It’s time to head to the upper watershed in search of native trout. It has been another disappointingly dry year, but there is water in the stream, and some chance of spotting native fish. The flow in the upper Arroyo stream is now about 2 cubic feet per second, compared to the historic average of 5-6 cfs for this time of year, but 2 cfs is better than it’s been for a while.
WHERE TO LOOK: The most likely place to find native trout would be in the pools up around Switzer’s Falls and in nearby Bear Canyon, but trout sometimes go as far as the mouth of the Arroyo near Jet Propulsion Laboratory. (Btw, the Mount Wilson Bicycling Association has been doing monthly trail restoration work in the stretch of the Gabrielino Trail between Oakwilde and Switzer’s Camp.)
No one that I know of has claimed to see any native trout since the Station Fire nine years ago. I recently went with Wendy Katagi of Stillwater Sciences to visit the Riverside Corona Resource Conservation District, which has an excellent native fish program. They are willing to help us restore native fish in the Arroyo Seco, but first we need to document their current status, so we need your help now.
Take a hike! It’s always enjoyable in the upper Arroyo, particularly this time of year. Let me know what you find, and thanks for caring!
