January flows were average to well above average for about 75% of the nation's key index streams, but many flows had dropped sharply from the extremely wet conditions in December, according to the U.S. Geological Survey (USGS). USGS hydrologists said that record high flows for January were set at four stream sites in Wisconsin, Utah, Minnesota, and Alaska.

Of the 174 key index stream-gaging stations across the country, 31% (54 stations) reported well above average flows, 44% (76 stations) reported average flows, and 25% (44 stations) reported well below average flows. In both November and December, flows were average to well-above average at about 90% of the same index stations.
