March brought 78% of normal precipitation, but the cumulative effect of a dry winter leaves the water
year-to-date precipitation at 69% of average. Overall, the Salmon basin snowpack is 64% of average.
The Lemhi and Little Salmon basins have the highest snow percentages at 70% of normal, while the
South Fork and Middle Fork Salmon basins have the lowest at 60% of average. The main Salmon
River and its tributaries are only forecast for about 50% of average streamflow. Other years with a
similar snowpack to this year are 1987, 1988, 1990, 1992 and 1994. In these years, the Salmon River
at White Bird peaked between 25,000–35,000 cfs between May 1 and June 1. Water users and river
runners should expect similar streamflow patterns this year, unless a wet spring occurs like in May
2005 and June 2009. Peak flows on the Middle Fork will be low, possibly in the 4.0 foot range,
without the influence of rain. The river will return to the 2.0 foot gage height before July 1. Plan your
trips according to your boating skills. In other low snow years, rain generated peaks on the Middle
Fork have exceeded snow generated peak flows, so watch the spring weather to be safe. The Salmon
River will see a very long floating season with a short high water season.

The River of no Return quite possibly has a snowpack of no return as this February 1 is only 69% of normal overall. The SNOTEL sites in the basin would have to experience 150% of normal snow between now and April to reach the average seasonal peak, which usually occurs near the first of April.

I am sure things will get better as the 2010 winter moves on.
