A medium risk warning is in place for the Hutt River at Silverstream.
Moderate growth of toxic algal mats has been recorded at this site. River users, particularly those with dogs, should avoid contact with algal mats in this stretch of river. The risk from toxic algae at other sites monitored in the Hutt River is currently low but warning signs are in place as algal growth is likely to increase rapidly as the warm, dry weather continues.
