2019 Southern Spring Flow – Productivity Monitoring

During the 2019 Southern Spring Flow event , water for the environment was added to flows in the River Murray to help provide food and habitat for fish and other aquatic animals. The Southern Spring flow delivered water to six major wetland sites through thousands of kilometres of rivers. Scientists at CSIRO monitored how carbon and nutrients changed along the length of the river to understand whether the spring flow boosted the aquatic food web. A companion study monitored how plankton, fish food, responded (funded by the Commonwealth Environmental Water Office). The measured increases in carbon, nutrients and plankton are important food for small yabbies, crays and small fish and means the River Murray food chain got a productivity boost from the delivery of water for the environment.
