Nevada had its fifth-wettest October on record but 25% of the state remains in Exceptional Drought. Low reservoir levels have led to a decrease in hydroelectric power production. Drought conditions have not changed over the month.
Drought impact reporter scientists report low oxygen and high river water temperatures affecting fish. Some farmers delayed planting.
Meteorologists with drought.gov forecast drier than normal for the Southwest but wetter than normal for the Pacific Northwest and northern Rockies.
The U.S. Drought Monitor collects data from local observers, state climatologists, National Weather Service and hydrologists to analyze drought conditions.
