Are you talking about the water - lakes and ponds?  From reading  nmixter's
diary, he/she has posted comments about mapping farms.  One comment
suggested taking the import to the talk-us mailing list. BTW - I did just
drive through some farm land in Western Washington.  Farmers had dug
temporary canals to help drain (or so I assumed) the water from the field
so they could plant.  I probably wouldn't map it unless they were
permanent.
