The Lavon Dam and Reservoir, under construction by the Corps of Engineers, Department of the Army, is one of the many projects throughout the country which will soon obliterate information relating to the prehistory of North America. This particular project is located on the East Fork of the Trinity River in Collin County, Texas, 21 miles northeast of Dallas. It was scheduled for completion in January, 1952.
The Trinity River is one of several major rivers flowing in a southeasterly direction across the state of Texas. It heads in four branches north and northwest of the city of Dallas and flows into Galveston Bay and thence into the Gulf of Mexico, approximately 40 miles due east of the city of Houston. The East Fork (and its principal tributary, Pilot Grove Creek) is the easternmost of the headwater branches. It rises in Grayson County and enters the main stream in southwestern Kaufman County.
