The time is near-future. For peripheral reasons, the United States and the people of Utah have just had it with the Great Salt Lake: everyone wants it empty. There is a justified need to use the basin of the 4,400 km2 of the basin; dry, it is not a dire emergency: the studies, environmental impact statements have been done, and they are ready to undertake detailed planning and implementation of this project.
How difficult would this be, and what could this country best use the salt water for in a way that is socially, environmentally or economically beneficial to help justify* the costs of the displacement?
Speculative near-future technology and science is acceptable. 'Difficulty' assessment need not include environmental and social mitigation measures, this will be conducted separately.
For reference, I plan to drain all the world's inland saltwater lakes and seas after this one. They will just get subsequently easier to implement.
*-Other than the one direct justification that they will use the basin for.
