This training provides information and methods for determining the ordinary high water mark (OHWM) as defined in the state Shoreline Management Act (SMA). Waters regulated under the SMA include all tidal waters, streams greater than 20 cubic feet per second mean annual flow, water bodies greater than 20 acres in size, and any associated wetlands and deltas.       

In this training, you will learn answers to these questions:      


  • How is the OHWM defined and where does it apply?
  • What is the regulatory context and history of the OHWM?
  • Why it is important to use field indicators to determine the OHWM?
  • What are the most reliable field indicators on tidal waters, streams, lakes, and associated wetlands?
  • What are some common misconceptions about OHWM determinations?

The three-day training includes two virtual sessions that will take place on Zoom on October 5 and October 6 (9:00 AM - 12:30 PM). Participants will have the option to log on 15 minutes early on day 1 for a brief Zoom introduction. 


On October 8, the participants will complete the field component of the training. Participants will practice how to determine the OHWM at four field sites in Thurston County with an instructor and 5-7 participants. The sites include a high-energy marine site (Burfoot Park), low-energy marine site (Woodland Creek), lake site (Longs Pond), and stream site (Pioneer Park). Please block your calendar from 8:30 AM - 3:30 PM for the field component. 


During the field component, all participants will be expected to follow Washington Department of Ecology’s COVID-19 guidelines at the time of the training. You will likely be asked to complete a health survey 12 hours before the field component and wear a mask. After registering for the course, please email Sara Brostrom (bros461@ecy.wa.gov) if joining the in-person field session in Thurston County is a barrier to participating in the training. We will work with you to find another option (11 AICP CM Credits/CEP Points).
