Temperature Monitoring

In 2016, the North Coast Watershed Association began an “Adopt-A-Logger” volunteer temperature monitoring program to observe summertime high temperatures in the Youngs Bay and Skipanon watersheds. In 2017, we are expanding our monitoring network to include sites in the Nicolai-Wikiup and Ecola Creek watersheds as well.

You can explore the map below to find the data collected at each site that we monitored in 2016 (green sites). Temperature is compared to the ODEQ water quality standard for summertime temperature, which is 18°C for summertime rearing and migration of salmonids.


Our new locations for 2017 are in blue. 2017 data will be posted at the end of the calendar year. If you’d like to get involved, read more about our “Adopt-A-Logger” model of monitoring below and contact us!

Our “Adopt-A-Logger” Model of Monitoring

NCWA volunteer collects data from logger

We rely on the help of volunteers to install, check on, and retrieve our temperature data loggers. Citizens (including you) can adopt a data logger to help manage during the summer months. We install loggers in May and retrieve them in September/October. Volunteers who “adopt-a-logger” check on the logger mid-season to make sure it’s still under water collecting data and they assist staff in deploying and retrieving the logger. If you live near a logger site or don’t mind driving to one, contact us to find out how you can “Adopt-a-Logger.”

Why we’re monitoring temperature

Water temperature is a limiting factor for survival of salmon and other cold-water fish. Temperature is also an indicator of the amount of dissolved oxygen in the water – another important parameter affecting the health of all species in the watershed, including us. With continuous, long-term temperature data collection we can assist Oregon Department of Environmental Quality (ODEQ) in establishing Total Maximum Daily Load (TMDL) data, prioritize riparian plantings within our organization, and share this information with the public and other agencies that are working within these watersheds.

No agency currently has multi-year continuous temperature data for the Youngs Bay, Skipanon, or Nicolai-Wikiup watersheds. Oregon Department of Environmental Quality has major data gaps in these watersheds. Without the collection and processing of temperature data within these watersheds, NCWA, DEQ, and other agencies have no way to observe summertime high temperatures, how long they last, and how they vary year to year. Our most basic question is: “do these streams meet the ODEQ water quality standard for summertime temperature?” – which is 18°C for summertime rearing and migration.
