At
http://tinyurl.com/5jpd4 there is an 18-page PDF of a technical study of
water availability in the Monocacy River watershed, which lies east of the Blue
Ridge divide in Maryland and Pennsylvania. The second and third sentences of
the document state:
"This drainage area includes significant portions of Frederick County, Maryland;
Carroll County, Maryland; and Adams County, Pennsylvania. It also includes a
small portion of Montgomery County, Maryland; a very small portion of Washington
County, Maryland; and Franklin County, Pennsylvania."
That "very small portion of Washington County" proves that the
Frederick-Washington boundary must necessarily stray east of the actual drainage
divide. A watershed map on page 3 of the PDF shows such deviation at the
boundary's north end as it reaches its tripoint with Pennsylvania. This
probably somehow accounts for the discrepancy that you noted on the USGS map.
Washington County was created from Frederick County in 1776, and their common
boundary was surveyed in 1824. Field notes of the survey are listed in the
on-line catalog of the Maryland State Archives.
