Ken Jarrett, a fisheries biologist from Stillwater Sciences, came out on an overcast Sunday to train volunteers how to assess stream habitat for native trout and aquatic species.
The crew picked this reach of the Arroyo stream a couple of miles up into the mountain watershed to evaluate stream conditions.
The flow (about one cubic foot per second) is low for this time of year, about 20% of the historic average, but the conditions are still surprisingly good.

Measuring the run, characterizing the gravel and sand, and taking the stream temperature are all part of the lessons Ken taught the Trout Scouts.
