CyanoAlert

20 January 2011

A blue-green algal health advisory that has been in effect at Fairview Lake,  Portland (Oregon, USA), since July 2010 has just been lifted!  More phosphorus bans are being initiated, with Ramsey Lake (Sudbury) being the latest on the list.  Information webinars are becoming more popular in the US, with one on reducing agricultural pollution scheduled for January 29th. Iowa has reported that the number of polluted waterways in the state has reached 570, the highest in 14 years.

In New Zealand, warnings have been issued for the Ashley River (Canterbury), while cyanobacteria are causing problems in the Tararua District – where water restrictions now affect much of the lower North Island.
