Geography and Nature of Clinton County

Land and Water Features

According to the U.S. Census Bureau, Clinton County covers about 412 square miles (1,067 km²). Most of this area, about 409 square miles (1,060 km²), is land. The remaining 3.6 square miles (9.3 km²), or 0.9%, is water.

Most of the county is in the Little Miami River area. This means its rivers and streams flow into the Little Miami River. Only the far eastern parts flow into the Scioto River.

Flat Plains and Ice Age Clues

Clinton County is mostly flat or gently rolling. This area is known as till plains. Long ago, huge sheets of ice covered the northern two-thirds of the county. This happened during the Wisconsinan Ice Age. The southern part was covered by even older ice sheets during the Illinoian Ice Age. Because of these ice sheets, you can find many features left behind by glaciers. These include moraines (hills of rock and dirt) and kames (small hills of sand and gravel).

The land in the county is generally about 1,050 feet (320 meters) above sea level. Most areas don't change much from this height, usually by less than 200 feet (61 meters).

Clinton County has a humid continental climate. This means it has warm, humid summers and cold winters. It is one of the cooler and wetter counties in southern Ohio. However, the differences from other southern Ohio counties are usually small.

The county gets about 42 inches (1.1 meters) of precipitation each year. This includes about 30 inches (0.76 meters) of snow. In July, the average high temperatures are in the mid to upper 80s F (around 29-32°C). Temperatures above 90 F (32°C) are common. Lows are usually in the 60s F (around 16-20°C).
