Greetings from TCTU Streamkeepers.
"And all at once, summer collapsed into fall.” – Oscar Wilde
The fall "switch" has been flipped with much cooler temperatures. We will continue to monitor our streams through the end of October or when the temperatures drop below 32 degrees, whichever comes first. The test results below freezing begin to be less reliable.
We recorded stream water temperatures in the 52 (i.e. Hay Creek) to 65 degrees (i.e. South Branch Vermillion) range over the last month.
In addition to monitoring streams, we assembled a small team to take part in the Rush River Bio Study. We will be taking bio/ macroinvertebrate samples in October at six of the sixteen sites on the Rush River. Members of KiapTUWish will do the rest of the sites. Below are some of the early observations for all of you bug enthusiasts...
We are thankful to our TU colleagues from KiapTUWish for inviting us to help with the Rush River Bio Study. Data will be compared to an earlier study done on the Rush in 2004 at many of the exact same locations. A similar bio study is also being conducted on the Kinnickinnic River, so data comparisons will also be made with that stream. Our TCTU Streamkeepers are hopeful that we will be able to use some of the knowledge gained to do some bio studies on our TCTU streams in the future. Thank you to TCTU bio study team members Mark Peerenboom, Mitch Abbett, and John Klesch for your help with this project.
Our “targeted” Streamkeepers are monitoring Belle Creek, Eagle Creek, Hay Creek, Little Cannon, Mall of America Creek, South Branch Vermillion, and Trout Brook. Below are some recent chemical readings on these streams.

“General” Streamkeepers are busy conducting more random and spontaneous monitoring of streams in Minnesota and Wisconsin.
