This was a study relating to the minimum instream flows needed to sustain endangered salmonid populations in river systems where there are many competing demands for water - hydropower, irrigation, and municipal drinking water being the major needs. In many western rivers, every drop of water is strictly meted out between users with varying claims via a very complex system of water rights. Many rivers are over-appropriated, meaning that there are more rights to remove water than there is water to remove, leaving nothing for fish. A long series of federal court cases, still ongoing, relate to the requirement to leave water in the rivers to support endangered species. All the parties to that litigation have different ideas of how much water fish need to survive. The study, and others like it, seek to set a firm minimum quantity of water that must remain in the river as an "instream flow" to support endangered salmonid populations.

Thank you for the additional information. In this age of "sound bites" this serves to remind us that it's always good to read past the headline. Thank you for educating us all on this important issue.
