<br />ACKNOWLEDGMENTS <br /> <br />Special recognition is herein given to Dr. J. Owen Rhea for his cooperation and work on this research <br />study. From February 1992 to February 1994, Dr. Rhea held a meteorologist position in the Water <br />Operations Branch of the Reclamation Mid-Pacific Region's Central Valley Operations Coordinating <br />Office, Sacramento, California. While working in this position, Dr. Rhea adapted his orographic <br />precipitation model to the American River Basin above Folsom Reservoir. He subsequently ran his <br />model for selected historical major storm periods and compared the model predicted precipitation with <br />recorded precipitation. Both predicted and recorded 6-h precipitation accumulations for the storms <br />were input to the HED71 hydrologic headwater runoff model; Dr. Rhea then compared predicted and <br />observed peak inflow values for Folsom Reservoir. During 1993, Dr. Rhea made the necessary <br />arrangements and developed procedures for obtaining prognostic gridded field data from the NMC <br />(National Meteorological Center). In February 1994, Dr. Rhea accepted a new position with the <br />California-Nevada River Forecast Center, where he serves as the senior HAS (hydrometeorological <br />analysis and support) forecaster. <br /> <br />Thanks is given to Mr. Timothy Barker ofthe National Weather Service's Scientific Services Division <br />in Salt Lake City, Utah, for providing software to extract NMC model prognostic data for selected grid <br />points, convert these data to ASCII, and store them for retrieval over INTERNET. <br /> <br />Special thanks is due to Mr. Chester Bowling, Chiefofthe Water Operations Branch, Central Valley <br />Project Water and Power Operations Office (formerly known as the Central Valley Operations <br />Coordinating Office), for providing the support that allowed Dr. Rhea to work on this study. Mr. <br />Bowling also provided valuable information on water operations for the Central Valley Project, and <br />critical areas where better flood potential forecasts are needed. <br /> <br />Thanks is also given to all of the Reclamation employees who took the time to complete and return <br />the Questionnaire on Meteorological Support. Special thanks is given to Gordon Aycock (GP-450) and <br />Susan Hoffman (MP-700), whose help in distributing the questionnaire resulted in the receipt of a <br />representative number of responses from their respective regions. Tom Hovland, Reclamation <br />Technical Communications Group, provided technical editing for this report. <br /> <br />u.s. Department of the Interior <br />Mission Statement <br /> <br />As the Nation's principal conservation agency, the Department of the <br />Interior has responsibility for most of our nationally-owned public <br />lands and natural resources. This includes fostering sound use of our <br />land and water resources; protecting our fish, wildlife, and biological <br />diversity; preserving the environmental and cultural values of our <br />national parks and historical places; and providing for the enjoyment <br />of life through outdoor recreation. The Department assesses our <br />energy and mineral resources and works to ensure that their <br />development is in the best interests of all our people by encouraging <br />stewardship and citizen participation in their care. The Department <br />also has a major responsibility for American. Indian reservation <br />communities and for people who live in island territories under U.S. <br />administration. <br /> <br />The information contained in this report regarding commercial <br />products or firms may not be used for advertising or promotional <br />purposes and is not to be construed as an endorsement of any <br />product or firm by the Bureau of Reclamation. <br /> <br />11 <br />
