Figure 12 presents data from the same profile for mid-July. <br />In this figure the Gunnison River water levels have dropped <br />considerably while the northern floodplain ground and surface <br />waters have remained higher. The water conductivity across the <br />floodplain retains the great differences from the River, <br />especially at stations 6 and 19. This indicates that large pools <br />of groundwater exist under the floodplain that are not greatly <br />influenced by the low salt water of the Gunnison River. The <br />origin of these waters is either recharge from off-site, or <br />Gunnison River water slowly recharging these areas, but this <br />water is greatly modified chemically by evaporation. <br />4522- <br />as21- <br />_~ <br />N 4520 <br />N <br />v- <br />Z <br />~ 4519 <br />H <br />Q <br />W <br />W 4518 <br />w <br />1- <br />Q 4517 <br /> <br />4516 <br />4515 <br />-1500 <br />-1000 -500 0 500 1000 1500 2000 <br />.DISTANCE FROM GUNNISON RIVER (ft) <br />-30 <br />.. <br />N <br />-25 <br />U <br />N <br />..i <br />-20 <br />to <br />C <br />a <br />7 <br />-15 O <br />s <br />--- <br />>-- <br />-10 ~ <br />>_ <br />H <br />U <br />0 <br />-5 Z <br />O <br />U <br />0 <br />2500 <br />Figure 12.
