What’s a Spillway…and Why Should You Care?

They may just look like big pipes, but they have a very important job – to help protect you from flooding. What you see in the time-lapse video is the installation of the principal spillway pipe, a major structural part of the Papio NRD’s new flood mitigation reservoir in Gretna, NE, slated to be completed in May of 2025.

So, what’s a spillway? In simple terms, a spillway serves as an outlet to ensure the safe passage of excess water if the water level of the reservoir goes above its regular permanent elevation.

Why should you care about this? While a flood mitigation reservoir’s primary job is to help protect you and your property from flooding events, it also creates recreational opportunities for the community. Once the project (located southwest of 168th Street and Giles Road) is completed, citizens can enjoy recreation amenities, such as fisheries, trails, kayak launches, and a picnic area – while at the same time, knowing their families are being safeguarded. A double win!

We will continue to keep you updated on the project’s progress and want to thank crews from Houston Engineering and Valley Corporation for all their hard work!
