In previous posts, I described the poor status of longfin smelt in the Bay-Delta estuary. In my last longfin post in April, I recommended a higher prescribed June Delta outflow, but none occurred. June outflow was a bare minimum daily 7000 cfs. As it turns out, it may not have done much good because there were simply too few spawners available this year (Figure 1). The Fall Midwater Trawl Index (Recruits) was at a record low as in 2015. The spawner indices for 2017 and 2018 will be less than 0.6, which is so low that few if any recruits will be produced.
