Water Rights
Since 1910, the Boulder and Left Hand Ditch Company has operated the two lakes, which are reservoirs used to store water for agriculture. Boulder and Left Hand Ditch Company still owns the rights to the water and Boulder County owns the land surrounding them.
Growing Gunbarrel
In the 1960s, thanks to the nearby IBM plant and other commercial attractions, the Gunbarrel residential area grew up around the lakes. The lakes have been central to the Gunbarrel community from the beginning.
