Since 2017, some surveys collected no Delta smelt (Figures 1-3) in the San Francisco Bay-Delta estuary. The 2018 and 2019 survey catches (Figures 1 and 2) are a new low for Delta smelt, lower even than the 2017 survey catch (Figure 3), and the lowest in the 1995-2019 survey period.<\/p>\n<p>The outlook for the Delta smelt population remains grim after these lows. Despite good conditions in spring 2018 and 2019, the severely depressed number of adult spawners indicates a continuing weak potential for recovery.<\/p>\n<div id=\"attachment_2710\" style=\"width: 1363px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-2710\" class=\"size-full wp-image-2710\" src=\"http:\/\/calsport.org\/fisheriesblog\/wp-content\/uploads\/2019\/07\/image1.jpeg\" alt=\"\" width=\"1353\" height=\"869\" srcset=\"https:\/\/calsport.org\/fisheriesblog\/wp-content\/uploads\/2019\/07\/image1.jpeg 1353w, https:\/\/calsport.org\/fisheriesblog\/wp-content\/uploads\/2019\/07\/image1-300x193.jpeg 300w, https:\/\/calsport.org\/fisheriesblog\/wp-content\/uploads\/2019\/07\/image1-768x493.jpeg 768w, https:\/\/calsport.org\/fisheriesblog\/wp-content\/uploads\/2019\/07\/image1-1024x658.jpeg 1024w, https:\/\/calsport.org\/fisheriesblog\/wp-content\/uploads\/2019\/07\/image1-467x300.jpeg 467w\" sizes=\"auto, (max-width: 1353px) 100vw, 1353px\" \/><p id=\"caption-attachment-2710\" class=\"wp-caption-text\">Figure 1.
