Barbara Boxer has torpedoed more legislation than she’s helped pass during her four terms in the Senate. Before retiring for good (literally), the Bay Area Democrat is trying to sink a water bill that could provide modest relief to farmers in California’s parched Central Valley. Congress plans to vote this week on bipartisan legislation that would authorize a variety of water projects including port dredging, reservoirs, fish hatcheries, lake recreation and wetlands restoration. The package also includes $120 million to fix Flint, Michigan’s corroded pipes and other aging municipal water systems.
