I checked out the bars at 3rd at the -0.5 tide. The map at
http://sfports.wr.usgs.gov/cgi-bin/zoom_sb.cgi?x=172&y=227
still seems mostly accurate. The launch is at the yellow corner in
the lower left.

Notes:
    It shows the channel-edge bar going upwind from the 4th bridge
    support, but ending halfway to the marker. The bar does not end,
    but continues right up past the marker, gradually getting lower,
    with the lowest spot immediately upwind of the marker at around -1 ft.
    This bar comes back up to -0.5 to 0 ft about 200 yards upwind of
    the marker.

    At lowish tide, if you run out of wind, you can walk down this bar
    towards the leeward shore when the water is still too deep to walk
    straight to the launch. The construction folks have dredged
    out under the bridge for 100 feet, but you'll want
    to angle towards the shore before then anyway.

    Right next to the bridge, there is a 100-foot-wide beach in a
    shallow inside bend in the levee. The last exit ramp is on this
    beach, but beware of two rock fields imemdiately upwind of this
    beach! If the water is low enough to see the beach, you will
    probably hit the rocks (some are 2 feet above the bottom in this
    area).

    If you do go under the bridge, the water gets 1-2 feet shallower
    past the fishing pier. The best bottom for walking in appears
    to be under the power lines.

Recommended low-water sailing path: from the launch, go off the wind a
bit to avoid the leeward end of the bar 300 yards from shore. Then bear
upwind to pass the upper ends of the next three bars, passing just
upwind of the marker.
