Data Logger Redeployed in Hoy Creek

Matt Watts helped with the first deployment in 2022 of the temperature data logger, housed within the cinder block you can see in Hoy Creek. This one went missing through the winter/spring.

In August of 2022, volunteers of the Hoy/Scott Watershed Society went to deploy a temperature logger in Hoy Creek north of the hatchery.

The logger which can be held in the palm of one’s hand was fixed within a cinder block to hold it steady in the stream.

Over the winter/spring however, the block must have been moved along with the movement of heavy water flow and other rocks tumbling down the stream, as when we returned in late spring the logger was nowhere to be found, even though we found the cinder block.

The logger that went missing, seen in Nikki’s hand, connects to the HOBO app.

A deployment report being done on June 7, detailing location, date, water depth, etc, as well as to ensure the logger has been connected to the app. Seen here, Anne Woosnam records while Nikki provides the information.

In June of 2023, we returned again with Nikki Kroetcsh, DFO’s PSEC Community Engagement Coordinator to redeploy another logger, this time fixing it within a case to the cement barrier along the stream.

It's important to capture photos as when we return to check the logger and upload data into an app on our phone, the location can change drastically.

We’re pretty sure this one will stay put!

The Society is maintaining two other locations with loggers. One is south of the hatchery and monitors temperature, and the third one is adjacent to the hatchery which monitors temperature and other details, however, this one is not to be confused with the Flowlink monitoring system.

See our Facebook photo album.

Nikki prepared the casing to house the logger, which will be secured to the concrete wall seen in front of her.

The new casing for the logger can been seen fixed to the concrete beneath the water. Let’s hope it remains there! Photos taken by Robbin Whachell.

Stream Monitoring Data Loggers Deployed at Hoy Creek

On August 9, members of Hoy/Scott Watershed Society met with Nikki Kroetsch, PSEC Community Engagement Coordinator (Ecosystems Science, Fisheries and Oceans Canada) to learn how to download data from a conductivity logger placed in Hoy Creek near the hatchery. This logger has been capturing data for over a year and monitors conductivity, temperature, and water depth. Conductivity is the measure of water's ability to conduct electrical current and is affected by the presence of pollutants and salts.

Finding the GPS location.

Time was also spent re-deploying two temperature data loggers; one upstream (north) and one downstream (south) of the hatchery in Coquitlam. They were redeployed as both initial ones were lost during the last major weather events featuring atmospheric rivers.

Society members will download information from the loggers several times a year.

Detailed pictures were taken of each site and GPS coordinates were recorded.
