Bill Eastwood started monitoring 2017 summer flows throughout Redwood Creek on June 23. Flows have slowly been decreasing since then but are higher througout 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. By the end of July, most flows were higher than the 2016 average (excluding Dinner Creek).

Now into late summer/early fall, streams are seperated into isolated pools as we reach further into the dry season. We saw a dramatic drop in flows in Miller Creek during the first week of August. The water levels in isolated pools are decreasing rapidly and the upstream flow of early August have stopped at the mouth of Miller Creek. Out of the 9 sites we monitor, 3 sites have stopped flowing. As of September 15th, only the lower mainstem Redwood Creek maintains flows over 1 gallon per minute.

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

Hover your mouse over the graph lines to see daily values. Click on the Monitoring Site Labels (Dinner Creek, Miller Creek, etc.) to remove/add information.

Redwood Creek 1, 2, 2.5, 3, & 4 and Upper Redwood Creek are mainstem sites.

Dinner Creek and Miller Creek are Redwood Creek tributaries.
