Cliff Hurley has a point about the shallow northern and southern ends of the Salton Sea being responsible for a large amount of evaporation relative to the volume of water stored there (I.V, Press, Monday).
Unfortunately, hydrologic balance is only one factor we need to consider when entertaining the idea of "eliminating" these areas.
These shallow water areas are the most productive parts of the sea with respect to the "little critters" so important as food for fish and birds. This has been documented by a team led by San Diego State University biologist Dr. Deborah Dexter in a soon-to-be-published study.
They found that during the warmer half of the year (May-November) abundance of the pileworm and other bottom-dwelling invertebrates was essentially zero at depths greater than 9 to 12 feet. During this time these invertebrates are prevented from occupying most of the sea's bottom because oxygen is lacking or in too low concentrations in deeper waters.
