Improvement In Algal Bloom At Burrinjuck Dam

February 1, 2000 Tumut & Adelong Times

There are signs the recent algal bloom at Burrinjuck Dam has improved, but recreational users have been asked to maintain a close lookout and thoroughly clean any fish they catch.

Last week a high alert for the potentially toxic blue green algae species "Mierocystis" was been issued for the Main Basin of the dam, the junction of the Main Basin with the Murrumbidgee Arm upstream to Skillens Flat and the lower reaches of the Goodradigbee Arm.

Whilst the algal bloom particularly within the Main Basin and the Goodradigbee Arm has improved dramatically the Department of Land and Water Conservation says users should keep a lookout for algal specking and to avoid any obvious scums on the water. The algae will also be concentrated in the wind swept inlets and these areas are to avoided where possible.

Mr Justin Nancarrow, Water Quality Officer, said that "If the windy and mild conditions that we have experienced recently continue, the algal problems should improve.

Those planning to visit Burrinjuck Dam need not cancel plans, but should contact local park managers or government authorities for advice on water supply and local conditions. They should also be aware of algal warning signs and information at the resorts and storages.

Anglers should ensure any fish caught are well cleaned, and that only the muscle flesh is eaten, as livers and stomachs may contain algal toxins. Yabbies should not be eaten due to the possibility of toxin contamination. Dogs should he kept from algal blooms, as they are especially susceptible to toxins.

The Department of Land and Water Conservation says it will continue frequent monitoring until conditions improve.
