Today, House committee legislators will be voting to approve or deny a California irrigation bill that would forgive $375 million worth of debt owed by one of the nation’s largest farm-focused irrigation districts, Westlands Water District.

Approving the plan would, essentially, relieve the federal government of its obligation to provide drainage for each farm in the 600,000-acre Westlands district. According to The Sacramento Bee, the estimated overall costs to the federal government of providing these drainage services is $3.5 billion and counting.
