Thompson EIS for water marketing from Green Mountain Reservoir. He also managed the
preparation of a third party EIS for the U.S. Forest Service, Routt National Forest, and the
Bureau of Land Management, Kremmling Resource Area, for the proposed construction and
operation of a dam and reservoir on Rock Creek or Muddy Creek in Colorado. He has
managed large, controversial water resources projects for numerous Federal agencies,
including the Albuquerque, Mobile, Omaha, and San Francisco Districts of the Corps of
Engineers, the Federal Emergency Management Agency, the National Park Service, and the
U.S. Bureau of Reclamation Lower Missouri and lower Colorado Regions,

The Rock Creek/Muddy Creek, Green Mountain, and Ruedi projects have involved
responsibility for coordinating the activities of a multidisciplinary engineering and
environmental team in preparation of a series of hydrologic, hydraulic, and environmental
reports and documents dealing with water resources of the West Slope. The projects
resulted in development of hydrologic models for reservoir system operations, procedures
for applying channel maintenance flow concepts to Colorado high mountain stream,
Environmental Assessments, Biological Assessments, and Draft and Final EIS documents.
Dr. Lagasse supported the Bureau, the River District, and the Forest Service at numerous
scoping sessions and public hearings during these projects. Dr. Lagasse has extensive
related experience in management and scoping for projects dealing with complex and
controversial engineering and environmental issues, serving for two years as consultant to
the Environmental Improvement Division, State of New Mexico, in the areas of hydrology,
hydraulics, and geomorphology for a series of public hearings on criteria for management
and disposal of uranium tailings in New Mexico. Specific project experience relevant to
the proposed study includes:
