The U.S. Army Corps of Engineers (USACE), Fort Worth District, is investigating the water resource problems, needs, and opportunities within the Big Fossil Creek drainage in Tarrant County, Texas. The effort focuses on describing existing conditions and identifying measures to minimize and control flood loss within a 48,396.8-acre area of the drainage north of the city of Fort Worth. Geo-Marine, Inc., of Plano, Texas, was contracted by the USACE to assess the potential for historic properties within the drainage area. Background research and a pedestrian reconnaissance survey of the project area were carried out and a geographical information systems (GIS) model was designed to evaluate the probability for both surface and subsurface cultural resources deposits within the project area and to make recommendations for further treatment of any properties.
