Southern Sierra Fire and Hydroclimate Workshop

The first jointly scheduled Southern Sierra Fire and Yosemite Hydroclimate Workshop will be held April 22-24, 2014 in Yosemite Valley.  The workshop is focused on developing an integrated view of the physical landscape, climate effects, hydrology, and fire regimes of the Sierra Nevada.  This workshop was rescheduled from the original date back in October 2013 due to the federal government shutdown.  To register, visit the California Fire Science Consortium website.

New USGS Ward's Ferry stream gage

The USGS has installed a new stream gage near Ward's Ferry Bridge, at the upstream end of Don Pedro Reservoir, to monitor Rim Fire-related water quality parameters.  The gage currently records stage, water temperature, conductance, turbidity, dissolved oxygen, and pH.  The gage is funded by Modesto and Turlock irrigation districts, and the SFPUC.

2011-2012 Yosemite "Looking Downstream" report available

Yosemite National Park's 2011-2012 update report for the "Looking Downstream" project is available for download in the library.  

Looking Downstream is a long-term interdisciplinary study designed to better understand the physical processes and ecology of the mainstem Tuolumne River between O’Shaughnessy Dam and the western boundary of Yosemite National Park, with a focus on the biologically diverse Poopenaut Valley.  The project provides critical information used to manage environmental water releases from O’Shaughnessy Dam.
