FORT WORTH, Texas (AP) — The Texas drought has left a lake too low to keep supplying water to nearly a dozen Panhandle cities.The Canadian River Municipal Water Authority near Amarillo voted Wednesday to stop using Lake Meredith after four decades.This year water was pumped only from June through August instead of year-round — the first time that's been done.The authority's general manager, Kent Satterwhite, says water levels dropped to a record low — just under 31 feet — because of the historic drought.But he says the water authority's half a million customers won't notice the absence of Lake Meredith's water supply until next summer at the earliest. That's when water usage is highest.The authority's remaining water source is one of the world's largest aquifers.
