The Mill Creek logger keeps track of temperature. It also tracks the depth of the water. Because even on hot summer days, healthy creek water stays cool, the way trout like it.
And even when it hasn’t rained for a while and creeks are low, cool groundwater keeps the creek flowing and habitable for trout and other creek critters.
The data logger also keeps track of something called “electrical conductivity.” Conductivity measures water’s ability to carry electrical current based on the concentration of ions in the water.
In Pocono streams, most conductivity comes from salt that’s washed off roads and parking lots.
Even salt that filters into the ground eventually reaches streams. In areas near interstates and other busy highways, salt levels are so built up in groundwater that conductivity remains high throughout summer.
Fortunately, the area’s headwater streams, including Mill Creek in the Upper Brodhead watershed, look good. Keeping them that way is the point of the data logger.
Knowing our streams, and keeping track of what’s affecting them, is part of loving where you live.

You can see data loggers throughout the Brodhead Watershed at monitormywatershed.org. Search for “Brodhead” for sites maintained by BWA and “East Stroudsburg” for sites maintained by ESU.

How Clean Is Your Stream?
DEP’s Interactive Report Viewer allows you to zoom in on your own stream or watershed to find out how clean your stream is or if it has impaired water quality using the latest information in the draft 2020 Water Quality Report.
