Imperial Valley’s water district, the Imperial Irrigation District, is demanding state water officials have a 10-year plan for the management of the Salton Sea by the end of the year or it will not agree to a proposed Colorado River drought deal. The Salton Sea is shrinking due to a water transfer deal that sends water to San Diego County and the Coachella Valley. As the lake recedes, wildlife habitat is being lost and playa, the lakebed, is exposed, causing a health hazard due to an increase of dust in the air.
