Logan River 23 M and 135 M tidal barrage sites seismic refraction survey, Queensland 1959

Updated: 2026-05-04

The report describes the results of seismic; refraction surveys at the 2.3M and 13.5M, Logan River tidal barrage site near Beenleigh, Queensland. The maximum depth to bedrock at the 2.3M site is probably 130 ft at a point, about 350 ft from the southern bank. The maximum depth to bedrock at the 13.5M site is about 80ft, near the centre of the stream. At each site test drilling to check the seismic results is recommended, before further development is planned.
