This study represents the findings of research done on the Jones and Johnson farms, "situated in Johnson Branch Park in the north-central portion of the Ray Roberts Lake area." The purpose of the study was to offset future disturbances and damages to these farmsteads, and it includes "archival investigations, architectural documentation, oral-history interviews of long-time area residents and family members, farm equipment and artifact analyses, archaeological excavations, stabilization measures, and the development of interpretative exhibits for area schools, museums, and the general public" (p. i).
"This study was implemented voluntarily by personnel at Dallas Water Utilities in response to concerns that the Dallas Central Wastewater Treatment Plant was adversely affecting downstream water quality." The treatment plant was studied to determine whether it was "discharging toxic materials in toxic amounts to the Trinity River" (p. 1).
