This report lists the depths of water and the consistency of the seabed surrounding the Warrnambool Harbour in October 1929, The information, often referred to as 'soundings', was obtained by Jet Probing,. In earlier days a lead line was used to perform a similar task. The author of the document is unknown. Jet Probing is a method used for underwater archaeology, cable installation and coastal engineering. A jet probe is a machine that produces a strong jet of water that penetrates the layers of sediment on the seabed, determining their depth, thickness and consistency. It provides a survey of the seabed and can be used as an aid to engineering design and construction. The report mentions lining up with the wooden jetty, the end of the breakwater and the leading lights. It mentions sand, loose rock and rock. It tells of stopping work due to the water being too rough, the pipe choking, difficulty in connecting pipes, and pipe joint breaking as it tried to get through the sand, The report in the document is significant for its connection with the Warrnambool Harbour, Warrnambool Breakwater, Warrnambool Jetty and Lady Bay. The report gives figures for the depth and consistency of the water and seabed at a particular point in time and can be used to compart with similar figures taken at different times. The results could determine plans for future engineering works.Report, titled 'Jet Probings, Warrnambool Harbour'. Two pages of cream coloured paper with hand written notes in pen and ink. Report covers three days of Jet Probings, with resulting figures and comments, for the depths of the surroundings of the Warrnambool Harbour. The report is in point form, with some underlining. Dates of recordings are 14-10-29, 15-10-29 and 16-10-29. (1929) The situation of the harbour had become a real problem by 1910 and required continuous dredging. In 1914 the Breakwater was extended but proved to be a failure because the work began to subside and by 1920 about two thirds of the harbour was silted up. Alterations made in the 1920's increased the silting problem. The soundings and Jet Probings were done after the Royal Commission of 1923, when the damaged stonework on the seaward side of the Warrnambool Breakwater, caused by the action of the sea, was the subject of enquiry. A conference between the Public Works, Water Commission and the Harbour Trust concluded that it would less costly to make repairs to prevent further damage rather than replaced the damage portion of the wall. A contract was raised in late 1924 to deposit rubble on the damaged side of the breakwater to minimise the Southern Ocean’s destructive action and work had started by August 1925. By the 1940's the harbour was no longer used. More alterations were made in the 1950's and 1960's. document, depth, warrnambool harbour, 1929, soundings, jet probe, jet probing, seabed, map of seabed, underwater engineering, warrnambool jetty, warrnambool breakwater, breakwater upgrade, leading lights, chart the harbour, flagstaff hill, warrnambool, flagstaff hill maritime museum & village, maritime museum, maritime village, shipwreck coast, lady bay, port of warrnambool, breakwater, jetty, pier, vhr h2024, royal commission, 1923, public works, water commission, harbour trust, victorian harbours

Breakwater navigation lights are placed at the end of the breakwaters to warn incoming vessels of the end of the structure, as a marine safety measure. The subject item was such a light believed to have been placed at the end of Warrnambool's breakwater around 1915 when it was extended. The light had remained in place for many years until it was probably removed when the structure was undergoing rock armouring repairs to the end of the breakwater in 1975. The light had been placed in a council storage shed probably from the time when the structure was undergoing these repairs in 1975. In 2014 the light was removed from the storage shed and donated to Flagstaff Hill museum. History: Warrnambool breakwater plans were drawn up by 1874 and approval was given for preliminary construction work to start but when the money ran out, the works stopped. With a number of quick changes of government the “Warrnambool” breakwater project was kicked from one Victorian state government to another. Then finally in 1879, the eminent British harbour engineer Sir John Coode was asked to design a breakwater. His first design was for a 1800 feet long structure but that was scaled back to 900 feet and construction finally began in 1884. This structure was attributed in causing major siltation of Lady bay, as a consequence the breakwater was again extended in 1915. In 1975, the rock armouring at the end of the breakwater was added but by 1979 another impact study was calling for the breakwater to be removed altogether. The Heritage Council Victoria, regard the Warrnambool breakwater is of historical significance to the state as one of the most important maritime engineering projects that was undertaken in Victoria during the late nineteenth century. The light is also as part of this structure regarded as a significant item of historical interest.Marker light or navigation light.
