Note: The state revamped the way it notifies the public of the changing advisories by goi...ng to a color-coded system for signs. An orange sign means a “recreational public health advisory” is in effect. Those signs will warn individuals who are elderly, are very young or people with compromised immune systems that swimming and wading is not recommended.
A red sign means a “no contact advisory” is in place. These signs will warn people that unsafe toxins are present in the water and contact should be avoided.
