Jack London LakeIn 1913 the dam was constructed, and by 1916 visitors hiking half a mile from London's cottage came upon a four acre lake, with boardwalk, boat house and barbeque. Fishing, horseback riding, hiking and swimming were part of London's ranch lifestyle, and guests at his Beauty Ranch enjoyed this mini-bohemian grove long after London himself had passed away.

Today the dam is cracked and leaking, the lake is clogged with sediment and marshy plants and erosion downstream affect the entire Sonoma Creek watershed. An estimated one million dollars may be needed to repair the dam, dredge the lake, and repair the riparian areas.

We are raising funds, both through private donation and through state and federal grants. We have raised more than $175,000 to date, funding the engineering studies, site surveys, CEQA review, red legged frog survey, mortar studies and portions of the archeological review. The Historic Structures Report, also required, was funded by the Department of Parks and Recreation. Private funding is critical to our success, as we must provide matching funds for some of the grants we are currently hoping to secure.

The dam, lake and boathouse, all on London's Beauty Ranch, were added to the California State Park in the late 1980's. At that time a poorly conceived storm water outlet was installed as a temporary solution to the silted in lake. This resulted in tremendous erosion scouring a deep gully, twelve feet deep and twelve feet wide, decommissioning what is an important fire road. For thirty years the lake has been listed as an important deferred maintenance project but no funds were directed to the project and now the park is no longer managed by California State Parks. Valley of the Moon Natural History Association is the fiscal sponsor of the lake restoration and is also the non-profit operating Jack London State Historic Park for the coming five years.

Working together, private donors and state and federal agencies will save Jack’s Lake!

JACK LONDON LAKE ALLIANCE is a special project of VALLEY OF THE MOON NATURAL HISTORY ASSOCIATION. VMNHA is the cooperating association for Annadel, Sugarloaf Ridge and Jack London Historic state parks. We are an all-volunteer group of 400+ members and docents dedicated to assisting the Department of Parks and Recreation with interpretation, preservation and funding of special projects within the three state parks.

Mission Statement
JLLA formed with one objective: to fully restore Jack's lake, dam, dock, and surrounding landscape to the refreshing oasis it once was.
