For nearly nine months of the year the river proper is confined to a narrow channel two to three hundred feet wide. During the remainder of the year, however, the river is subject to periodical floodings resulting from heavy tropical rain on its water-shed and for periods of a week of more at a time the low level bridge is covered by flood water. The dislocation of rail traffic which results from these periodical floodings has been a matter of serious concern to the Queensland authorities for many years and a decision was made to construct a high level rail and road bridge to replace the existing structure. Construction was commenced, but before it proceeded far, it was considered desirable that the depth of the bedrock, previously examined, should be established without doubt. In view of the uncertainty of the depth to be drilled and the very considerable difficulty in drilling through alternating layers of drift sand and boulder wash, a request was made by the Co-ordinator General of Public works for Queensland for a geophysical investigation of the site. A survey was carried out by the geophysical section of the Commonwealth Bureau of Mineral Resources during August and September, 1947. The investigation of the results is far from complete but the seismic method gave such concise results that this preliminary statement is justified. Geology, geophysical methods, results, interpretation, and testing are discussed in this report.
