APPLICATION FOR CHANGE OF WATER RIGHT
HISTORICAL WATER USE ADDENDUM
This addendum may be completed and the information attached to a change application. This addendum is for changes
to irrigation uses only.
Attach additional sheets if necessary. Attachments must be labeled as shown in the sections below (i.e. HUA.1.a). If a
section is not applicable, label the section as Not Applicable or NA and explain why it is not applicable.
If you would like the Department to consider a consumptive volume other than the amount that would be determined
through the use of ARM 36.12.1902(14), you must complete this form. Additional information may also be included to
justify your historical diverted volume. Include as much detail as possible for each water right. The answers to these
questions will allow the Department to analyze the extent of the historical consumptive use and whether the historical use
will be adequate to meet the needs of your proposed use.
Water Right No.
