Two places on this list straddle county lines. Cascade sits mostly in Dubuque County but its
\nsouth side reaches into Jones County, so its 2,386 residents include some Jones County addresses.
\nZwingle runs the same way into Jackson County to the south. A third pair is easy to confuse on the
\npage alone: Balltown, an incorporated city on the Great River Road, is a separate place from Old
\nBalltown, an unincorporated hamlet nearby that predates it.<\/p>\n

Townships<\/h2>\n

Dubuque County is divided into 18 civil townships, which still run cemeteries, township roads
\nand local elections in Iowa even where a city has since taken over most services. Four have a
\nrecorded population, all from the 2000 census, the last year the county reported township-level
\nfigures separately: Center Township — covering Asbury, Centralia and Graf plus the hamlets
\nof Budd, Five Points, Lattnerville, Lore and Twin Springs — had 1,726 residents; Dodge
\nTownship — covering Worthington and parts of Dyersville and Farley — had 1,204;
\nCascade Township — covering part of the city of Cascade — had 1,079; and Concord
\nTownship — covering Holy Cross, part of Rickardsville and the hamlet of Cottage Hill —
\nhad 830. The other 14 townships — Dubuque, Iowa, Jefferson, Julien, Liberty, Mosalem, New
\nWine, Peru, Prairie Creek, Table Mound, Taylor, Vernon, Washington and Whitewater — carry no
\nseparately reported population and are mostly farmland between the incorporated cities.<\/p>\n
