SRF Monitoring team discuss techniques

Bill Eastwood started monitoring 2017 summer flows throughout Redwood Creek on June 23. Flows have slowly been decreasing since then but are higher throughout the watershed compared to last year. In mid-June 2016, the average flow was 583.5 gpm and mid-June 2017, the average flow was 1,137.6 gpm. During July, most flows were higher than the 2016 average (excluding Dinner Creek).  Miller Creek stopped flowing mid-August, as did some upper mainstem Redwood Creek sites by mid-September. We measured a steady decline in flows for all our monitoring sites throughout August and September. By the end of October, Redwood Creek was separated into isolated pools and out of the 9 sites we monitor, only 3 sites maintained flows over 1 gallon per minute. All of these 3 sites are located in the lower mainstem Redwood Creek. Flows started to return with fall rain in late October. Our 2017 season ended on November 11, a couple of weeks past our 2016 end date.

Data is plotted on a logarithmic scale; 0.01 represents "0" or "No flow." Measurements are rounded to the nearest tenths.
