Thday; fishermen object to the <br />dam's fluctuations for its effects on one of <br />the greatest trout fisheries in America. But <br />the rainbow trout, a cold water fish was <br />introduced after the dam 's constru~tion <br />and survives there because of it ' <br />The great red muddy river, 'the <br />Colorado, used to be "too thick to drink <br />too chin to plow," according to autho; <br />Philip Fradkin, In the parlance of the ' <br />hydrologists, the pre-dam river nows had <br />wide seasonal variations In magnitude <br />sediment load, and temperature: <br />Thousands of cubic miles of rock have <br />washed from the Colorado Plateau into the <br />river, leaving the wonders of the South. <br />west and providing the sediment carried by <br />the river. <br />But today, the water that passes through <br />Glen Canyon Dam is clear and cold, 99.5 <br />percent free of the! pre--dam sediment <br />which will conoct in Lake Powell for ~ <br />estimated 700 years. Average annual peak <br />flow was reduced from 93,400 cubic feet <br />per second (cfs) to about 29,000 cfs during <br />the filling of lhe lake. The capaclry of the <br />generators is 31,500 cfs, and operators en- <br />deavor to route all flows through the <br />money-making powerplant. <br />According to the Department of Inter- <br />ior, "the change from wann, sediment- <br />laden water to cool, clear water has <br />ch~nged the aquatic food base in the river." <br />11l1s has been good for introduced trout <br />but debimen~ to native and endangered <br />fish species. In addition, managing for <br />peak power production results in daily <br />fluctuations between 1,000 to 31,500 cfs, <br />causing the river level to rise and Call by 7 <br />to I1lCfe than 13 feet, depending on the <br /> <br />width of the river and the-dlsiance <br />downstream from the 710 foot high dam <br />~e c~mulativeeffects ofthesechang~ <br />~ slgmfic~t, and from SOme points of <br />View, benefiCial. Lany Stevens author of <br />The Colorado River: A Guide Through the <br />Grand Canyon, says that "totally by acci- <br />denl, Glen ~yon'Dam has produced the <br />largest belt of nparian habitat in the South. <br />west An~ that ~ntribu~(m, biologically; <br />has been mcre(bble.

Today's daily double fluctuation <br />of high and low water is sawing away the <br />b:eaches along the shore. Before, seasonal <br />variations both eroded and redeposited <br />sand and gravel throughout th'e length of <br />th~ canyon. Now, with sediment being <br />Withheld by the dam, there, is little new <br />material to replenish the bars; <br />:Frof?, a recreationill viewpoint, ,the <br />result is fewer and smaller CamPgrounds <br />along the w~y.

Jack Dav;is, Super~n:t(:ndent, of <br />Grand C1Ulyon J~4ational Parie;' says, :'the <br />sand bars have already. been altered' <br />,they'l~ never be what they were before ~ <br />dam was built," <br />.

They sued, he says, because of <br />the e(fe~ts the dam was having on wildlife, <br />vegetallon, beaches and stream flows, ad- <br />ding "it was Ute most unnatural thing in the <br />world, in a place where nature is supposed <br />to be the most important." The case was <br />dismissed by an appellate court as not ripe <br />for judicial review, because the Depart. <br />ment, had not yet addressed whether to <br />apply NEPA. <br />In 1980. the Navajo Nation filed a <br />similar suit, on the grounds that no en- <br />vironmental impact statement had been <br />prepared for continuing operations of Glen <br />Canyon Dam. On appeal" Interior <br />responded that it had not conducted a Glen <br /> <br />Canyon IDS because comprehensivestudy <br />was about to be undertaken for the entire <br />Colorado River basin. The court accepted <br />Interior's argument <br />The following year, in 1981, the En- <br />vironmental Defense Fund sued to force <br />the cotnprehensive study. the Department <br />continued with the next stage of its <br />"bureaucratic shell game". as one environ- <br />mentalist put it, by asking the judge nol to <br />order a comprehensive study because it <br />was about to prepare a series of site-' <br />specific EIS's.
