PROVISIONAL DATA SUBJECT TO REVISION

Click to hidestation-specific text
Click for larger image LOCATION.--Lat 39°20'28.5", long 77°38'02.7", Frederick County, MD, Hydrologic Unit 02070008, on left bank, at downstream side of highway bridge on
Jefferson Pike and 0.9 mi northwest of Rosemont.
DRAINAGE AREA.--4.16 mi2, from automated delineation using 30-meter National Elevation Dataset, digital elevation model data, dated December 2011.
PERIOD OF RECORD.--October 2016 to current year.
GAGE.--Water-stage recorder, water quality monitor, crest-stage gage, and velocity meter. Datum of gage is 413.26 ft above North American Vertical Datum
of 1988. October 1, 2016 to January 18, 2019, at site 80 ft downstream on right bank at gage datum 2.0 ft higher. May 23, 2019 to present, at current location and datum.
REMARKS.--U.S. Geological Survey water-data telemeter at station.
COOPERATION.--Funding for the operation of this station is provided by the Maryland State Highway Administration and the U. S. Geological Survey.

Notice:
August 28 - December 17, 2018: The on-site velocity meter raised to avoid the migrating channel bed. During this period the sensor will only report
water velocity when gage height is greater than 2.1 feet.

This station managed by the MD-DE-DC Water Science Center Baltimore office.
