In 1929, during a period of rapid developments at the lab, Charles M. Allen wrote that Alden's motto was chosen as "When you are through changing, you are through." 

Fast-forward to 2020. As we enter our 126th year, change surrounds us at the lab—in the form of innovation. We continue to develop innovative and creative solutions to our clients’ most challenging problems, and it acts as a major motivation for our employees.

This edition of our newsletter gives you a quick glimpse into the kind of work that drives our Fisheries Engineering folks, including a two-part study for eel passage at hydropower projects.

Check it out. And let us know—what motivates you?
