This linear feature is approximately 180 feet long by 10 feet wide.

This feature is approximately 530 feet long and 10 feet wide.

The perpendicular side of this feature to the shoreline is approximately over 1,000 feet long.  The line parallel to the shore is approximately 770 feet long.  It varies in width from approximately 20-30 feet.  Directly to the North of this feature is another linear feature that is stretching perpendicular from the shoreline into the water.

This feature is approximately 285 feet on one side and approximately 285 feet on the opposite side and 30 feet wide.
