Glendale Fire Department officials have determined that an underground natural spring was serving as the water source for a $10-million marijuana crop that police seized Aug. 16 in the Verdugo Mountains.
That information is contrary to early reports that the growers were tapping city cisterns — set in the hills for use by firefighters in case of brush fires — to irrigate the grove, Sgt. Tom Propst said.
Officials inspected the four cisterns in the area and found no evidence that anyone had tampered with the water supply, he said.
