Geography of Monroe County

Monroe County covers about 411 square miles. Most of this area (about 394 square miles) is land. The rest (about 16 square miles) is water. The land has gentle, rolling hills. These hills are covered with plants and are used for farming or city areas. The eastern part of the county has many small valleys and streams that lead to Griffy Lake. The highest point in the county is McGuire Benchmark, which is about 994 feet above sea level.

Neighboring Counties

Monroe County shares its borders with several other counties:

Lakes and Rivers

Monroe County has water flowing into two main river systems. These are the East Fork and West Fork of Indiana's White River. Water in the northern part of the county flows to the West Fork. Water in the southern part flows to the East Fork, mostly through Salt Creek and its smaller streams. One of these is Clear Creek, which is also known as the "Jordan River" on the Indiana University Bloomington campus.

Several artificial lakes have been built by damming creeks in the county.

  • Monroe Lake is the largest. It is a big lake on Salt Creek in the southeastern part of the county. People use it for fun activities like boating and fishing. It also provides drinking water for the city.
  • Lake Lemon was built in 1953. It used to be the main water source until the late 1960s. Now, it is a backup water source and is mostly used for recreation.
  • Griffy Lake is the third largest. It was built in 1924 by damming Griffy Creek. It was Bloomington's main water source until 1954. Now, it is mainly used for recreation. It can also be used for water in emergencies. In 2012–2013, the lake was drained to fix the dam, and then it was refilled.
  • Weimer Lake (also called Wapehani) was built for water supply. For most of its history, it was used for recreation, mainly fishing. In 2017, plans were made to drain this lake permanently because it was not considered safe. This happened in the summer of 2018.

Limestone has been taken from quarries in Monroe County since 1826. Many old limestone quarries are now lakes surrounded by cliffs. You can see these in the 1979 movie Breaking Away.

Railways

Monroe County has a long history with trains. Today, the only active railway is the Indiana Rail Road. Its main line crosses the county from northeast to southwest. There are also smaller lines to some factories. There are no passenger trains for people to ride.

From 1854 to 2004, an important train line connected the Ohio River to Lake Michigan. This line went through towns like Stinesville, Ellettsville, Bloomington, Smithville, and Harrodsburg in Monroe County. The Monon Railroad operated it for a long time. The last passenger train service on this line was Amtrak's Floridian from 1972 to 1979. After 1979, Monroe County no longer had passenger train service. The line was used for freight until 2004. Now, large parts of it have been turned into trails for walking and biking.

Air Travel

  • Monroe County Airport is southwest of Bloomington. Around 1997, regular passenger flights to this airport stopped. Since then, it has only been used by smaller, private planes.
