Benefits of WHS membership include:
  • Monthly meetings with distinguished speaker presentations on a wide spectrum of hydrologic topics.
  • Annual field trip to locations within greater Puget Sound to inspect and view on-the-ground projects.
  • Opportunities to post and receive announcements on hydrology issues and events in our monthly e-newsletter.
