Lunch & Learn: Getting It Right at the Water’s Edge — Practical Insights into OHWM and SDAM

December 10, 2025
11:00am to 11:45am

[Participation Link will be sent out before the event, please RSVP]

Join us for a practical, field-based session with Sheryl Creer of Stantec, who has completed dozens of Ordinary High Water Mark and SDAM assessments across diverse landscapes. Sheryl will share lessons learned, data collection tips, and real-world case studies showing how these tools can improve consistency, defensibility, and collaboration with regulators.
Whether you’re new to these methods or refining your field approach, you’ll come away with insights to make your next delineation more efficient and confident.

Guest: Sheryl Creer Bio
Sheryl Creer is a Senior Botanist and Wetland Specialist at Stantec, based in California, with more than a decade of hands-on experience in environmental consulting across California, Nevada, Oregon, and Arizona. She holds both a B.Sc. in Botany and an M.Sc. in Biology from San Francisco State University.

At Stantec, Sheryl supports large-scale infrastructure and utilities projects—solar, long-haul fiber, transportation, electric transmission corridors—leading floristic surveys and aquatic resource delineations and writing technical reports as well as leading agency coordination in aquatic resource permitting. Her work bridges field biology, regulatory frameworks, and practical constraints in dynamic project settings.

In our upcoming Lunch & Learn, Sheryl will draw on this rich background to share real-world insights on applying OHWM and the Streamflow Duration Assessment Method (SDAM) in the field: how to better structure data collection, avoid common pitfalls, and optimize workflow for both accuracy and efficiency.
