<br />20 Under project conditions, considering (mly a .>ne t"J one salt
<br />balance, the TDS will increasE: irl th'C. ~'~"it2 Riv2r near Watson from
<br />439 mg/l to 469 mg/l; in the v"''''Pb River at Maybell, Colorado, from
<br />139 mg/l to 140 mg/l; bnd the Green Riv~r near Ouray, Utah, from
<br />392 mg/l to 396 mg/L When leaching .,f natLv" ""Its from irrigated
<br />lands is considered, in addition tc, tice _'ne C"",n" salt balance, the
<br />TDS will increase in th," Whit" River n2ar Wds,:,n, Utah, from 439 mg/l
<br />to 533 mg/l; in the Yampd Riv'2r oCt MoCyocll, C"lerado, from 139 mg/l
<br />to 147 mg/l; and in the Gr2en Rivd 'L~.r (1'lra\', L'tan, from 392 mg/l
<br />to 405 mg/L
<br />
<br />3. Since hardness is a const itu",nt of IDS, t,,," h"rdnceBs in the White
<br />River at RangE:ly, Coi"~)r6.d,) is 6.1s('1 E-xpect2d t~~, increase~ Under a
<br />one to one salt balance the hardness increase will be 14 mg/l as
<br />CaC03 and result in a present "mnuetl damage; L Rangely residents of
<br />$400 a year and of $1,000 in t,h2 year 2065. When leaching of native
<br />salts is considered, in additicn t:) tn." em" t:) one salt balance, the
<br />hardness increase is projected to be 4:l mg/l as CaC03. This increase
<br />will cause present damages of $l.JOO a year and $3,400 a year in 2065.
<br />
<br />4. By excluding the mineralized flow fru:n M22k'cr Spring, the reduction
<br />in the TDS loading to surfacc' waters in th" project area would be
<br />58,000 tons per year. This reduction in dissc,lved solids approxi-
<br />mates the total projected TDS loading fe.'ll the Project resulting from
<br />the leaching of native salts. However. due to the water loss caused
<br />by the Yellow Jacket Project, a J mg/l increase in c0ncentration at
<br />Ouray, Utah, is projected for thes" cundlt[c,ns. With the exclusion
<br />of the spring, an 11 mg/l rleduc t L,,, in bardne;s is expec ted at
<br />Rangely, Colorado, which would be' " sc.vings of $300 a year in 1965
<br />and $900 a year in 2065 to tbe resid'.,'nts (,f t',c area.
<br />
<br />5. With adequate wast" treatm<,:nt faciliti<e's Lor the towns of Meeker,
<br />Craig, and Steamboat Springs, postproj"c t s t [,,'amflows are sufficient
<br />to assimilate the projected waste lo"ds frc,'!! those population centers.
<br />
<br />6. Based on information available" no need is f,.JIeseen at this time for
<br />inclusion of storage in the project res,"rvc,irs for regulation of
<br />streamflow for the purpose af water quality contr'ol.
