The Katherine River tipped 15 metres at the Katherine Bridge at around 3.50pm on Saturday.

Following two dismal wet seasons - which saw the river height dwindle to as low as 1.41 metres deep at around the same time of year in 2019, and peak to barely above six metres during the 2018 to 2019 wet season - the river has been a spectacle, attracting a number of curious onlookers.

The height of the river and the lack of drenching rain had been a major concern since 2018, as pastoralists were forced to destock their cattle, and homeowners had to dig deeper bores in search of water.

The Bureau of Meteorology issued a minor flood warning for the region on Friday, however the river is not expected to flow above the minor flood level of 16 metres.

"Widespread rainfall totals of 100 - 130 mm have fallen over parts of the Katherine River during the past two days and 50 - 100 mm in the lower catchment overnight on wet catchments with river levels rising in response," a statement from the Bureau reads.

"The Katherine River at Nitmiluk Centre peaked at 5.30 metres around 4:40 am Saturday 20 February and is currently at 4.37 metres and steady. The Katherine River at Nitmiluk Centre is expected to remain above the minor flood level (three metres) during Saturday and into Sunday. Further rainfall over the next few days may contribute to renewed rises in river levels.

"The Katherine River at Katherine Bridge is currently at 15.05 metres and steady. The Katherine River at Katherine Bridge is expected to remain below the minor flood level (16 m) during Saturday and into Sunday. The river level is likely to remain around 15 metres early Saturday evening before falling overnight. Further rainfall is possible over the next few days and may contribute to renewed river rises."

Northern Territory Police Commander Janelle Tonkin said that with river levels expected to hover at the 15 metre mark, there is no cause for alarm.

"We say it often, however the message remains the same - please don't drive through flooded causeways, don't go into flooded waterways and don't launch water crafts into swollen rivers," Commander Tonkin said.

"The unseen hazards under flood waters could result in serious consequences.

"No flooding is expected in the town of Katherine today, however we will continue to monitor the situation and advise the community if further action is required.

"We are aware of an image currently circulating local social media pages of a person on a jetski on the Katherine River earlier today.

"While this is not a criminal offence, it is just plain dangerous and in the instance someone becomes trapped or stuck in the river - they don't just put themselves at risk but our local emergency services members at risk also."
