lake is part of the Sanborn county park system, located just minutes
up Rt 9 from downtown Saratoga. The lake itself is about 300 yards
long and maybe 100 yards wide, depending on the time of the year.
I'm not sure if it's an official reservoir for drinking water but
it is apparently under some sort of management. The lake, or really
more a pond, is a favorite destination for me. I found it about 10
years ago while exploring the various parks in the Bay Area. The trailhead
is at the end of Sanborn Rd (there's another trailhead on the other
side but requires about a 1.5 mi hike to get to the lake) and the
lake is a short 0.5 mi (uphill) hike from the trailhead.
