Some snowpack/streamflow/precip/temp data & predictions:

http://www.wcc.nrcs.usda.gov/ftpref/support/water/westwide/streamflow/wy2011/strm1101.gif - spring/summer streamflow forecasts
http://www.wcc.nrcs.usda.gov/ftpref/support/water/westwide/snowpack/wy2011/snow1101.gif - snowpack
http://www.wcc.nrcs.usda.gov/cgibin/westsnow.pl - historical snowpack data (nice to compare to current data)
http://www.cbrfc.noaa.gov/wsup/westwide/westwide.cgi
http://www.cpc.ncep.noaa.gov/products/expert_assessment/drought_assessment.shtml - drought assessment data
http://www.cpc.ncep.noaa.gov/products/predictions/90day/ - temperature/precipation probability maps

Probably shouldn't count snowflakes/raindrops before they fall, and things can change, but as of now it looks like there should be adequate water in the rivers for the fishies this year.
