Bodies of water 
Monroe County is divided between the basins of the East Fork and West Fork of Indiana's White River.  The southern part of the county drains to the East Fork, primarily via Salt Creek and its tributaries, such as Clear Creek (known as "Jordan River" on Indiana University Bloomington campus). The northern part drains to the West Fork.
Several artificial reservoirs have been constructed by damming the county's creeks. The largest of them is Lake Monroe, a large reservoir on the Salt Creek in the south-eastern part of the county, is used both for recreational purposes and to supply the city with drinking water. Until the late 1960s, the main source of water supply was the smaller Lake Lemon (constructed 1953), in the northeastern part of the county; now it's the backup water source, and is mainly used for recreation.
The third in order of size is Griffy Lake, on the northern slope of the county. Constructed in 1924 by damming Griffy Creek, it was Bloomington's main water source until 1954; now it is now primarily used recreationally, although there are arrangements for it to be used as an emergency water source as well. An even smaller Weimer (Wapehani) Lake in the Clear Creek basin was originally constructed for water supply purposes as well, but now is used purely for recreation (fishing).
