IRRIGATION DISTRICT OPERATION AND FINANCE. 5 
The increasing- favor in which irrigation bonds have recently been 
held has been accompanied by a corresponding increase in the number 
of districts formed throughout the West. In the two years 1919 and 
1920 there were created 156 irrigation districts, or more than one- 
fourth of the total number formed to date. This activity has taken 
place mainly in California, Washington, Oregon, Idaho, and Montana.

formed. The symbols are not superimposed, the height of each column representing the total 
number of districts formed that year. 
The year 1921 showed a very marked decrease in the number of new 
districts organized, but on the other hand witnessed the sale of more 
bonds than any previous year. 
The accompanying chart (Fig. 2) shows the status on December 31, 
1921, of all irrigation districts organized to that date. Table 2 sum- 
marizes areas included in all irrigation districts in the several States.
