CryptQ- <br />sporidium, nicknamed .crypto," <br />recently attraCted attention in Arizo- <br />na when the parasite was found in <br />Phot'nix's and Mesa's treated drinking <br />waur supplies. <br />The Phoenix water department <br />found minute specimens of crypto in <br />tests .at tWO w.lter-treatment plants <br />during the past three months. Fol. <br />low.up teSts of the same batch of <br />water found no traces of the parasite. <br />State officials say the slight tnces are <br />no cause for al.arm. <br />The low le....e\ occurrence of <br />crypto reported in Arizona does not <br />pose the serious health haurd that <br />the occurrence of the parasiu did in <br />Milwaukee and Las Vegas.

Bureau of Reclamation postponed a scheduled spring flood of the <br />Coloudo River below Glen Canyon Dam, to the disappointment of biologists <br />and river nit guides. The flood, which a biologist s.id was .to clean out the <br />system," .....ould have been created by high-volume releases from Glen Canyon <br />Dam. Conservationists worry what the postponement ponends. <br />Plans called for flood waters released from Glen Canyon Dam to pour <br />through 225 miles of Colorado River bed during late March or early April, <br />with a velocity unmatched since the high-water summer of 1984. The turbulent <br />waters of the scheduled flood were to repair conditions affected by the dam's <br />open.tion. <br />The surging waters were to scour the ri..-er bed, carrying beach sands <br />downstream for redeposit on depleted beaches. The restored beaches would <br />buff<=r Anasazi ruins along the river corridor. Also, the forceful waters .....ould <br />be replicating the flood en\-ironment in which native fish evolved, thus <br />improving their current spawning habitat. <br />The BuRec halted the scheduled flood saying it required more tim<= to study <br />the -effects of the beach habitat-building,- Although the agency insists the <br />flood is merely postponed, not cancelled. critics ch~e that the influence of the <br />conrmued or; JMgt 2 <br />
