Washington Hydrologic Society



Welcome to the Washington Hydrologic Society (WHS)

We are a non-profit organization whose mission is to facilitate the dissemination of knowledge about the technical information and professional practice of the hydrological sciences. Our members come from throughout Washington State and the Pacific Northwest and include hydrogeologists, hydrologists, engineers, aquatic biologists, environmental scientists attorneys, and planners. Members work in government, private industry, tribes, and academia.


WHS organizes quarterly meetings with invited speakers. Topics cover a wide range including, but not limited to, ground- and surface-water quantity and quality, contaminant hydrology, sediment quality and transport, hydrological modeling, fisheries biology, aquatic ecology, river restoration, water policy, water management and allocation, tribal water issues, flood control, dams and hydropower, climate change, and new technologies.

Meetings are typically held on a Wednesday evening in Fall, Winter, and Spring. A yearly field trip occurs each Summer. Meetings are held at locations throughout the Puget Sound region, usually in Seattle, Tacoma, Olympia, or Everett.
