Clear Lake is a populated place located in Collin County, Texas, United States.

A distillery was constructed and run by the US government in 1884 on the shores of adjacent Clear Lake.

A few people were drawn to the area by the government project, and by 1890 the town of Clear Lake had been founded.

Clear Lake's population shrank significantly after Dallas shelved the project.

Despite being in the center of the Blackland Prairie, seasonal flooding in the area around Clear Lake devastated crops.
