Crystal Lake is a city in McHenry County in the U.S. state of Illinois. Named after a lake 1.6 miles (2.6 km) southwest of the city's downtown, Crystal Lake is 45 miles northwest of Chicago. The population is 40,269 as of the 2020 Census, a 1.2% decrease from 2010. The town was first known as Crystal Ville. It was changed to Crystal Lake sometime before 1840. The area known today as downtown Crystal Lake was first called Dearborn and later, Nunda (pronounced locally as Nun-day), from an area in New York where many settlers originated. The village of Dearborn was founded in the 1850s after an extension of railroads through the area. The villages of Crystal Lake and Nunda were both incorporated in 1874. In 1908, the name of the village of Nunda changed its name to North Crystal Lake. Several attempts were made to consolidate the two villages, and finally, after much disagreement, the village was annexed to the Village ofCrystal Lake in 1914. In 1914, a consolidated city government was established. The city is part of the Chicago metropolitan area and is home to the University of Illinois at Urbana-Champaign and the Illinois Institute of Technology. It is located on the Illinois River, which runs through the center of the town. In 1835, Ziba S. Beardsley had come to the shores of the lake and commented that the "waters were as clear as crystal", thereby giving the lake its name.


Crystal Lake is the primary city name, but also Bull Valley, Prairie Grove are acceptable city names or spellings, Ridgefield on the other hand no longer accepted or obsolete and are no longer used as a designation. Crystal Lake traces its origin to two separate communities which were established in the 1800s. In 1835, Ziba S. Beardsley had come to the shores of the lake and commented that the "waters were as clear as crystal", thereby giving the lake its name. The area known today as downtown Crystal Lake was first called Dearborn and later, Nunda (pronounced locally as Nun-day), from an area in New York where many settlers originated. The village of Dearborn was founded in the 1850s after an extension of railroads through the area. The villages of Crystal Lake and Nunda were both incorporated in 1874. In 1908, the name of the village of Nunda changed its name to North Crystal Lake. Several attempts were made to consolidate the two villages, and finally, after much disagreement, the village was annexed to Crystal Lake in 1914, and a consolidated city government was established. The first train station was built in 1856, although it was pre-fabricated and shipped from Chicago on a flatcar. Much of the land was originally owned by two early settlers, Daniel Ellsworth and Simon S. Gates. Charles S. Dole purchased over 1,000 acres (4.0 km²) of land overlooking the lake. It was his dream to construct an elaborate estate that would reflect his position as a successful businessman. He built a three-story mansion with adjoining gardens and stables. European craftsmen were imported to lay parquet floors, fashion archways and carve interior wood work from black walnut trees grown on the property.
