The basin -wide April 1 <br />snowpack measurements are at 76% of average, which is only 3% of average higher than last <br />month's measurements. The spotty coverage of snowfall has measurements ranging from only <br />40% of average in the Alamosa Creek Watershed, to 134% of average in the Culebra and <br />Trinchera Creek watersheds. Precipitation was 111% of average during March, and the water <br />year total is now 88% of average. Reservoirs in the basin contain only 61% of their average <br />storage amount for this time of year, which is only 80% of the storage amount there was last year <br />at this time. Most of the forecasts remain much below average, ranging from only 49% of <br />average at La Jara Creek near Capulin, to 70% of average at Saguache Creek near Saguache. As a <br />striking contrast, Culebra, Costilla and Trinchera creeks forecasts are near to above average. <br />
