'Based on selected stations

The January 1 snow measurements in the South Platte Basin are only 73% of average, Although
this is 37% more snow than last year at this time, it is far from the amount needed to help pull the
basin out of drought conditions, If weather patterns improve for snow accumulation many
portions of the basin could easily reach above average amounts by April 1, Unfortunately some
portions, such as the Upper South Platte Watershed, which is currently only 59% of average, maj
be lucky to reach average conditions before the meltout begins, Precipitation was only 39% of
average for the month of December, and the water year total is only 87% of average, There has
been 37% morepreCipitation this water year compared to this time last water year. Reservoirs in
the basin have only 47% oftheir average storage for this time of year. There is only 61 % ofIast
year's storage amount The early runoff forecasts are much below average at this time, and only
significantly improved snowpack will allow them to improve, Forecasts range from only 48% of
average at the inflow to Antero Reservoir, to 71 % of average on the St Vrain Creek at Lyons,
