Management of water levels in Lake Jualbup

The Environmental Protection Authority (EPA) has received a referral on the proposal to maintain a permanent water body in Lake Jualbup. The proposal is to convert Lake Jualbup into a constructed lake by lining the lake bed with a polymer additive and constructing sloped banks and concrete walls to reduce water loss to the surrounding environment. The EPA considers that the potential environmental issues associated with the proposal are:
• Water quality impacts on aquatic fauna,
• Impacts on the Oblong Turtle through binding the sediment; and
• Potential for Acid Sulphate Soils (ASS) exposure down gradient of the
Lake.
