Development in League City threatens wetlands

Hurricane Harvey was tough on wetlands, and even tougher on wetland scientists like me. I have spent a career focusing on wetlands along the Upper Texas Gulf Coast. Like the Lorax, I speak for the wetlands (and the prairies and forests and all the rest of it!). I have devoted considerable energy to expounding all of the virtues of wetlands, including their ability to decrease downstream flooding. So much so that at least one top flood official accused me believing in “magic wetlands”. He didn’t think wetlands did all that much in terms of stormwater detention (or anything else apparently).

As with many other aspects of our lives, Harvey changed everything. It modified my views on upstream wetlands and flood control. Harvey totally overwhelmed every single prairie-pothole wetland on the Katy Prairie, and on every other prairie in our area for that matter. All of these wetlands filled with water very quickly very early in the storm and all of the soils in or out of the wetlands became saturated very early as well, such that virtually all the rain falling anywhere, even on the sandiest of soils, ran off the landscape and into our creeks and bayous. And then the water in the bayous rose and the rest is burned into our memories. (more…)
