The Iowa Environmental Council on Wednesday announced a successful legal action to protect the water quality of Yeader Creek, which flows into Easter Lake in Des Moines. The environmental coalition filed a petition for judicial review on April 30 in state district court against the Iowa Department of Natural Resources, arguing that DNR had issued a stormwater discharge permit that did not protect water quality in the creek as required by state and federal law. Yeader Creek is located in southeast Des Moines and feeds into Easter Lake, a popular recreation area currently undergoing a multimillion-dollar watershed restoration project to improve water quality, protect wildlife and enhance recreation opportunities in the area. The DNR revised the permit to address the environmental council’s concerns, and the council subsequently filed to dismiss its petition on Aug. 1, the IEC said in a release. The creek has been listed as one of the state’s “impaired waters” since 1998, and while improved, it still has low oxygen levels. “Our suit forced revision of the permit to enforce protections as required by law that will ultimately help to further improve Yeader Creek,” Jennifer Terry, the IEC’s executive director, said in a statement.
