Mr. Randle has been with Reclamation for 22 years — nearly all of that time with the <br />Sedimentation and River Hydraulics Group. He has developed several computer models and <br />conducted geomorphic and hydraulic studies of many rivers throughout the western United <br />States. <br />He managed the interagency team that prepared the environmental impact statement (EIS) for <br />operations of Glen Canyon Dam. He also served as the team's sediment and river hydraulics <br />specialist. This EIS led to the test -flood release from Glen Canyon Dam that received nationwide <br />attention in March 1996. <br />Mr. Randle also worked on Elwha River Restoration Project, in Washington, which involves the <br />removal of two hydroelectric dams. He led an interagency group of sediment and hydraulic <br />specialists that developed and evaluated alternatives to manage the nearly 18 million yd of <br />sediment trapped behind the two dams. He also conducted a detailed study of the river erosion <br />alternative, which was later adopted as the preferred alternative. <br />Mr. Randle was named "Engineer of the Year" for 1997 by the Bureau of Reclamation and <br />honored as one of the top ten Federal Engineers by the National Society of Professional <br />Engineers. <br />Mr. Randle has conducted studies to document the geomorphic impacts from the 1976 failure of <br />Teton Dam and the proposed removal of Savage Rapids Dam on the Rouge River near Grants <br />Pass, Oregon. He is currently studying the geomorphic processes of several rivers on the <br />Olympic Peninsula of Washington State including the Hoh, Dungeness, and Quinault Rivers. <br />Mr. Randle has also been studying the Platte River in Nebraska since 1987. His most recent <br />work on the Platte River has been in support the current EIS. Mr. Randle can be contacted at <br />(303) 445 -2557. <br />Hydrology: <br />Mark Butler <br />Mr. Butler graduated from Colorado State University in 1978 with a bachelors degree in <br />Watershed Sciences. Mr. Butler was employed from 1987 to 2000 as the Service's Platte River <br />Hydrologist, and from 2000 to the present as Platte River Liaison between the Service and the <br />Platte River Program. Prior to the above, he was employed with the Bureau of Land <br />Management as Area Hydrologist in the Oklahoma Area Office (4 years strip mine hydrology), <br />and as District Hydrologist in the Roseburg District, Oregon (4 years forest hydrology). . <br />Mr. Butler can present information summarizing the hydrologic changes in the Platte River <br />system over the course of time and the effects of these changes on listed species habitats. He can <br />summarize the Service's 1994 Instream Flow Recommendations and discuss how those flow <br />values have been utilized by the Service in analyzing changes in water management and habitat. <br />
