Success!

After several months of planning, several weeks of construction, several long days of set-up, and lots of hard work and ingenuity by all involved, we finally got the streams running smoothly! It was so exciting to finally see the whole array spinning along, 12 little streams ready to grow biofilms under different treatments and hopefully tell us something about how inputs from large wildlife influence the way the whole river functions.

Leaks!

Again, I can only blame irrational optimism for not thinking we might have some trouble with leaks from streams made out of PVC canvas. Chris and I had done a test on one of the streams, by filling it with water and leaving it outside for a couple of days. When it still held water, we were excited and moved on. But filling 12 streams sitting on bare ground with a precise amount of water was whole different level of testing. 

Building the streams

Setting up our experimental stream array turned out to be no small feat! In some bizarre moment of optimism, I had scheduled one day to get the streams up and running. Impressively, it only took two and half days, which I still consider a win. There were a number of steps along the way, and I don’t think we could have done it without everyone’s contributions and help. 

David in the Mara!

The last few weeks have been some of the busiest, but most fun and successful, of our entire field season. My advisor, Dr. David Post, came in from Yale in mid-January to spend two weeks in the field with us. David visited us in the Mara in 2011, and his insights on the system were invaluable in helping shape our research questions, so we were really excited to have back in the Mara to see what we had accomplished since then.

Yes, that’s our gearbox on the road. Trying to fix a major leak before David Post arrives in a few hours.

Getting closer

We have our first little river prototype made! Ok, it may not look like a little river yet, but just wait until the water is flowing over gravel in the channel!
