The cyan-colored area southwest of the reservoir on the left is a filtered, chlorinated public pool that features a man-made sand “beach” all along the arcing, 6-inch deep south edge. The “beach” is about 15 feet wide, at which northeastern edge the water is about 18 inches deep, then the regular plastered pool bottom continues to the northeastern edge, getting to a maximum depth of about 4 feet. A grassy slope flanks the entire pool along the southwest edge; it’s perfect for lounging and keeping watch as the kids splash and play to their hearts’ content in the pool.
The environs and the water are much more pleasant than the beaches, and this is FAR more easy to get to; it’s much closer than any of the ocean beaches north or south of S.F.
We have some nice beaches on lakes around here -- I just don't have time for them and I don't much like sunning anymore. (The latter could be improved a little if I reduced the available surface area...)
