<br />. Last year we saw around 100 severe weather days in the spring/summer 2002 and for the
<br />spring/summer 2003 we could see 200-400 events or more this summer. We rnve already seen an
<br />early tornado just before the March 17-202003 snowstonn,
<br />. May to June outlook looks quite wet statewide with the South Platte and Colorado River basins 20-
<br />30% above nonnal and others very near nonnal. Spring rains may bring Front Range flooding threat
<br />Colorado Springs to Fort Collins,
<br />. The summer monsoons look to be average but burn areas will face serious flash flooding and water
<br />quality issues by August.

<br />Division of Water Resources - Keith Vander Horst / Jack Byers
<br />The DWR puts out a summary and graphic report of conditions by river basin for every month at
<br />hup://water,state,co.us/pubs/swsi,asp, Southwest stream flow is supposed to be better than last year but well
<br />below normal. Jack Byers the Deputy State Engineer also wanted to warn us that on the water commissioners
<br />also see lingering affects of the drought and water supplies and stream flow in areas of Colorado are still
<br />below nonnal. He also warns that it will be 30-45 days before we have good reservoir storage numbers,
<br />There are 16 Million AF water generated each year and this year we are at 1.4 Million AF part ways through
<br />the water year, Mid July we will likely see reservoirs at their highest levels, It will take years to fill Blue
<br />Mesa Reservoir. This is similar to the concept of the meteorological drought ending but the hydrologic
<br />drought still continuing, He believes that is will take a few more years of average or above average
<br />precipitation for the states reservoirs to recover.

<br />Colorado Climate Center - Roger Pielke
<br />Roger Pielke' s PowerPoint presentation is posted on
<br />the CWCB website at
<br />hUp://cwcb,state,co.us/flood watch/, Additional
<br />climate graphs and data are available at
<br />hup:/ /cli mate. atmos. col ostate. eduJ
<br />
<br />Water Year Data - Using climate divisions defined by
<br />Dr. Klaus Wolter of NOAA's Climate Diagnostic
<br />Center in Boulder, the accumulated precipitation data
<br />are tracked for at least two weather observing sites in
<br />each division, Also plotted are the average accumulated
<br />precipitation, the wettest water year in the period of
<br />record, and the driest water year in the period of record,
<br />Averages are shown for the period 1971-2000 and for
<br />the entire period for which weather data is available for
<br />each site,

<br />US Geological Survey
<br />The USGS didn't present at this meeting but wanted all to know about the
<br />Drought Watch Web Site hUp://webserver.cLusgs.gov/drought/, This site is
<br />still being developed but has 23 sites that will graphically show minimum,
<br />average and 1946-2001 average for stream flow, There are also graphs for
<br />percent of year to date stream flow volume and real time stream flow,
<br />Thanks to the USGS for this new series of graphical data that will be helpful
<br />in the forecasting and assessment of Colorado's climate and weather for the
<br />Flood And Water Availability Task Force meetings,
