A WATER quality study at Lake Albert and Narrung Narrows will look at ways of maintaining ecological health in the region.

The 12-month study was announced by federal environment minister Tony Burke and South Australian water minister Paul Caica this morning.

Lake Albert and the Narrung Narrows form a critical part of the Corrong, Lower Lakes and the Murray Mouth wetland of international significance.

Mr Burke said the study would evaluate the feasibility of long-term management solutions.

"This study will consider the impact of varying lake levels and complementary works required in the Narrung Narrows and elsewhere to improve water exchange between Lake Albert and Lake Alexandrina," Mr Burke said.

The study will receive 90 per cent of its funding from the Federal Government and the rest from the state.
