Recent grants and projects

• 2010/2011: Bureau of Reclamation grant for $54,546 to evaluate a third gravel addition site on the American River, and continue monitoring at previous sites.  This project provides funding for graduate and undergraduate field assistants.
• 2009/2010: Bureau of Reclamation grant for $45,543 to evaluate salmon spawning habitat at two gravel addition sites on the American River.
• 2008/2009: Bureau of Reclamation grant for $24,519 to monitor and evaluate a gravel addition project near Sailor Bar (lower American River).   Graduate and undergraduate students will assist with site evaluation before and after the gravel is emplaced.
• 2007/2008: Water Forum grant for $26,298 for Lower Sunrise side channel restoration.  CSUS faculty and students will team with the City of Sacramento, private consultants and the California Dept. of Fish and Game to monitor and evaluate a spawning gravel restoration project on the American River. 
• 2006/2007: Bureau of Reclamation Grant for $37,804 to complete a gravel budget for the Lower American River.  This project provided funding for a graduate student in the CSUS Geology Department.
• 2005/2006: Water Forum Grant for $15,799 to support substrate evaluation at the Lower American River Sunrise side channel project.  This project supported graduate and undergraduate students for summer field work at a proposed steelhead restoration site.
• 2005/2006: Bureau of Reclamation Grant for $99,864 to evaluate Lower American River Gravel Budget and Inter-gravel flow in spawning gravels. This project supported graduate and undergraduate students who refined permeability models based on heat flow, and began a gravel budget study of the Lower American River.
• 2004/2005: Bureau of Reclamation Grant for $97,390 supported graduate and undergraduate students in geology and chemistry.  Project involved habitat suitability of spawning gravels on the Lower American River.  Students measured field conditions and gravel mobility and their relationship to salmonid spawning.
• 2003/2004: Bureau of Reclamation Grant for $103,000 supported three graduate students and a chemistry technician to continue work on gravel assessment and salmon spawning habitat on the Lower American River.
• 2002/2003: Bureau of Reclamation Grant for $97,400 supported two graduate students to work on gravel assessment and salmon spawning habitat on the Lower American River.
• 1997-2000: NSF CCLI award for $105,000 allowed us to purchase new equipment and develop curriculum modules that relate to stream flow and water quality. This grant was awarded to Tim Horner and Kevin Cornwell, and had a duration of three years.
• 1996-1999: coauthor on $220,000 Grant from the W. M. Keck Foundation provided funding for "Hydrogeologic Instrumentation".
