Since the canal is fed from the two oceans it links together, how can it dry up? I am puzzled.

Two ‘rising’ oceans, right?
Most of the Panama Canal is actually an inland lake and waterway in Panama. This lake is higher than sea level and the ships must be raised or lowered at each end via ‘locks.’
If the water level in the lake/waterway falls, it takes longer for the locks to fill with water and this affects the speed with which the locks can be operated.
