When the Indiana Territory was granted statehood (December 20, 1816), there were no settlers on the lands of the future Rush County. However, this changed quickly, and by 1821 the newly founded settlements were desirous of being organized into a county unit. Accordingly, the state legislature passed an act dated December 31, 1821, which authorized Rush County, effective April 1, and further authorized the first commissioners (pro tem) to begin organizing the county's governing structure on June 3, 1822. The act also authorized six townships to cover the county; subsequent growth through the years has caused the number of townships to double.[3] It was named for Dr.Benjamin Rush, one of the signers of the 1776Declaration of Independence.[4] That same summer (1822) the future town (and county seat) ofRushville was platted and laid out.
In the 1820s the low rolling hills of Rush County were generously covered with trees, usually walnut and sugar maples. By 1879 Rush County was the state's largest producer of maple syrup.[5] However, logging and clearing for agriculture have completely removed the trees, except for stands in drainages, and the available land is completely devoted to agriculture or urban development.[6] TheBig Blue River drains the upper part of the county, flowing to the southwest. The Little Blue River flows southwest to drain the central part of the county, andFlatrock River flows south-southwest through the lower central part of the county.[7][8] The terrain's highest point (1,135 feet/346 m ASL) is an isolated rise at the county's east boundary, 1.4 miles (2.3 km) SSW ofGlenwood.[9]According to the 2010 census, the county has a total area of 408.46 square miles (1,057.9 km2), of which 408.12 square miles (1,057.0 km2) (or 99.92%) is land and 0.34 square miles (0.88 km2) (or 0.08%) is water.[10]
In recent years, average temperatures in Rushville have ranged from a low of 17 °F (−8 °C) in January to a high of 84 °F (29 °C) in July, although a record low of −28 °F (−33 °C) was recorded in January 1994 and a record high of 108 °F (42 °C) was recorded in July 1901. Average monthly precipitation ranged from 2.55 inches (65 mm) in February to 5.06 inches (129 mm) in May.[11]
