There was no observed flow. As I waded into the stream a strong sulfur odor was released from the approximately 12” of benthic sediment. Definitely some anaerobic composition going on in here.

Despite a low rainfall total, the crew proceeded with the sampling event with the intent of using these data as a "wet season baseline". The rain did finally begin to fall lightly at 13:30 and continued through the last of our sites two hours later.
Due to the rainfall delay the crew was unable to visit the last site, Upper Santa Rosa Creek, and still make the 16:00 deadline set by the lab for sample delivery. The crew was able to visit all of the other sites, and the following are observations from this sampling day (if a site has no comments, there was nothing unusual to report).
Sampling Events
The following sites were sampled on this day:
-
-
-
Copeland Creek had standing water but did not appear to be flowing. The water was not colored by runoff. There was an oily sheen on the water surface.
-
-
-
Collected a 300ml lab duplicate sample to be split into two parts in the lab (for precision purposes).
-
-
-
Mill Creek was low and clear. There was some rusty colored flocculent along the edges of Mill Creek and Wallace Creek near the confluence of the two. I have seen it in streams before but not quite sure what it is.
-
-
There was maybe 0.3 cfs which must have been groundwater recharge from the little bit of rain we have had this winter since this stream was dry in October.
