California’s Salton Sea and state-straddling Lake Tahoe would receive funding for environmental restoration under a bill set for Senate approval Thursday. More controversial water-related efforts remain stuck in Capitol Hill limbo, however. Put simply, California’s diverse water ambitions face a complicated future in what remains of the 114th Congress. Showing some progress, senators have groomed a bill that includes a 10-year, $415 million Lake Tahoe restoration package. The broader water resources development bill also authorizes help for the endangered Salton Sea, the much-diminished Los Angeles River and Sacramento-area flood control, among other projects.
