<br />0473 <br /> <br />Combination System <br />A combination of existing and new facilities would probably be best <br />in order to make sure water is recharged at a time when it may be of <br />most use. If existing canals are diverting to capacity when recharge <br />water is available, the purpose is being defeated. Furthermore, water <br />tables are generally high (less than 10 feet) in these areas and <br /> <br />would hinder recharge operations. <br /> <br />Test areas I, II, and III lie at sufficient distances from the river <br />that drain-out from year to year is low and a certain amount of carrying <br />storage may be expected, and recharge may ,b~,' ~rie whenever available <br />water and canal capacity exists.
