Why are swimming beaches sometimes closed?
Several factors can cause bacterial levels to increase, which can result in a beach
closing. Some of the reasons for increased bacterial levels may be swimmer load
and swimmer practices; high water temperature, waterfowl droppings, animal wastes, rainfall and low water levels. When lab results indicate increased levels of bacteria, such as E. coli, city staff has to determine what measures need to be taken to protect the public health. These measures may include more frequent testing,
removing waterfowl, and educating users on personal hygienic practices at the beach.
