Nearly 100 years ago Jack London built a small dam at the foot of Sonoma Mountain, creating an idyllic respite for hikers, swimmers, and horseback riders. Today, the dam is in imminent danger of collapse, the lake has shrunk to one quarter of its original size, and the surface is covered in algae. The Alliance is ready to meet the significant challenges of this important project.

We need your help to save Jack's Lake.
