Redwood Creek Low-Flow Monitoring

SRF Monitoring team discuss techniques

Updated November 4, 2016

As you can see in our graph below, welcomed rainfall quickly appeared in the watershed and our 2016 low-flow season subsequently culminated on October 22.

Here is a quick 2016 season recap:

The 2016 monitoring season began as one of the wettest years since Bill Eastwood began measuring Redwood Creek flows in 2013. At one of our sites, Bill measured 817 gallons per minute (gpm) on June 24, compared to last year's 140 gpm. Unfortunately, water demands on the Redwood Creek system quickly started drying up the watershed by August. On August 5, the lower end of Miller Creek was already dry.  By September 1, Bill recorded that all but two of our monitoring sites were flowing at less than 1 gallon per minute. That is less than the average kitchen sink (2.5 gpm). When the Redwood Creek and its tributaries cease flowing, the river becomes a network of disconnected pools. There was a slight increase in flows at some of our sites mid-September, possibly due to cooler temperatures. October 12 was the low point for stream flow before the rain started on October 13. On October 12, eight of our twelve monitoring sites were not flowing. After a week of heavy rainfall, all of our sites have water and flowing at an average of 1,200 gallons per minute.


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