Thermocline

6 posts in this topic

Can someone explain to me what exactly the thermocline is? It is a term I hear a lot but really don't know exactly what it is. Thanks.

A depth in a body of water where there is a definate temperature difference.Cold water is heavier than warm it sinks, the difference between that cold and the sun warmed surface where they meet is the thermocline.

The thermocline is an area of rapidly changing water temperatures. It has to do with water temperature and the changes in density at given temperatures. Water is most dense at 4 degrees C, or about 40 degrees F; so when water temperatures cooled at the surface reach that temperature in the fall, they sink to the bottom. When lakes stratify in the summer they form a thermocline. Eventually the water mixes as temperatures stabilize from top to bottom and you get a turnover. Minnesota lakes are monomictic, meaning they turn over once. Temperatures are relatively uniform from top to bottom in winter. When spring comes and the water heats up, they stratify, stay suspended until the fall, mix again, and then the lake freezes up.

Right now we're closing in on the fall turnover. Water temperatures range from 55-60. If we get a cold snap and the weather stays windy, we may only be a couple weeks from the fall turnover.

how long does it take for a lake to "turn over". Does it take a day or a week....

A couple days. You can usually tell when it has occurred because the water clarity temporarily diminishes and there is a slight rotten eggs odor as decaying matter mixed in the stagnant hypolimnion (bottom layer) water rises to the top.

    • I have been meaning to try to stick a yote too whenever I was out I hoped one would show up instead of a turkey.
    • should have set up in the grass! Uncle went back for evening set up at a pinch point hen and tom came through to go back to roost but no shot!
    • Beside the fun of fooling a turkey and sticking it witj my bow,this is why I love turkey hunting. Slow smoked with apple on the pellet smoker. 
    • Does anyone have a water driven backup sump pump? They look like the cats meow if you live in town. Or does code even allow them? If they are not allowed what is the best battery backup ones?
    • Got out Saturday morning. Perfect weather. Jakes and hens. Had a new group of 6 hens come in with no tom or jakes.   Did have a yote come out of nowhere right into my dekes. 12 yards. Just as I was drawing on it , it must have scented me and booked. A second yote crossed about 50 yards out. Sticking a yote is on my bucket list.   All in all a great morning.    
    • Good season Wild, onto next year. Should be some changes but I don't expect us to do anything crazy. Need to sign Granlund and Nino and that will use up a lot of our cap space. Can't afford Hanzel and possibly Haula and Vegas will be taking a player off our hands. I'm more interested to see who can sustain or step up their scoring next year or if anyone regresses. Granlund, Coyle, Nino, Zucker, Dumba, Spurgeon and Brodin all had career years, those are good problems to have. They showed us a lot but I think they still have room to grow and that is what we need. We have a nice cast of vets but they are likely too old to lead us to a cup, they would be in more supporting rolls. Hopefully our now seasoned young core and continue to build on their impressive seasons. Always disappointing to lose, even worse when you can't score against your old coach but I like the our team and hopefully we can keep getting better.
    • I'm not the most techy 40yr old out there, so I will try to explain what I'm looking to do and hopefully someone can point me in the direction I need to go. I have a cabin in the Chippawa National Forrest, no phone at the cabin and our cell phones dont work at the cabin either. My teenage son wants to take the wheeler and go riding alone. I worry he's going to get lost or if the wheeler breaks down he can't call my cell for help. When we drive my truck around; the gps in it works all the time.  I know I can put a GPS app on my sons phone so he can track his route in reverse to get back to the cabin. But what if he breaks down?  Does anyone know if there is a gps app that I could "pair" up me and my son's phone so I can see where he is at? kill 2 birds with one stone per say, he can use it to navigate himself on the wheeler and I can see where he's at incase I need to rescue him.  Thanks for the help.
    • Hit the Red River over the weekend for the 2nd time this spring. First outing wasn't great with a handful of smaller cats all under 10lbs. This weekend was a different story as we ended up with 15 cats Friday night. 5 over 10lbs, 2 of which were high teens fish. All caught on cut river bait.  Cats were on the shallow side of the river. Water was high and flowing pretty good. All fish were caught and released. Great night of fishin w no bugs to bother us and very nice weather! Gonna give it another whirl soon in a boat this time. Have a look!!
