For the first time in 20 years, it's possible that the 1,400 irrigators who have farmed for generations on 225,000 acres (91,000 hectares) of reclaimed farmland will get no water at all — or so little that farming wouldn't be worth it. Several tribes in Oregon and California are equally desperate for water to sustain threatened and endangered species of fish central to their heritage.

A network of six wildlife refuges that make up the largest wetland complex west of the Mississippi River also depend on the project's water, but will likely go dry this year.
