Northwest Hydropower Loses Output, No Longer Exceeding 2016

The Bonneville Power Administration reports declining hydro output over the last 11 days, falling to more than 2 GW below last year.  This is resulting in higher thermal generation and lower exports to California.  This difference is about equal to the excess hydro generation we have been seeing recently in California, so the net effect is about zero right now vs last year's hydro output.  This represents a significant change from early January, when both CAISO and BPA were reporting strong hydro power:
