Estimated Salton Sea elevations identified on this Contour -235 ft msl (Approx. elevation in the 1950's) Other Owners map are from the IID's Salton Sea hydrologic model (SALSA2). The data shown may not agree with Contour -242 ft msl (Estimated elevation 2025) Torres Martinez Tribe those projected by similar models developed previously due to differences in parameters Bureau of Reclamation incorporated into model development. Rate of Contour -248 ft msl (Estimated elevation in 2035) Not Reclamatoin Managed (Withdrawn Not Managed by Reclamation) recession may vary from this estimate and is Bureau of Reclamation dependent on future use and environmental Contour -249 ft msl (Estimated elevation in 2065) Reclamation Withdrawn, Reclamation (Withdrawn and Managed by Reclamation) conditions.
