Clark County Department of Public Works (Clark County) has agreed to enter into an Administrative Order on Consent (AOC) for violation of Sections 301(a) and 404 of the Clean Water Act (CWA). From September 2018 through January 2019, Clark County used mechanized equipment to dredge sediments from channels and discharge dredged material for temporary haul roads into Laughlin Lagoon, an artificial inlet of the Colorado River in Laughlin, Nevada. The AOC requires Clark County to install informational/interpretive signs and no-wake buoys and to expand wetland areas by seeding southern cattail, in an effort to protect and provide critical habitat for three listed endangered species -- razorback sucker, bonytail chub, and Yuma Ridgway's rail.
