Recent deaths and sickness in a number of ducks and geese on the lake leads us to believe that the there may be an outbreak of Avian Botulism in this lake.
Avian botulism outbreaks in wild water birds occur relatively frequently in ponds and lakes in England and Wales in periods when there is less oxygen in the water, such as during heat waves, because the bacteria which release the botulin toxin can occur in these conditions.
The type of botulin toxin most commonly associated with avian botulism has not been reported to be associated with human disease and therefore the risk to human health is considered to be very low.
However, as a precautionary measure for any lake or pond where dead birds have been found, the official advice is to not drink from the lake, avoiding swimming or paddling in the lake and prevent pets from entering the water.
If you notice any sick birds in the lake please phone the warden as soon as possible.
