The city of Crystal Lake is located in McHenry County, on the northwestern edge of the 6th Congressional District. It is the largest city in McHenry County, with a population of more than 40,000. The city takes its name from the large lake just southwest of downtown, where, in the 1900s, ice was harvested and shipped by rail to Chicago.


Living in Crystal Lake

Crystal Lake’s Community High School District 155 contains four high schools, in addition to the city’s ten elementary schools and four middle schools.

Historically, Crystal Lake was known for American Terra Cotta Tile in the late 19th century, and TECO art pottery invented there. Today, there is access to Chicago from Crystal Lake via the Metra Rail Union Pacific Northwest Line, providing residents with an easy commute downtown.
