When is a beach closed?
A beach will be closed at the discretion of the County Health Officer if there is an imminent public health threat such as a known discharge of pollutants. Closed signs stating "KEEP OUT. Sewage Contaminated Water. Contact with Water May Cause Illness" will be posted at the beach.

When a beach is listed under closed status, stay at least 1/4 mile (440 yards) away from both sides of the creek mouth.
