Defining Ponds

NOTE
The option to delete the outflow file, <pond name>.pda, is available if you
used the Pond Outflow Design dialog box to design the pond inflow and
outflow structures.
When you select a pond to delete, some of the delete options are not available.
For example, when you define a pond from existing contours, you can only
choose to delete the pond file. If you define a pond by using the Pond Slopes
commands, more pond data is created, and, therefore, more of the pond
deletion options are available.
If you delete the pond contours, slope control lines, or bottom polyline, you
can recreate these elements by using the Shape Pond commands.
WARNING!
Be careful when choosing to delete the pond files or the pond rim
(perimeter). If you use the From File option to delete the pond .pda file,
you cannot use the Hydrology commands with the pond. The pond
perimeter stores the pond shape information, and if you delete the
perimeter, you will have to re-create the pond slope data.
