July Streamkeepers Report

"And once the storm is over, you won't remember how you made it through, how you managed to survive.  But one thing is certain, When you come out of the storm, you won't be the same person who walked in.  That's what this storm's all about." 
Haruki Murakami, Fly Fisherman, Aug-Sept, 2026
​
When reading a recent article in Fly Fisherman, my mind immediately wandered back to a fateful day while trout fishing when I was caught in a terrible storm.  The fishing was very good that day, and I was not paying close attention to the weather.   
I was fishing the Root River on a beautiful summer day in SE Minnesota.  I was preoccupied with a caddis hatch and the brown trout that were actively feeding. 
The next thing I knew, the storm moved in quickly.  Threatening clouds moved in.  The winds kicked up.   Gusts exceeded 50 mph.  The torrential rain began.  I felt completely helpless as I struggled to remain standing.  I was leaning into the wind at about a 45 degree angle and finally ended up on the ground.  By the time it was over, I was exhausted and totally soaked from the waist up.  Luckily, I had my waders on and did not get hit by any flying debris or lightning!  The storm came abruptly, and just as quickly, it was gone. 
The peonies and other flowers from a neighboring farm were destroyed and scattered all over the road.  Branches from nearby trees were strewn over the roadway.  My immediate thought was, "Holy CRA_!  I didn't see that coming."   
 
Have you ever had this kind of experience? 
 
The lesson was clear.  Be careful, especially during this stormy time of the year where we have some of the warmest summer days.  And be sure to check river conditions and water temperatures following a major rain event.  If the water temperatures are above 68 degrees, "give trout a break" by either coming back on another day or finding colder water.
 
Time to listen to "Riders on the Storm" by The Doors.  I dread being caught in the storm but really enjoy the rumbling sounds and majesty of a good storm.  Good luck as you face storms on area streams, rivers, and beyond.

NITRATE POLLUTION AWARENESS WEEK IS COMING  Source:  Sam Puckett, Clean Water Program Director, Izaak Walton League
 
July is here, and that means Nitrate Pollution Awareness Week is right around the corner!  Nitrate is an invisible, tasteless contaminant with serious impacts on human health and environmental quality. In streams and lakes, nitrate pollution causes an ecological imbalance that is responsible for producing algae blooms and areas devoid of oxygen, called dead zones. In our drinking water, elevated nitrate contributes to increased incidence of thyroid disease, pre-term births, neural tube birth defects and cancers. Despite these harmful impacts, nitrate from sources like fertilizers, manure, and sewage continues to be added to the landscape, polluting waterways and threatening communities nationwide.
That’s why the TCTU Streamkeepers supports our partner organization, the Izaak Walton League of America, as they spearhead Nitrate Pollution Awareness Week, from July 26- August 1, 2026, to raise awareness about the sources and impacts of nitrate pollution and to connect members of the public with opportunities to monitor nitrate pollution and advocate for solutions.
Read on to learn more about what Nitrate Pollution Awareness Week will entail and how to get involved by clicking the embedded links above!  You can join by learning, monitoring, and/or becoming an advocate for cleaner water.  We encourage you to participate in Nitrate Pollution Awareness Week, and there are even chances to win valuable prizes!  Help us as we strive to get the nitrates out of our streams and rivers.
That's all for now.  Tight lines.

STREAM READINGS 2026
TCTU Streamkeeper monitor volunteers have been busy.  We have recorded 78 readings so far this year and 25 more readings over the last month.
 
Our coldest water temperature of the year so far was recorded at Brown's Creek on April 21st and came it in at 5.9 degrees Celsius and 43 degrees Fahrenheit.  The warmest water temperature reading so far this year was at Little Cannon at a whopping 23.5 degrees Celsius on June 30th and a balmy 74.3 degrees Fahrenheit.  There have already been a few readings on our area streams where we need to "give trout a break."
