Cream together butter and sugars. Beat in egg, water, and vanilla.
Mix flour, salt, and baking soda. Add to butter mixture.
Stir in oatmeal, raisins, and nuts. Drop by spoonfuls onto greased cookie sheets.
Bake at 350 degrees for 8-12 minutes. Let them cool on cookie sheet before removing.
You can substitute chocolate chips or dried cranberries for the raisins. I prefer pecans but walnuts will work.
