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 September 30th and October 1st (9:00 AM - 12:30 PM). On October 2nd, 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. Please block your calendar from 9:00 AM - 4:30 PM for the field component. Lunch will be provided on the field day.

Please email the Coastal Training Program (ecyrectpadmin@ecy.wa.gov) if you require an accommodation for this training (audio, visual, mobility, or other). Additionally, the program can offer a couple of scholarships to cover the registration fees with each training. Please reach out if you need a scholarship in order to participate in the training.
