The January I readings were 108% of average, and are 18% <br />above last year's January I readings. The snowpack in the Little Snake River Basin, mostly in <br />Wyoming, is even higher at 133% of average. Whiie precipitation during October and December <br />was below average, November's precipitation was 167% of average, and was the highest <br />basinwide percentage in the state for that month. Water year totals are now at 100% of average <br />and is the highest water year percentage in the state. Runoff is forecast near average along most <br />of the Yampa River and slightly below average along the White River. With the best snowpack <br />conditions north of the Yampa River, most of those tributaries are forecast to produce above <br />average volumes this summer. <br />
