The Victorian government has set up an open data directory that has some great information for hydrologists.
A few of the data sets:
- Index of Stream Condition
- Modified Rivers
- Groundwater-surface water interaction
- Baseflow separation analysis for unregulated rivers (1889 to 2012)
- Snow depth records for Falls Creek, Lake Mountain, Mount Baw Baw, Mount Buller, Mount Hotham and Mount Stirling.
