Shallow spots in big lake

[tigerhead]

Some of the rocks are visible, but if the tide is really high many of them will be submerged. The red line in the attached pic marks the location of the old jetty. On the bottom left is the old river channel that's going out to the ship channel on the south end of the lake. If you come into the lake from the ship channel via the old river channel, you can pick up the west end of the old jetty there and see how it runs.
