The Maryland Department of the Environment issued a drought warning for central Maryland Thursday.
The lack of precipitation so far in 2017 has led to lower-than-normal stream flows and groundwater levels.
During a drought warning, MDE increases oversight of water supply conditions and encourages citizens and businesses to voluntarily reduce their water usage.
The drought warning includes Baltimore, Carroll, Cecil, Frederick, Harford, Howard and Montgomery counties, except for areas served by the Baltimore City or Washington Suburban Sanitary Commission on public water systems.
A drought watch is in effect for the eastern shore, including Caroline, Dorchester, Kent, Queen Anne's, Somerset, Talbot, Wicomico and Worcester counties.
Baltimore City and Washington Suburban Sanitary Commission public water systems have significant water reserves remain within normal ranges.
Information on current conditions can be found at the MDE's website.
