| Relation | Central Utah Project; Western Waters Digital Library; 3 multiple depth outlets by drawing the water from near the bottom colder water the modeling showed the thermocline to be about 2 to 3 meters deeper by late summer than if a near surface outlet was used not only does this reduce the area in the stagnant bottom waters it also hastens the overturn and mixing of the waters by nearly a month in the fall one would have to withdraw quite selectively to discharge the cooler water near the bottom of the thermocline but yet avoid discharging the bottom waters if they were too low in oxygen construction of a multiple depth outlet structure with discharge of cooler water from the top of the hypolimnion during the summer and planning on a 6 to 10 meter drawdown by midsummer should mitigate most of the low oxygen problems in the lake if the problems were still viewed as too severe after a few years of operation an aeration system might be considered extreme drawdown in the late fall might be very detrimental during the occasional winter where a persistent ice cover forms on the lake under these conditions oxygen depletion might occur throughout much of the lake sedimentation of suspended solids in the relatively quiescent lake would likely remove light limitation as the limiting factor for algae and could lead to much heavier algal growth than in utah lake algae blooms at the surface and anoxic conditions at the bottom could combine to cause serious aesthetic recreational aquatic habitat and water quality problems careful management and control of these problems can greatly reduce their detrimental impacts although not completely eliminate them 3 26a |
