"The average frequency and duration of continuous “low flow” (<20 cms) periods during Chinook migration dwindled to zero during the 1960s and 1970s, reflecting the benefits of water storage behind the dam constructed at the outlet of Great Central Lake in the 1950s. However, the frequency of daily low flow (<20 cms) and high flow (>80 cms) occurrences have been increasing since the 1980s, indicating increased variability in flows associated with warmer, drier conditions in the 1990s, followed by cooler, wetter conditions in the 2000s"--Abstract.
