Summary: Baordwalk nearly done, fixed feet on solar scaffold, moved batteries, controller higher, checked on Stardot camera

Sherman Wetland
2016-07-15

I stopped by about 8am on the way to Tonzi to get a look at the boardwalk and to see how much the solar equipment needed to be raised. The channels are still dry. The boardwalk is nearly finished - itâ€™s still missing some of the railings. There was a bunch of PGE people working on the gas line near the river east of the bridge.

I returned about 1:30pm with some extra scaffolding and cement blocks. I dug out the foot jacks on the west side of the solar scaffolding. I jacked up the scaffolding with the shepherdâ€™s jack and filled the holes with cement blocks. The feet are now resting near the surface on cement. I put cement blocks under the feet on the west side too. I put another boardwalk on the top level of the scaffolding and this was at nearly the same level of the boardwalk and about 6ft above the ground level where the main tower is. I move d the battery box to this level on the northeast corner of the scaffolding near the boardwalk. And I bolted the solar controller box to the corner post of the boardwalk. The power line to the tower can now run along the boardwalk.

I collected the images from the Stardot camera. There were 542 images on the card and they were current. I changed the file names in the Stardot ftp scripts to shorten the names. Campbell seems to think long file names are why image stop being recorded after about 700 images. I collected about 1200 images on a test system in the lab. The file names were westpond_yyyy_mm_dd_hhmmss.jpg and are now SW_mmdd_hhmmss.jpg.

I left two sets of scaffolding frames, two cinder blocks and a fence post chained to the boardwalk railing. The next time out, the lower boardwalk on the solar scaffolding needs to be removed. It could be taken back to Twitchell to use at the rice. There is a fence post leaning against the west side of the scaffolding that could be pounded in and use to anchor the scaffolding. The east side of the scaffolding could be anchored to the boardwalk. We also need to think about raising the data logger box on the main tower.
