*The Lake Norconian Club Historic district covers an area of approximately 75 acres and
consists of Lake Norconian and nine buildings and features listed on the National Register of
Historic Places. The preservation of the Lake Norconian Club historic district includes the
restoration, repair, and preservation of the existing buildings and elements within the district.
Lake Norconian is a 55-acre lake with a watershed of approximately 179 acres and
supports approximately 20 acres of wetlands. The lake is primarily recharged with piped water
maintained by the Navy. Lake Norconian's wildlife diversity consists of at least 126 bird
species, 8 species of reptiles and amphibians, 15 mammal species, and 6 fish species making
Lake Norconian a highly valued water refuge in the desert environment of Riverside County. In
addition, Lake Norconian serves as a winter resting spot for 160 species of migrating birds,
including sensitive, rare, and federally listed species. It is important that cultural resource
management and natural resource management issues on the installation are maintained
throughout the transition of the installation and it is incumbent on the Navy to maintain the
caretaker status until the Navy has properly turned over the property to a responsible party.
