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).
