Kaohsiung says its new flood pumps are working, but one part of Gushan still flooded — bad news for residents there, and the city blames an unfinished military project.

• Gushan's Taoziyuan side ditch overflowed even after the city upgraded a nearby pumping station.
• The city says the flooded spot sits in a different drainage area than the upgraded station, so the new pumps do not help it.
• The real bottleneck is a flood-holding project inside a military base that is not finished yet.
• Mobile pumps have been sent in as a stopgap while heavy rain continues.
• The city's detention ponds elsewhere filled to capacity three times in two days and still held back the peak flows.

Outlook: Flooding risk in that pocket of Gushan stays until the military base project is done, and the city is now studying extra pumping where the Gushan canal meets the Love River.
