U.S. lawmakers from California have more political turbulence ahead of them with the introduction Tuesday of a bill to settle a long-running San Joaquin Valley irrigation drainage dispute.

 

The legislation by Rep. David Valadao, R-Hanford, would implement a sweeping drainage settlement reached between the Obama administration and the Westlands Water District. It also reignites some of the same regional and partisan conflicts that have dogged past water bills.
