Carlo and Ettore's evidence was reported in The Argus of October 21 (see here) Ettore's evidence is interesting as it shows the huge volume of water that swept down the Yarra during this flood.
Mr Ettore Checchi of the Victorian Water Supply department, the first witness examined submitted a number of plans showing the levels of the floods at different points of the river. At Warrandyte the volume of flood water was 1,650, 000 cubic feet per minute ; and at Dights Falls he estimated the volume to be 2,290,300 cubic feet per minute. Other authorities had formed different estimates as to the volume at the last-named and a mean average of 2,167,600 cubic feet per minute was given. At Gardiners Creek the mean average as to the volume of the flood water was 2,206,200. At Prince's-bridge the discharge would be practically the same at at Gardiner's Creek. The discharge of water at the St Kilda road was 495,800 cubic feet per minute, with a volume of 147ft per minute. The mean volume of water at the Saltwater River was 1,188,600 cubic feet per minute. The total discharge of water at the junction of the Saltwater River was 2,899,000 cubic feet per minute, with allowance for diversion at Prince's-bridge only. The total discharge of water into the bay was 3,395,000 cubic feet per minute. (The Argus of October 21, see here)
Mr. Catani of the Public Works department, said there was a discrepancy between the levels supplied by him and those furnished by the officers of the Harbour Trust as to the flood waters at the Queen's-bridge. Above and below the bridge the same level of water he found obtained, the abutments of the bridge offering no obstruction to the continuous flow of the water. The levels he had marked on his plans were in agreement with those obtained by the Railway department. From his own observation he had fixed the levels of the flood of 1891. (The Argus of October 21, see here)
One of the solutions to stop the Yarra River flooding was to widen the river and straighten it's course and this work, between the Princes Bridge and the Cremorne Railway Bridge, was undertaken by Carlo Catani and the Public Works Department in 1896 and 1897, you can read more about it here. This work also led to the creation of Alexandra Avenue and the Alexandra Gardens, two other projects of Carlo's.
Twenty nine houses were 'rendered uninhabitable' by the flood, and you can see why by this photo.
