 farmed wetland (FW), such as surface drains, ditches, etc.

1/ Number listed below refers to the number of times an individual wet 



area was identified on the ASCS slides. 

 2/ FWS National Wetland Inventory Map. 

 3/ Check weather information concerning the years wet areas appear on 



the slides. If wet areas appear only on above normal precipitation 



years, call area non-wetland. 



Some other situations that will occur and needs to be Interpreted from 

 available resources are as follows: 



I. Wetland determinations on non-cropland Cpasture, hayland, 

 woodland) where the soil is a named hydric map unit. For our purposes, we 

 will assume a wetland exists if the soil is a named hydric map unit and 

 the area is in pasture, woodland, or non-cropland. The area also needs to 

 be reviewed for any existing drainage that might Justify a prior converted 

 (PC) status. 



2. Wetland determinations on non-cropland (pasture, hayland, and 

 woodland) where the soil is a map unit with hydric inclusions. If an area 

 is identified by available NWI maps, we will assume the area is a 

 wetland. If there are no NWI wetlands Identified, we will review slides 

 of the area to determine If drowned-out areas or basins with water 

 standing are present and follow the previously mentioned wetland chart
