The result of this week's efforts. Grey line is water temperature, and blue line is water depth. You can see there was a major rain event on Thursday night and a resulting sudden rise in river depth from about 0.3 metres to 1.5 metres. It was great to be able to check that the installation is solid and was not washed away by all that water. Five days of data doesn't really tell us much. We probably need at least 3 years of data, and better still 5 years of data before we can start to make any kind of meaningful interpretation. Fortunately the logger will just keep taking readings automatically. There is always a risk of vandalism or theft, but the station itself weighs 100 lbs, and is fastened with both a stake and a metal cable, so there would be some work involved for someone to take this thing away. Not entirely out of the question, but not something that someone is just going to do on a whim. But time will tell. At least 5 days out, everything is going well.
