I recently started adding this table to presentations about the Delta tunnels. It generated a lot of comments, so I will add it to the blog.
The table above was compiled directly from the BDCP/WaterFix documents over the years. It's clear that the water supply from the tunnels is also on a declining trend, there are more regulations still to come, and there is no protection from future regulations under a Section 7 permit.
In addition, the biological opinions found that endangered and threatened fish species fare worse with the tunnels than under a No Action alternative. Since it is the decline of fish populations that is triggering increased regulations, there isn't a strong reason to believe that additional regulations are less likely with WaterFix than without.
