Closed Basin Project Habitat Area. In this area the water table is very close to the surface. Water can evaporate directly from the soil or be taken up by plants such as salt grass, rabbit brush and greasewood, which release the water through evapotranspiration. The Closed Basin Project was authorized by Congress in 1972 to extract groundwater from the lowest part of the basin in an area that covers .
