In the Murray River valley irrigation has caused salinity problems. Land surrounding the town of Werrimull in the northwest of Victoria have been affected by salinity due to land clearing.he Eastern Mallee and the Western Mallee of Western Australia are areas that are prone to salinity with little remedial action being undertaken to rectify the problem. Lands surrounding Lake Bryde-East Lake Bryde and Dumbleyung Lake have also been affected.
Historically the areas around Waikerie and Woolpunda in South Australia contribute close to 350 tonnes of salt a day between them. In South Australia the development of salt interception schemes has reduced this figure by more than 85%. Thatâs over 300 tonnes of salt that is no longer going into the Murray every day.The inception schemes have lowered the average salinity at Morgan by 22 EC units.t that time the whole land mass started to rise out of the sea (about 100 million years ago). Salt water flowed away from the emerging land back into the ocean, and a river was born which would eventually become the present-day Murray (see the beginnings).
