The Salton Sea in California is actually a salty inland lake. The level of salt in the lake's water—what scientists call its salinity—has been increasing steadily for years because the lake's water is evaporating faster than it is being replaced by rainfall or rivers. If the trend continues, the lake's water will soon become so salty that the lake will be unable to support fish and bird populations. The lake would then become essentially a dead zone. Fortunately, there are several ways to reverse the trend that is threatening the lake's health.
One option is direct removal of salt from the lake's water in special desalination facilities. Water from the lake would be pumped into the facilities and heated. This would cause the water to evaporate into steam, while salt and other materials dissolved in the water would be left behind. The steam would then be cooled down and returned to the lake as salt-free water. Gradually, the high salt levels would be reduced and the lake’s overall health would be restored.
Another possible solution is to dilute the salt level in the lake with water from the ocean. Since water in the Pacific Ocean is 20 percent less salty than water in the lake, bringing ocean water into the lake would decrease the lake’s salinity. The ocean water could be delivered through pipelines or canals.
Yet another solution would be to control the lake's salinity by constructing walls to divide the lake into several sections. In the smaller sections, salinity would be allowed to increase. However, in the main and largest section, salinity would be reduced and controlled by, among other things, directing all the freshwater from small rivers in the area to flow into that main section of the lake.

The reading and lecture are both about the methods to reduce the salinity of salty inland lake, which otherwise would become a dead zone. While reading mentions three methods to reduce salinity, the lecturer suggests that these methods are not practical.
First of all, the author points out that direct removal of salt from lake water through the process of evaporation is one solution. The lecturer challenges this point. She says that there are several risks in this procedure.The evaporated residue often contains harmful chemicals such as selenium along with salt. Furthermore, she mentions that these chemicals can reach the people through air they breathe which can cause serious health risk.
Secondly, the author mentions that diluting the salt level in lake with water from ocean is another way to solve the problem. The lecturer finds flaws in this method as well. She rebuts this solution by stating that it requires construction of pipelines and canals which can cost a lot of money, and the local government will not be able to provide necessary support. She elaborates on this by mentioning that as the pacific ocean is about a hundred kilometers away, it may costs a huge amount of money for making canals or pipelines.
Thirdly, the author mentions that dividing the lake into several sections is also a great solution to control salinity. The lecturer, on the other hand, posits that the geographical activities like earthquakes can cause defects to these walls of separation. She puts forth the idea that even though the walls may sustain for a short while, they may eventually collapse due to the impact of earthquakes and cause the water to mix up from smaller sections to main and large sections.
