around Miami, but some of the problems led to remote parts of the Everglades and Big Cypress Swamp. For example, geologic reconnaissance studies were made over most of southern Florida so that the areas of outcrop of the different formations could be determined and the geologic structure of southeastern Florida understood; the flow of arterial canals was measured in the Everglades, and analyses were made of records of stage and flow for Lake Okeechobee and its connecting channels and basins for the purpose of evaluating the more distant possible sources of surface water supplies and for defining the hydrology of the whole drainage area.
The writers wish to acknowledge gratefully the assistance given the
U. S. Geological Survey by Dade County and the Cities of Miami, Miami Beach, and Coral Gables, and by the many persons, agencies, organizations, and firms who have provided information and records, and who have in any way helped make available the facilities to carry on the investigation of which this interim report is a product. So many have aided that it is impossible to list them in a brief paper of this kind, but a full statement of acknowledgments will appear in the comprehensive report to follow.
As the investigation has proceeded reports have been prepared from time to time by members of the staff. Several reports have been written that are restricted because of their military nature. The unrestricted reports are as follows:
