I I -4- Enbanced Snowpack Assessment (SNODAS) . The CWCB and the USBR are collaborating on the "Enhanced Snowpack Assessment" Project that uses modeled snowpack from the Snow Data Assimilation Systetn (SNODAS) and tailors model output to lKm resolution for Colorado's eight major river basins. The project u~es the USGS eight digit Hydrologic Unit Code (HUe) basins to then create sub-basin data. The two major goals ar~ to 1) develop quantitative snowpack numbers, and 2) link modeled snowpack to hydrologic models for strearhflow forecasts. I , Current online mapping products are: II . SWE & Basin average SWE I . SWE Change & Basin average SWE chan~e . Snow depth & Basin average Snow depth i . 24 hour snowmelt & Basin average 24 hour snowmelt I . 24 hour snowpack temperature & 24 hour snowpack temperature average I I Please note: SNODAS calculations account for the entire area of a basin and are not just an average of all of the SNOTEL sites near the basin. Therefore, basin ave~ages compute to much less than NRCS basin averages and are potentially more meaningful for assessing the conditions within the entire basin. I Dailv Statewide Flood Outlook , The CWCB is contracting to provide a daily Flood Threat Bulletin, which was a new service in 2006 operated as a pilot program and created due to feedback from local users following the 2005 runoff season. The CWCB Flood Threat Bulletin (ITB) provides a simple but accurate estimate of the flooding threat facing Colorado counties on a daily basis with a basin-specific forecast daily, and ~ twice weekly medium-range outlook. The service will indicate which areas of the state are at risk of flooding during a particular day and in upcoming days. The service is coordinated with the national Weather Service ForeJast Offices in Boulder, Pueblo and Grand Junction. This . service currently runs from May 1 to September 30, !which will include the spring runoff season, the summer I thunderstorm season, and the early fall monsoon sea~on. Feedback from the first season pilot program was very positive. During its peak in August, the website that disseminated the information logged over 7,000 hits; with users ranging from local floodplain managers and emergency managers, the media, the public, and oth~ state and federal agencies. I A continuous link to the FTB will be posted on the CWCB website, and the ITB will also be distributed this year via email to interested users. CWCB staff are curren~ly soliciting suggestions and feedback regarding content and format of the ITB so that it will have maximum usefulness to the end user. I I Staff believes that this service assists the CWCB with addressing its mission, goals and statutory requirements related to the prevention of flood damages in Colorado. Dailv Statewide Storm Precipitation Maps and Rainfall Reconstruction The Statewide Storm Precipitation (STP) Map is a sd-vice that involves the merging of the daily Storm Total Precipitation fields from the NWS WSR-88D Doppler radars from Denver, Pueblo and Grand Junction, Colorado and Cheyenne, Wyoming into a statewide radar estir$ted precipitation map. A brief discussion of the observed rainfall and flooding events depicted by radar will be iincluded. The purpose of this product is forensic in nature; while it does nothing to mitigate an actual event, it wi,ll aid in the identification, documentation, and response to rain-induced flood events that do occur. The STP Map is designed to show heavy rainfall in a spatial setting so that activities to respond to flood events can I be greatly accelerated. The maps are produced on a dflily basis from May through September. The STP map will be made available on a daily basis by 9AM and placed in the CWCB flood information web page. . Flood Protection.
