Downstream of HJ Andrews Experimental
Forest LTER: Blue River reservoir as a reference for management changes
contributed by: Christina Murphy (Christina.Murphy@oregonstate.edu), HJ AndrewsLTER Grad Rep and PhD student at Oregon State University
After more
than 3 years abroad, it was exciting to roll out of a plane and into the HJ Andrews. More than anything, I had missed the dark
evergreen color of the Pacific Northwest forests. I started out working as part of phenology
studies already underway at the site. As
an aquatic ecologist, developing my PhD project has slowly taken me downstream
into the Blue River Reservoir (also known as Blue River Lake).

With PIs Dr.
Sherri Johnson and Dr. Ivan Arismendi, I am studying nutrients and food web
dynamics under extended drawdowns meant to help migratory juvenile salmon move
downstream. The reservoirs currently
under study include Blue River, Fall Creek and Hills Creek. In a climate of changing management
strategies, Blue River Reservoir will serve as a reference system. Its proximity to the HJ Andrews LTER site is proving
to be a huge benefit when coordinating a study.

LTER sites
are characterized by long-term data, and by the curiosity of researchers. The Andrews LTER’s proximity to the Blue
River provides us with historic data which would not otherwise be available. The LTER site also has connections, fostering
interagency cooperation which has made our trips on the reservoir for data
collections possible.

So, while
last summer I spent time in the streams of the Andrews, this summer I spent time
floating around the reservoir. Pulling
up water in Van Dorns, hauling in plankton nets, and peering through a
microscope, it is proving to be a very busy summer. Working in a beautiful area to answer
questions about our local resources and how our management actions change the
world around us. Questions which fit
well with the HJ Andrews.

Wishing
everyone a wonderful and educational fall!

P.S. Thanks to
the folks in the Fisheries & Wildlife Department at Oregon State, the US
Army Corps of Engineers, and the US Forest Service. With respect to Blue River we especially want
to thank the local McKenzie River Ranger District for their help!
