The research was conducted under contract with the Rock Island District, United States Army Corps of Engineers, to assist in management problems related to maintenance of the nine-foot channel. Initially the survey was designed to sample 20 percent of the Federal Land, but the final sample comprised 25 percent. Map evaluation and gemorphological fieldwork revealed that almost the entire land surfae of the pool had been inundated repeatedly, leaving a mantle of silt that conceals virtually the entire survey area. Eleven previously unrecorded prehistoric sites were found, including one Archaic shell miden with a C-14 date of 5680 + minus 75BP (ISGS-829); two sites also had historic 19th-century components. 收起
