From HydroCAD®
Stormwater Modeling - Since 1986 ..... Swamp Modeling
(http://www.hydrocad.net/swamps.htm)
In order to allow for rainfall on the
surface of the wetland, this
area must also appear in the model as part of a subcatchment, or
perhaps as a
separate subcatchment. If the wetland is saturated
or inundated with water, a high Curve Number of 98-100 can be used to
represent
the negligible infiltration capability. A lower CN value may be
appropriate if the
wetland is not saturated, and still has some absorption capability.

From the New York
State Department of State Division of Coastal Resources:
(http://www.nyswaterfronts.com/final_draft_html/Tech_Report_HTM/Land_Cover/Application_LC.htm)
There are no curve numbers for water or
wetlands. Water and wetland
are 100% permeable and have a curve number of zero.
