'The snowpack measurements in the Upper Rio Grande Basin <br />are up to 106% of average, which is the highest percent of average on February 1 since 1997. <br />There is 81 % more snow than there was last year at this time. Measurements range from only <br />73% of average in the Culebra and Trinchera Creek watersheds, to 123% of average in the <br />Alamosa Creek Watershed. The precipitation during January was a much appreciated 115% of <br />average, and the water year total is now 141 % of average. Reservoir storage in the six major <br />reservoirs combined remains extremely low at only 40% of average, which is only 67% of last <br />year's storage. Hopefully, the above average snowpack will continue into the runoff season to <br />help provide much needed additional storage. Streamflow forecasts are extremely variable <br />depending on location and snowpack conditions. They range from only 66% of average at the <br />Inflow to Costilla Reservoir, to 114% of average on the South Fork Rio Grande at South Fork. <br />
