In 2009 there were four scheduled Release days. Due to the lower snowpack this year Pacificorp has been forced to cut back the scheduled release days for 2010 to three. Kevin Lewis of Idaho Rivers United said "Pacificorp has been great to work with on the recreational releases for the Bear." Idaho Rivers United was instrumental in obtaining whitewater releases on the Bear when FERC reissued the license for the Grace Power Plant in 2003.
