The greatest flood in the upper Murrumbidgee occurred on this day (May 27) in 1925.

The area around Canberra, north from Cooma, received record rains in early May that year but on the night of May 26 and morning of May 27, the falls were unprecedented before or since.

Belconnen (in the Canberra area) had 161mm to 9am on May 27.  Bungendore had 152mm (after a record 121mm just two weeks earlier) and Queanbeyan 189mm, almost double any other daily fall in the past 100 years.

Falls of over 100mm fell as war west as Burrinjuck Dam.

In the space of three weeks the upper Murrumbidgee received more rain than it has had in whole years in recent times.
