<br />. <br /> <br />. <br /> <br />. <br /> <br />.' <br /> <br />-2- <br /> <br />is slated for the July 2003 CWCB meeting in Pagosa Springs. Based on operator final reports CWCB <br />staff will create a statewide annual report on wintertime cloud seeding operations in Colorado. <br /> <br />Priority CWCB Staff Action Items <br /> <br />Creation of Web Ready Weather Modification GIS Maps <br />Approximately $5000 in operator fees were raised in FY 2003 and the funds are being used to work <br />with Denver Water Department, HDR Engineering, Inc. and the cloud seeding operators to develop <br />some base data through GJ.S. maps and databases of the precipitation in the target areas. The GIS and <br />web project will be completed this summer and will create web ready maps that will show generator <br />locations, reservoirs, streams, cities and towns. The maps will link to operator reports and time series <br />data of SNOTEL and Snowcourse sites inside the target areas. This effort is to try and develop the <br />base data with the best data available. Phase II of this project will also happen during the summer and <br />is designed to standardize the operator monthly reporting and end of year reporting to specified <br />formats. It is believed that operator reports and graphs all in the same format will strengthen the <br />analytical capabilities and input of data to the GIS databases. <br /> <br />$2 million in BOR funding through the Weather Damage Modification Program <br />Every year the BOR offers $2 million in funding to western states for operational programs and <br />scientific studies. This federal fiscal year North Dakota, Texas, California, Oklahoma, and Nevada <br />received approximately $400,000 per state. CWCB staff and director's will seek a meeting with <br />Bureau officials in Lakewood Colorado this summer to investigate the requirements and proposal <br />process for funding that is allocated in October of every year. Based on that meeting CWCB staff may <br />develop a priority list and proposal for FY 05 funding to assist drier watersheds in Colorado. A portion <br />of that funding may also be used to conduct scientific studies through the National Center for <br />Atmospheric Research, the National Oceanic Atmospheric Administration, the Desert Research <br />Institute or possibly Colorado State University. <br /> <br />Finalize Scope of Work - Climatological Assessment of Cloud Seeding in Colorado's Watersheds <br />CWCB applied for Severance Tax FY 04 funding for $35,000 to complete an assessment of 30 years <br />worth of storm data. This project is for all of the eight Colorado watersheds and will give totals <br />storms, seedable storms, and the cloud seeding window of opportunity for each winter season in <br />Colorado. What this study is designed to do is: (1) build a 30-year database of storm systems and analyze <br />their cloud seeding capability (2) help water agencies determine the appropriateness and effectiveness of <br />cloud seeding in their watersheds (3) further quantify the "cloud seeding window" concept to get and the <br />range of time and space when cloud seeding can be effective in a storm system. In affect a cloud seeding <br />operator should only be able to take credit for precipitation that fell during this window of opportunity and <br />not the whole storm system. This study will answer the question "If you wanted to cloud seed what did <br />you have to work with?" This project will have an independent meteorologist work with program <br />operators and the state to develop the historical storm data set for Colorado and analyze it. It will make a <br />rough determination of the utility of cloud seeding before a forecasted drought to prepare for drought. This <br />study will inventory and analyze wintertime storm systems for the 30-year period that Colorado has had a <br />weather modification permit program 1972-2002. There has been advances in satellite, weather and radar <br />data that will assist in a detailed analysis of storms systems for the appropriate conditions (cloud base <br />temperatures, dew points, wind speeds and cloud base water levels) that are known to be effective by <br />cloud seeding by ground based silver iodide generators. <br /> <br />Weather Modification Association - Technical Resources <br />Flood Protection.
