Storage, however, will <br /> be drawn down to low levels in many reservoirs by late summer. <br /> Statewide precipitation for the month of April averaged 97% of normal <br /> with a high of 127% of average in the Arkansas basin and a low of 64% of <br /> average in the Colorado basin. Snowpack measured on June 1, 1990, was only <br /> 58% of average. Snowpack is lowest in the San Juan/Dolores basin at 34% of <br /> average and highest in the South Platte and Arkansas basins at 83% of <br /> average. Although June 1 snowpack was below normal , it is considerably better <br /> than conditions measured on June 1, 1989. In 1989, much of the state had an <br /> early runoff relative to this year. A late runoff is expected in the west and <br /> northwest sections of the state. A late runoff is typically beneficial as <br /> water supplies then become available during the period of highest demand. <br /> Streamflow forecasts across Colorado are only 61% of average. The lowest <br /> forecast is in the Gunnison and San Juan/Dolores basins at 45% of average and <br /> is highest in the South Platte basin at 85% of average. The Colorado Climate <br /> Center forecasts warmer and drier conditions for the month of June. <br /> Beginning next month this report will take on a different format. The <br /> report will attempt to deal with the needs of the general public in <br /> understanding water supply conditions in Colorado. Each Division Engineer <br /> will evaluate basinwide conditions, provide a 30 day outlook, identify <br /> administrative/management decisions affecting water supplies and water use, <br /> and address public use impacts. The objective of the newsletter will be to <br /> both inform and educate the public in these areas. <br /> Contact John Kaliszewski , Editor, at (303) 866-3581 if you have any <br /> questions or comments. <br />
