For all the water saving tactics San Diego County residents have employed, they’re not helping nature take care of her own. This photograph, taken the morning of Oct. 7, shows all too acutely what drought means to Fallbrook. This is what’s left of the man-made pond in Los Jilgueros Preserve. Acquired by the Fallbrook Land Conservancy in 1990, plentiful rains once filled the preserve pond so that water flowed from it across a concrete dip in the major trail through the interior, making the trail nearly impassable.
