DERWENT BASIN MONTHLY RAINFALL
Monthly average rainfall for Lake St. Clair National Park is shown below. This location is ideal for monitoring inflow into the large storage lakes of the Derwent basin, in particular Lake St. Clair, but note that rainfall is generally lower in the Lower Derwent region.
GORDON BASIN MONTHLY RAINFALL
Monthly average rainfall for Strathgordon Village, near Lake Gordon, is shown below.
ESK BASIN MONTHLY RAINFALL
Monthly average rainfall for Liawenee, near Great Lake, is shown below.
PIEMAN/KING MONTHLY RAINFALL
Median (note not mean, not available from BoM) monthly rainfall at Mt. Read is shown below:
