Nebraska has issued  health alerts for three lakes. Officials said Friday that water samples taken from the Lone State Lake in Fillmore County, Rockford Lake in Gage County and Maskenthine Lake in Stanton County showed high levels of a toxin released by blue-green algae.  Oregon public health officials have issued a warning about high algae levels in Diamond Lake just north of Crater Lake National Park.

In the UK the algal bloom in Pembrokeshire continues.
