I have measured the spring's water temperature at 85-90 degrees and it is on an island about 100 feet from Clear Lake's western shore. During the Fall, when water levels are low, the spring is on level with the Lake. In other seasons, it may be submerged. US 101 to Hopland right on Hwy. Go across Hwy.
Spring is on western end of island nearer shore.
Indian Valley Reservoir. Golden and bald eagles nesting on on NW end of lake where Cache Creek comes in. Lake at about 1500' elevation. Spring to see eagles, Autumn for solitude. Summers are hot.
