BAD news for recreational users of Lake Dyer and Atkinson Dam which will remain off limits to water use until the new year.

Activities such as swimming, water-skiing, boating, kayaking, canoeing and sailing are not permitted while the ban is in force but off-water recreational activities are not affected

Seqwater closed the lakes to recreational users last month for public health reasons due to blue-green algae and now have confirmed they won't open for Christmas.

Seqwater can't say for definite what is causing the blue-green algae, which releases toxins which can produce a potential health risk to humans and animals, but it could be insufficient nutrients in the water, hotter temperatures or increased cloudiness of the water.

Seqwater say blue-green algae are naturally occurring organisms and their presence in rivers, lakes and waterways are an important part of a healthy ecosystem and in normal conditions exist in low numbers.

"However, under certain conditions the algae can grow very rapidly. This is referred to as an 'algal bloom' and, at rapid growth rates, can become a dominating, and sometimes toxic, nuisance in our waterways," Seqwater say.

Seqwater said they would continue undertaking regular water quality monitoring.

"[We will] re-open the lake when it is safe to do so," they said in response to questions from the Gatton Star.

"The community will continue to be updated via our website and social media channels."
