The 1886 Irrigation Act in Victoria introduced the first legislation in Australia designed to enable the creation of a detailed scheme for agricultural irrigation. Part of the legislation saw the use of government funds for local irrigation projects. These local projects were managed by local irrigation trusts. The Bacchus Marsh Irrigation and Water Supply Trust was formed in 1889.

The purpose for this map being created or the date when it was made has not been established. It appears to be documentation relating to a legal dispute by a landowner named O'Hagan and the Shire of Bacchus Marsh. Features identified on the map are allotment 5, section 16, Parish of Korkuperrimul, a 'cultivation paddock', a section of the Werribee River, the path of a section of a 'Main Channel', and a barrier or filled in section across the Werribee River called 'Lee's Filling'. The O'Hagan is likely to be Patrick O'Hagan, 1829-1914 who arrived in Bacchus Marsh in 1864 and was a prominent citizen and landowner in the area for many years until his death in 1914.Single page map showing allotment 5, section 16 in the Parish of Korkuperrimul, Scale 4 chains to inch.
