In 1954, the mined out gravel pit filled with water and Lloyd S. Brannan converted it to a private recreational swimming and boating resort.  It is an outstanding example of a privately owned entertainment and recreational lake venue with associated buildings in the midst of the Metro-Denver area.  Lake Sangraco is significant in the area of Conservation and Reclamation as an outstanding model of the ability to convert and reclaim natural resources depleted by mining operations, exemplifying the ongoing functionality of mined resources.  Additionally, the main buildings are good examples of the Mid-Century Modern style as adapted to recreational buildings.  Character defining features of the style found at the Lake Sangraco and Boat Complex include low-pitched gabled roofs, tripartite windows with casement sashes, picture windows, cedar tongue-and-groove siding, and wide overhanging boxed eaves.
