The Department of Environment and Water (DEW) is reminding water users along the River Murray in South Australia to make sure they do not exceed their water allocations and submit their meter readings quarterly.
The long-standing requirements to make sure they have not used more than their available allocation are in place so all of the state's River Murray water users can access the water they need.
They are also aimed at helping water flow through the river system.
The changes, made in 2019, require meter readings to be submitted to DEW at the end of each quarter. Anyone who goes over their account limit will face penalties.
DEW water licencing general manager Mike Fuller said year-long monitoring would help water users stay within their limit.
"The majority of South Australia's River Murray users do the right thing and remain within their available allocation," he said.
"This change does not affect those water users who operate within the terms of their water account and ensure a credit balance at the end of each quarter."
Mr Fuller said meter readings could be submitted online at any time, and water users had the opportunity to have a water usage advice statement - similar to a bank statement, but for water - sent through via email or SMS.
"This helps ensure they are monitoring water use and remaining within their available water allocation," he said.
Quarter three of the 2019-20 water use year ends on March 31, 2020.
Any instance where the available allocation on a water account after 5pm on March 31 has been exceeded will result in a penalty.
Any water trades for quarter three to be considered by DEW must be applied for before 5pm on March 31, 2020.
