Being only 6 feet above the ‘Dry Season’ water Level, it is impassable during the majority of the wet season (Dec- April) when the water level is 40 feet above it. As all the trees you can see in this photo go under water

This water having originated in Arnhem Land flows through the Nitmiluk Katherine Gorge, passes through the town of Katherine and on to the Daly River where its journey of over 400+ km takes it to Anson Bay in the Joseph Boneparte Gulf (only 100 km from Darwin).
 

Since the advent of the Katherine River Bridge in town the low level area has become a nature reserve and a local swimming hole. The water depth here is only around 3-5 feet max and ideal for families.

Under the Low level bridge is a weir which although made of concrete gives the River a bit of character as the water cascades several feet to the lower level.
 

The Western side of the Low Level Nature Reserve up top of the river bank has a large grassed shady picnic area, playground for the kids and several free (or cheap) gas bbq facilities to enjoy a relaxing Northern Territory day.

So go to the Butcher grab a few steaks and have a dip in the River & a BBQ.

Take the fishing rod if you are around in April-June before it gets too cold for the Barra.
