<br />,,', The effect at "perial Dam in. the Lower aorado River Basin <br />was not mentioned. <br />Note: The Colorado River Basin Salinity Control Forum, rep- <br />resenting the seven States of the Colorado River Basin, several <br />years ago established a policy of "no return flow" from thermal- <br />electric generating stations. The statement in the draft EIS <br />that, "The cumulative effects of all developments and withdrawals <br />on the White River would increase salinity 13 mg/l (from 445 mg/l <br />to 458 mg/l) in the.year 2000 is vague and misleading. No location <br />at which the 13 mg/l increase is supposed to take place is desig- <br />nated. Therefore, since the figure 445 mg/l is used as the base <br />figure, it is assumed that the 13 mg/l increase is to take place <br />at the Watson gaging station. <br />If the withdrawal of water is to take place at the Bonanza <br />site - not far from the Watson gage - in the amount of 17,470 <br />acre-feet for the power plant and 1,565.6 acre-feet for the <br />Deserado Mine and slurry pipeline, there would be about 11,500 <br />tons of salt removed from the river annually. Under the "no <br />return flow" policy adopted by the seven basin States none of <br />this salt would be permitted to return to the river. The same <br />reasoning would apply to the withdrawal of water at the Rangely <br />site; although the tonnage of salt removed would be different. <br /> <br />..'" <br /> <br />Ground Water <br />In the Upper Colorado River Basin there is a lack of know- <br />ledge concerning the extent and quality of ground water aquifers <br />and ground-surface water relationships. <br />Three test wells drilled in the Moon Lake coal lease area i. <br />showed large drawdowns with very low pumping rates. Only one test <br />well showed a specific capacity in excess of one gallon per minute <br />per foot of drawdown, which is in the lower limits for a low <br />capacity rated well. TDS were 3,240 mg per liter. The conclu- <br />sion is that the quantity of ground water is low, and the quality <br />is poor. <br /> <br />Endangered or Threatened Fish <br />The reach of the White River that could be affected by water <br /> <br />0310 . 0 U) <br />'J.!-' <br />( <br />
