While the high levels of one species of cyanobacteria spp., are no longer present in Castle Semple loch there is an increasing amount of another potentially toxic blue-green algae (Anabaena spiroides).  Visitors should still avoid activities that involve prolonged contact with the loch water such as swimming.
