High levels of toxic algae in Poorman Valley Stream

Potentially toxic algae, also known as cyanobacteria, has been found at high levels in Poorman Valley Stream.

The two sites affected are by Seaview Road, downstream of Nayland College and in Isel Park by Main Road Stoke, between the footbridge and Main Road.

The Nelson Marlborough District Health Board, Public Health Service and Nelson City Council advise the public to avoid entering the stream themselves or allowing their dogs to go in the water until we issue a notice that the algae is no longer a problem.

Warning signs have been erected at both sites and will be removed when the cyanobacteria is no longer present.

Toxic algae is currently not at high levels in other Nelson streams and rivers.
