periods of high recharge to storage reservoirs for release at a later
date when surface runoff is low, and exchanging various types of water
for direct diversions from a stream.

Another feature of augmentation plans is the use of alternate points of
diversion. In this way, surface water rights can be tied to and
diverted through one or more different structures, including wells.
By doing this, it is possible in some cases to enhance the priority of
a well by combining it with a more senior and reliable surface right.
This is an example of optimizing the combination of physical and legal
supply.

The major application of the augmentation plan is in the development of

a rel iable water supply for municipal or industrial use. In using water

rights that have historically been used for irrigation to provide a

municipal or industrial supply, special problems are sometimes

encountered. These problems derive from the concept that when a water

right is changed there must be no injury to junior appropriators and

from the fact that a municipal water supply, in particular, is a year-

round use and must be highly dependable.

To protect other appropriators on a stream it is generally necessary to

limit a change in use of an irrigation water right to the period of

time it was historically used beneficially. This means that it can

provide water only during the irrigation season and not during the

winter months. Water for winter use generally must be provided from

reservoir storage by obtaining a new appropriation or by exchange.

Because the major portion of domestic consumptive use is for lawn

irrigation, the need to compensate for stream depletions by a

municipal use is less in the winter than it is in the summer.
