Worries that firefighters can't access an adequate supply of water to combat flames in Hawaii are rekindling a longstanding fight over stream diversions in Maui. The Hawaii Attorney General's office is pointing a finger at a recent court ruling that required more water be kept in local streams amid drought and competing demands for use. The dispute connects the current blazes to an earlier court battle that pit Hawaiian activists against landowners after decades of diverting water to sugar cane fields. The Sierra Club said Monday that the attorney general’s office had exaggerated the effect of water diversion caps on firefighting.
