The chart below shows the recent record low catch of Delta smelt in the recent early April Kodiak Trawl by the California Department of Fish and Wildlife.  Trawls at 40 locations in the estuary collected a single Delta smelt, the fewest ever collected.  This result is consistent with other recent surveys, including the 2014 Fall Midwater Trawl (lowest in the historical record), the late April 2015 Smelt Larva Survey and early April 20 mm Survey.  Delta smelt, once the most numerous species in the estuary, is now hovering on the brink of extinction.  Longfin smelt are not far behind.  Yet the State Water Board continues to weaken already inadequate criteria established to protect these and other species.
