Water surface elevations for large lakes and reservoirs use which representation?

Water surface elevations for large lakes and reservoirs use which representation?

• A. Elevations printed in black slanted type within the body and maximum depths in blue slanted type
• B. Red numbers near the shoreline
• C. Green italic letters outside the water body
• D. Blue bold numbers outside the water body

Answer: (A)

The labeling uses a clear map-reading convention: water surface elevations for large lakes and reservoirs are shown inside the lake area in black slanted numbers, while the maximum depths are shown in blue slanted numbers. This combination makes the water level easy to read at a glance and keeps depth information distinct from the surface level. Putting the elevations inside the water body keeps them directly tied to the water surface, and using blue for depths provides a quick visual cue that you’re reading a measurement of how deep the water can get. Other color placements or near-shore labels can be less intuitive or harder to distinguish from shoreline features, so this arrangement supports quick and accurate interpretation.
