A lake that learns can change a region. Sam Martin, Director of Communications and Engagement at Cleveland Water Alliance (CWA), shares how Lake Erie has become the world’s largest digitally-connected freshwater test bed—and why that matters for public health, utility costs, and the next wave of water-tech jobs. 

Sam walks us through the water economy—everything from maritime logistics and treatment plants to sensing, analytics, and policy—and explains why real-world testing beats lab demos every time. The CWA acts as matchmaker between innovators and end users, backing pilot projects with insurance and support. It makes a compelling case for Cleveland as a freshwater innovation capital.

A new crew of superheroes, the Lake Erie League, is turning everyday systems into comic-book stories for kids and teachers to use in the classroom. Across eight origin tales, these northeast Ohio-inspired characters mirror very real aspects of the Sewer District's work, from massive tunneling machines whose creations tame storm overflows, to a miniaturized lab technician who can detect toxins no human eye could witness.

We start with Mackenzie, inspired by the tunnel boring machine behind Project Clean Lake, who illustrates how infrastructure projects matter underground and on the surface. Spectra brings lab science to life with tests that our students can replicate in class, while Rover and Dr. Tao tackle sewer and stream inspections and the microscopic world of water quality. Botanica's story is rooted stream protection, restoration, and sustainability, and Vis and Overwatch round out the Lake Erie League with CSI-style adventures as seen from the field -- and above it.

Teachers can request print copies of the new comic book for their classrooms and access the stories and activity sheets at neorsd.org/league.

Clevelanders might not know about a massive concrete structure hidden within Lakeview Cemetery. Standing 89 feet tall, Lakeview Dam represents both a marvel of 1970s engineering and a relic of outdated water-management approaches. Stormwater Program Manager Kim Colich gives some background on this imposing structure and explains how modern modeling and technology allow for different flood-control solutions today.

Beyond its engineering significance, the dam has gained fame as a filming location for Captain America: Winter Soldier and attracts curious tour groups. But its future remains an open question as water-management professionals balance flood-control needs with ecological goals and financial sustainability.

Whether you're fascinated by Cleveland history, engineering challenges, or environmental restoration, this look at one of our city's most impressive yet least-known structures reveals how our relationship with water continues to evolve.

Horticulturalist Joe Dwyer is part of the Sewer District's Stormwater Inspection & Maintenance (SWIM) team. 

"A large shade tree can take up to 4,000 gallons of stormwater throughout a year," Dwyer says, but problems with improper tree planting can reveal themselves often just as trees are reaching their prime environmental benefits. Joe highlights the importance of proper tree maintenance to support the District's stormwater-management work. 

We also discuss how trees communicate through underground fungal networks, bringing "winter interest" to our project sites, and the potential for beautifying roadsides with wildflowers.

Whether you're a casual observer of neighborhood greenery or an aspiring horticulturalist, you'll gain a deeper appreciation for the trees working silently around us.

We also want to share a handy resource from Cleveland Metroparks: a Tree Selector Tool that helps you select the best native species for your home or project, depending on your location, landscaping goals, amount of sun and shade, and other factors. The website also features a directory of local nurseries that carry native plants.  

Whether you’re a homeowner, landscape architect, land steward, or arborist, these Cleveland Metroparks resources can help you plan and obtain the right trees for your planting project.

Art meets infrastructure! The Northeast Ohio Regional Sewer District partnered with the nonprofit creative-writing center Literary Cleveland to host a reading of "Odes to Infrastructure," a newly-published zine, right in the heart of our Southerly Wastewater Treatment Plant. It was a celebration of our essential-yet-often-unseen water systems and, of course, Lake Erie.

Standing in the concrete tunnels where our treatment-plant workers normally move about, the Literary Cleveland writers delivered readings of poetry and short stories inspired by our infrastructure and its relationship to a cleaner Lake Erie. The echoing chamber amplified both their voices and the central message: connection. As one writer eloquently put it, "Stories and sewers bind us. They reveal our interconnectedness, our mutual dependence."

By bringing writers into treatment plants for tours and workshops Literary Cleveland created a new forum for highlighting our critical work.

The newly released 2025 Ohio Infrastructure Report Card delivers a sobering assessment of the systems we rely on daily but rarely think about. Ohio has made modest improvements since the last American Society of Civil Engineers' report in 2021, yet vulnerabilities persist.

Sewer District employees (and ASCE members) Derek Vogel and Lita Laven walk us through the grades and explain how federal infrastructure funding has breathed new life into long-neglected systems, particularly benefiting water, transit, and bridge projects across the state. However, the looming expiration of this funding in 2027 threatens to erase these hard-won gains. And with Ohio's stormwater infrastructure approaching the end of its designed lifespan, we're facing a perfect storm of aging systems and increasingly intense rainfall events.
