| Relation | Central Utah Project; Western Waters Digital Library; this average IN concentration is more than two times annual average values for utah lake at the lake outlet since lampton lake would be filled in the winter when IN values are higher based on evaluations using trophic level correlation models larsenmercier Larsen Mercier and voller vollenweider velder weider seider the lake is predicted to be hypereutrophic hyper eutrophic A finite element model SRSWQ souris river study water quality a modified version of the well known WRE model showed that a fairly strong temperature stratification would develop in the lake during the summer and early fall months unless measures are taken to disrupt the latent stratification with stratification low oxygen conditions would develop at the bottom in waters deeper than about 25 feet disruption of the thermal stratification in lampton reservoir would be an important step in mitigating expected water quality problems three different methods have been preliminarily identified as helpful in disrupting the stratification and hence reducing oxygen depletion in the deeper waters 1 mechanical aeration air may be pumped into the bottom of the reservoir to add oxygen as well as to mix the waters various systems are available for aeration detailed engineering design studies would be needed to select the most effective in this case mixing not just oxygen addition is desired 2 lake drawdown by the midsummer and into early fall the thermocline will be at a depth of 9 to 10 meters with a full lake about 5070 50 of its area would be in the hypolimnion where oxygen depletion would be severe the lake would only need to be drawn down another 6 meters to reduce that value to 15 of the total area or in other words over 85 of the original lake would be in the mixed epilimnion actually with the 6 meter drawdown the lake surface area would be about 1200 acres and about 2550 2570 25 of that area would be below the thermocline 3 26 |
