5 Pick a point inside or outside the pond.
The following prompt is displayed:
Pond elevation <elevation>
dePth (ft) (eXit/Daylight/Elevation/dePth) <0.0000>:

Defining the Pond Bottom By
Using the Daylight Option in this
chapter.
The following prompt is displayed:
Slope-Grade/Slope/<1:1>:
7 Do one of the following to define the slope:
n
Type G for Grade and enter a grade value (e.g., 5.00).
n
Type S for Slope and enter a ratio (e.g., 20:1).
After you define the slope, the slope pattern is generated. For more information,
see Defining Pond Slopes.
The following prompts are displayed:
Slope: 20.0000:1, Grade: 5.0000%
Linear slopes attached to all vertices successfully.
Shape Pond - All? <Yes>:
8 Type Yes to import the pond contours, bottom polyline, and slope control lines
automatically, or type No to end the command.
If you choose to shape the pond, then the following prompt is displayed:
Close contour lines? Yes/No: <Yes>:
9 Type Yes to create closed contour lines, or type No to draw contours that skip
the last segment of the perimeter.
NOTE
If the Pond Contour Settings are set up to create both normal and
highlight contours, then the close contour lines prompt is displayed twice.
