FREDERICK, Md. (AP) — A Maryland city has asked residents to limit water use amid "historic flooding."

The Frederick News-Post reports that the city of Frederick issued a release Wednesday night alerting residents that the city's wastewater treatment plant was at risk of additional overflow. The release asks residents to curtail nonessential water use to avoid potential backups in collection lines and homes and preserve the ability to safely treat wastewater.

The city also advised staying clear of Carroll Creek near its confluence with the Monocacy River because of potential sewer overflows.
