The continuing drought is causing concern about operating the Wolf Creek Nuclear Power Plant.
Officials say the dwindling water levels of a reservoir used to cool the plant near Burlington do not pose any safety risk.
The Kansas Water Office projects the John Redmond Reservoir will be almost dry by November 1, if current weather patterns persist.
Wolf Creek officials say it would be difficult to operate the plant if the drought continues for the next several months.
The water office says the reservoir was about 75 percent full on August 1. But the office projects the lake will be at only 5 percent capacity by November 1.
