The image is a schematic cross-section of a water body’s bottom contour, indicating a sloping bed from left to right. A cyan line marks the water surface, with vertical red arrows denoting depths to two key submerged features: green-colored weeds at 5 feet and a dark red stump at 12 feet. Labels identify “MAIN POINT AND SECONDARY POINTS” at the top, suggesting use in surveying or navigation planning.

Used in marine navigation guides, boating safety resources, or hydrographic training materials to illustrate depth referencing and hazard identification; matches user intent seeking visual aids for understanding underwater topography or preparing for shallow-water operations.
