Several tables were affeeted by ehanges to the report 
form seetions. Some tables that appeared in the 2008 
FRIS are not published in the 2013 FRIS, ineluding 
Chapter 1 tables 13, 24, 31, and 40 and Chapter 2 
tables 5, 6, and 7. Table 3 was updated to refleet 
ehanges that were made to the land use eategories in 
Seetion 2 of the FRIS report form; speeifieally the 
types of pasture - permanent, woodland pastured, 
and other pasture. The ehange was made to align 
FRIS with the 2012 eensus. 
The subirrigation method of water distribution for 
aeres in the open was not ineluded on the 2013 FRIS 
report form. This ehange affeeted Tables 28, 31, 32, 
and 39. The data for this method are now reported in 
the Other gravity item. In 2008 data were eolleeted 
for five eategories of Uneontrolled flooding and 
Other gravity methods and were published in Table 
7. Only data for the total aeres of eaeh of these 
eonveyanee systems were eolleeted and published in 
2013. 
Wells capable of being used, irrigation water 
transfers, and other uses of irrigation water are no 
longer published. Crops with small acreages have 
high variability because of the sample size. 
Sugarbeets, barley, and tobacco were removed as 
individual items in the field crops sections. 
Respondents reported these in the Other small grains 
or Other crops categories on the report form. 
Water management practices for gravity irrigation 
were combined into four categories in Table 39. 
DEFINITIONS AND EXPLANATIONS 
This section provides definitions and explanations of 
specific terms and phrases used on the reports forms 
or in the tables. Items in the publication tables that 
carry the note “see text” also are explained. 
Acre-feet of water. An acre-foot of water is the 
quantity of water required to cover one acre to a 
depth of one foot. This is equivalent to 43,560 cubic 
feet or 325,851 gallons. 
Acres and quantity harvested. If two or more 
crops were harvested from the same land during the 
year (double cropping), the acres were counted for 
each crop. Therefore, the total acres of all crops 
harvested generally exceeded the acres of cropland 
harvested. An exception to this procedure was hay 
crops.
