Lost, found, and looking forward

A lost data logger comes home!

In August 2018, when we were first thinking of WaterWealth taking up stream temperature monitoring, we bought one Onset temperature logger to try out. Impressed with the logger and free phone app they work with, we went ahead, but there was lots to do before we'd be ready to deploy loggers. Meanwhile we thought this one may as well be in the water somewhere.

The last time we saw that first logger was March 17, 2019 when it was put into Hope River in a landscaping brick (for mass and protection) with a rope tied to a log on shore.

Going back a few months later, we couldn't find it! Tried again from time to time, looking from shore, wading, poking around in the canary reed grass, getting menaced by a fierce crayfish. Eventually had to conclude that the logger really was gone.

February 20, 2021 I was just out for a walk and went by the logger location. Grass had died down and the water was low and quite clear for that stream. Was that our brick I could see!?

Went back the next day with waders and was excited to find it was our brick, and the logger still inside! The rope was still attached too, just not to the log. How did that happen?

I rinsed the brick off in the stream, took it home and took the logger out. It looked like it had gone over to the dark side. (Shown here beside a new one.)

It did clean up fairly well with a bit of elbow grease, and with a new battery the logger 'woke up' and seems good as new! Plucky little logger had kept hourly temperature records till it logged low power October 25 and "Safe Shutdown" at 6:31 am October 27. Its little CR2032 battery had lasted 2 years, 2 months and 13 days from when we first bought the logger and powered it on.

The quality, ease of use, and relatively low cost of these data loggers allows them to be deployed and managed by volunteers as a basis of watershed monitoring programs at scales that would have been prohibitively expensive just a few years ago, and that are needed now like never before.

WaterWealth will be listening to the water, networking with diverse allies, and sharing experience with peers to get ahead of these unprecedented environmental conditions. Pushing back against environmental degradation, biodiversity loss, and climate change while learning about and protecting our shared home waters, to help ensure that wild salmon will always share these home waters too.
