proposed reservoir area during the course of this survey. Nineteen of these appear to be small, temporary campsites, some producing a few potsherds; others are apparently non-pottery sites. However, six of the sites appear to be permanent village locations occupied by relatively large groups of pottery-using people over a long period of time. The material from these sites is in the process of laboratory analysis at the present time and a statement of the cultural affiliations involved cannot yet be made.
