For a long time now, the Salton Sea has been close to the bottom of the priority list when it comes to water allocations and this has placed the Sea in a very tight spot. We have discussed extensively the consequences of allowing the Sea to dry and the temporary solutions outlined under the QSA. It has been recognized by the many stakeholders that the Salton Sea needs help but not much has been done. The Salton Sea needs a long-term solution that could give it hope for a sustainable future. Given the current conditions of the Salton Sea and the implications of allowing it to dry, perhaps an ambitious solution would be to incorporate the Salton Sea into future revisions of regional water laws.

The primary issue at the Salton Sea is the declining water level due to reduced water inflows and excessive evaporative losses. The main consequence of this is an increase in salinity, which in turn creates a sequence of other complications. The increasing nutrient concentration causes a dense growth of phytoplankton and plant life which deprives the Sea of oxygen and causes massive fish die offs. As the fish die, many bird species find it difficult to survive. In addition, as the Sea dries it exposes playa, which releases dust containing dangerous chemical compounds buried at the bottom of the Sea from decades of agricultural runoff.
It is evident that the consequences of allowing the Salton Sea to dry are quite disastrous and that they affect the aesthetic and ecological integrity of the Sea. It might seem that the key to preventing the Salton Sea from drying up lies in simply increasing the amount of water that goes into the Sea, but where to get the water from? That is a question that is far from simple and one that might not have a reasonable answer.

Located in an extremely arid region, the Salton Sea is subject to high temperatures and low precipitation. Extreme evaporation alone causes the water level at the Sea to decrease 5.4 ft. every year . Historically, the majority of the water inflows at the Sea have been from diversions of the Colorado River, inputs from Mexico, and agricultural discharges from Imperial, Coachella, and Mexicali Valleys. Without these vital inflows, the depth of the Sea will quickly decrease causing release of contaminants currently present at the bottom of the lake and increase in salinity to even higher levels. The current salinity at the Sea is about 54 g/L which is much higher than the salinity in the ocean which is on average 35 g/L. This high level of salinity will affect the habitability for fish at the lake where only tilapia species have been able to survive despite massive die offs.
