2011 GR Report

ADULT AND JUVENILE STEELHEAD POPULATION
SURVEYS, GUALALA RIVER, CALIFORNIA, 2011

Sorry, there is no Annual Report and Appendix for 2011. Abundant rainfall throughout the spawning season precluded making enough surveys for any meaningful data analyses and conclusions. In short, it was a great year for the fish--but a bad one for biologists. Please click on one of the other years, 2001-2010.
