At the mouths of the rivers the fresh water tends to flow over the top of the salt water* This can be taken cnre of by means of submerged gates equipped with check valves to allow the passage of water from the lower strata* The whole process v_ can be further accelerated by the use of pumps taking the salt water out from the side of the dikes to be freshened• As the total annual intake is now several times the amount of water now in the reservoir site in the oase of either project, and a 50^ dilution occurs with each replacement, It is easy to see that freshening can be accomplished in a very few years* Numerous samples and drillings from the bottom of the Eastern portion of the lake and the flats to the East show that there are no deposits of precipitated salts which would re- dissolve in case of freshening• • 10 - |
