The Big and Little Darby Creeks are some of the most important streams in not just Ohio, but in the entire Midwest and the nation. The Darby Watershed is an outstanding natural resource home to a nationally significant assemblage of rare and imperiled aquatic biodiversity. Both the Big and Little Darby Creeks are federally listed as National Scenic Rivers. But their health is declining. And anticipated urban development threatens their futures.

Sign-up to protect the Darby Creek!


August 2023:

Following the Ohio EPA’s announcement on June 13, 2023 to extend the existing Big Darby Creek protections that exist in Franklin County to Madison County and Plain City, the Ohio Environmental Council and partners filed a comment calling for additional protections for those sections of the Big Darby Creek. The additional necessary protections focus on the potential impacts, especially stormwater, of the new development in these areas without proper planning.

January 2023:

On January 31, the Ohio Environmental Council, Center for Biological Diversity, Darby Creek Association, American Rivers, Forest Keeper, Ohio Scenic Rivers Association, Sierra Club Ohio, and the Nature Conservancy, who collectively submitted a technical comment to the Ohio EPA to designate the Big and Little Darby Creeks as Outstanding National Resource Waters (ONRW)—the strongest protection under the Clean Water Act. In total, over three thousand people submitted public comments in support of the ONRW designation for the Creeks.

To kick off the new year OEC and partners believed it was essential to get the Big and Little Darby Creeks designated as Outstanding National Resource Waters. This designation would prohibit any sources of discharge that may harm the “chemical and biological quality” of the water. In order to be classified as such a water body must have national ecological significance, national recreational significance, or a unique combination of biological characteristics of which the Big and Little Darby satisfy all three. OEC Members submitted hundreds of comments to tell Ohio EPA to formally categorize Big and Little Darby Creeks as Outstanding National Resource Waters.

November 2022:

The OEC, Center for Biological Diversity, and Darby Creek Association filed an appeal of a Wastewater expansion permit. To learn more about this permit click here.
