Fish Studies and the Delta

     The media owners in California, and the Department of Water Resources like to keep the focus on the "fish vs farmer" conflicts, as they do endless studies to validate taking MORE water away from the Delta, even though its a well documented fact the monumental decline in native fish populations is directly attributed to the diversion of to much fresh water from the Delta.  It seems in the last 10 years at least 6 billion dollars have been spent on fish studies, and on planning new diversions off the Sacramento River, and new water conveyance routes that "might" allow native fish, like salmon, to still survive their annual migration through the Delta to spawn in their natural habitats in the Sierra streams above Sacramento.  Just look at the statistics of fish decline since California starting taking more water out of the Delta in the 1990's, assuming they could "reoperate" the Delta Cross Channel to avoid more fish kills.  Long story.  As of 2011, according to reports by the different fish agencies...salmon, smelt and other native species are still in decline and could go extinct.  There are MANY agencies trying to fight additional water being exported from the Delta.  Other agencies promote use of the Yolo Bypass area for fish restoration experiments.  Other agencies promote restoration of the San Joaquin salmon runs by diversion of Sacramento River instead.  In other words, restore salmon runs on the San Joaquin by destroying salmon runs on the Sacramento River.  However, historically the salmon preferred the Sacramento River....just read it all for yourself.  Start with this description of the abundance of salmon in the Delta in the 1850':  http://www.yosemite.ca.us/library/scenes_of_wonder_and_curiosity/alabaster_cave.html which is an account of the writer's observations of fishing on the Sacramento River while on his way to the Alabaster Cave in the Sierra Foothills.  NOTE!  Below are maps from reports.  To see all the fish studies, please use the links to the left, by year.
