Puget Sound mosquito fleet
The Puget Sound mosquito fleet was a multitude of private transportation companies running smaller passenger and freight boats on Puget Sound and nearby waterways and rivers. This large group of steamers and sternwheelers plied the waters of Puget Sound, stopping at every waterfront dock. The historical period defining the beginning and end of the mosquito fleet is ambiguous, but the peak of activity occurred between the First and Second World Wars.
