A Summary of Water Conservation Programs in Active Management Areas
This summary is intended to serve as a resource for municipal water providers
and other organizations wishing to begin or expand their water conservation
programs. It contains information about conservation services, education
programs, outreach, rate structures, incentive programs, ordinances, and more.
Purpose Of AMAs
The State’s Active Management Areas were established to
provide long-term management and conservation of their limited groundwater
supplies. In order to accomplish this the AMAs administer state laws, explore
ways of augmenting water supplies to meet future needs, and routinely work to
develop public policy in order to promote efficient use and an equitable
allocation of available water supplies.

Irrigation Non-Expansion Area Facts
 The 1980 Groundwater
Management Act established two Irrigation Non-Expansion Areas (INAs) - the
Joseph City INA and the Douglas INA. Since the law was passed, the Harquahala
area has also been designated an INA. When an area is designated as an INA, a
restriction is placed on increasing the number of irrigated acres in the area.
In the Joseph City and Douglas INAs land that was legally irrigated at any
time between January 1, 1975 and January 1,1980 may continue to be irrigated. In
the Harquahala INA, the period establishing the right to irrigate is January 6,
1976 to January 6, 1981.
There is one exception. If the Director of the Department of Water Resources
(DWR) finds that substantial capital investment was made for on-site irrigation
facilities or improvement of land for irrigation use, that land may be
irrigated. The investment must have been made during a specified period of time.
In the Joseph City and Douglas INAs, the investment must have occurred during
the twelve months before June 12, 1980. In the Harquahala INA any improvement
made during the five year period preceding January 6, 1981 is considered.
All landowners in the INAs should be aware of several important requirements
of the Groundwater Code.
Measuring Devices
All persons withdrawing groundwater from non-exempt wells within an INA must
use a measuring device and measuring method to record water use. An exception is
made for persons who withdrew 10 acre-feet or less for non-irrigation purposes
only. A non-exempt well has a pump capacity over 35 gallons per minute or
irrigates more than two acres.
Wells
The Code requires that all existing wells be registered with
the Department of Water Resources. The fee for well registration is $10.
Prior to drilling a new well or deepening an existing well, a
person must file a Notice of Intent to Drill with the Department. Forms are
available from the Department and must be accompanied by a $10 filing fee. Authority to
deepen an existing well or drill a new well will be valid for one year; after
that a new Notice of Intent must be filed. A driller licensed by the Department
must perform the work.
Annual Reports
The Groundwater Code requires that each person withdrawing groundwater from a
non-exempt well in an INA must file an annual report of groundwater withdrawals
by March 31 of each year. An annual report must be filed whether groundwater is
withdrawn for irrigation or non-irrigation purposes. However, if no water is
withdrawn during a particular calendar year, then it is not necessary to file an
annual report for that year.
Change of Ownership
Each person who owns a well must notify the Department of Water Resources of
any change in ownership of the well. Additionally,
forms
are available from the Department for changing ownership of a Notice of
Irrigation Authority.
Municipal Conservation Program -
Third Management Plan Review
The Department is currently
conducting an evaluation of the regulatory program for
large municipal water providers contained in the Third
Management Plan.
