Overview

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.  Field visits to each of the SMA water types will give you the opportunity to apply the methods discussed in the classroom.        

                       

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?
