E. Emile OP. what happens to the fish when the lake turns over? The bottom water can carry sediment and decomposing organic matter, thus creating smelly and dirty looking water. Starting in the spring and over the course of the summer, surface waters absorb a lot of the sun’s energy and can heat extensively, causing them to become quite buoyant. Once you know what to look for you can determine where the thermocline is and if it is starting to dissipate. Just because water temperatures turn cold, lakes turn over and fish disperse, doesn't mean that they won't feed or that they aren't catchable, they are. The deep water contains an abundance of decaying matter and sulfurous gases; when it reaches the surface, it produces a telltale odor that indicates the process has begun. Something strange and wonderful happens when water reaches a temperature of approximately 390 Fahrenheit (40 Celsius). And with that, the most important word to remember from this article is, Oxygen! THe fish will retreat to the deeper part of the pond. I had a request from a reader to do a lake turn over article. Does it shut down the bite and for how long? But there is too much difference in temperature between the surface water and that at depth to allow for complete mixing of all the water in the lake. Posted in Podcast, Pyramid Lake, Reno Fly Shop commentLeave a Comment on EP038: Sudeep Chandra – What LCT and Taimen have in Common and What Happens When a Lake Turns Over Post navigation EP037: Travis Hawks – 2017 State of the Truckee River Decreasing amount of daylight, cooler temperatures, and the drastic color changes to leaves have started, reminding us that fall has arrived. When this happens, fish cannot use this habitat and are squeezed into waters near the surface. Winds and storms can cause some mixing and do add some oxygen; atmospheric oxygen is added by the air-water interaction to the oxygen produced within the water by aquatic plants. If water in the lake never turns over, the surface dwelling organisms will have a reduce food supply. Another way to capitalize on the turnover period is to search out lakes that have not turned yet or have turned and already stabilized. Low light periods, such as early morning, late afternoon, or cloudy days, are the best time to target gamefish in basins, as this is when plankton is most active. As the surface water begins to cool in the fall, it eventually equalizes in temperature with the deeper water. Most wildlife in the basin especially fish spend their entire life cycle in or near the lakes so they are the most affected. One thing to watch is your depth finder. Crankbaits, spinnerbaits, and all other forms of search lures should be used during turnover, allowing an angler to cover water quickly to find these spread out fish. That is why the fishing is a bit easier up the river where there is some current and cooler water. Some have mentioned your site. Toward the end of summer, the deep water becomes quite depleted of oxygen because no mixing has taken place. One that brings a change to the many lakes in our region, The Fall Turnover. How does this affect fishing? And with this great process, comes a time where finding fish can become difficult. They are found on every continent and in every kind of environmentin mountains and deserts, on plains, and near seashores. In most cases it is a gradual breakdown of the thermocline, so if the lake has turned over and the fish don’t seem to be where they were back off and look a bit deeper as the water with oxygen has become more dense as it cools and sunk to the bottom. I was glad to get the request but must admit this something I knew very little about. The turnover is a huge change to the fish’s habitat and opens up a new world of previously oxygen depleted water which makes the fish move. So now, as turnover has come to your favorite lake, and other water depths have become oxygenated, these same fish will not be limited in where they can roam and find prey. Well, it is wonderful for lakes and the life in them, not so for the roads on which we drive -- more on that later. In most cases it is a gradual breakdown of the thermocline, so if the lake has turned over and the fish don’t seem to be where they were back off and look a bit deeper as the water with oxygen has become more dense as it cools … Thanks for your help!".

How to Connect WithOver 276,000 Anglers Joe MartinBigfoot Resort, A satisfied FishingMinnesota member says, This ice on its own isn’t necessarily dangerous. As the days get shorter and cooler, and energy is transported away from/out of the lake, mixing becomes easier. The good news is, post turn over fall fishing patterns begin to start up and great fishing is just around the corner. Most of them want to know more about you. But the highly-oxygenated water from the surface falls to the bottom, thus spreading oxygen throughout the lake. Once you know what to look for you can determine where the thermocline is and if it is starting to dissipate. Because each lake is unique in its own right, some will turn earlier, some later, and some not at all. Because a lake has oxygen throughout the entire water column after turnover, fish can be found anywhere and everywhere. In any case, as water cools to that temperature, it does, as predicted, contract and become more dense, ultimately sinking to the bottom of the lake and … When a lake turns, the surface water falls and the now-warmer water from the bottom rises. A basic rule of thumb to follow is: smaller shallower lakes will turn over first, large deep lakes will turn over last, and the smallest and shallowest lakes may not turn at all because wind constantly keeps the water circulating throughout the year. (Unless you are near the great lakes or Canada) This is called a lake turn over. The fall season, one of the most beautiful seasons in the northern reaches of our country, is starting to show it's tell tale signs. I have referenced R. Karl for some of the scientific information I used. It explains why, in the late fall and winter, fish will often seek out this relatively “warm” stable layer of water at the bottom of the lake. We all know suspended fish on the main lake can be hard to catch. The deep water contains an abundance of decaying matter and sulfurous gases; when it reaches the surface, it produces a telltale odor that indicates the process has begun. However, if your lake or pond completely freezes over, it can reduce the water’s oxygen and introduce toxic gases that could harm your fish population. This will help in finding fish. We're filling the cabins, and also our RV overflow sites. I hope this helps you all catch more fish and understand what is going on during the turn over. I have referenced R. Karl for some of the scientific information I used. This dense, oxygen rich, surface water sinks to the bottom which in turns pushes oxygen depleted water from the bottom to the surface. "Business has been very good. Toward the end of summer, the deep water becomes quite depleted of oxygen because no mixing has taken place. What happens when you throw a mythic goldfish at a vault? Increase fish harvest and decrease aquatic growth with these useful tips! If the turnover happens very quickly it can cause problems, even fish kills, because it can deplete the oxygen in the levels of the lake where the fish currently reside. Understanding what is happening in the lake will improve your fall fishing and help you find the active and hungry fish. Some phytoplankton remain productive throughout the winter by utilizing the little bit of light that makes it through the ice and snow. Because of the density-temperature relationship, many lakes in temperate climates tend to stratify, that is, they separate into distinct layers. At some point, the majority of the water in the lake reaches an approximately uniform temperature. Angel Eyes, Pro Series Jigs, Crappie jigs and plastics, Glow devils and MUCH MORE, Don't miss out - click here. Below-freezing temperatures can cause ice to form over your pond or lake. A run and gun approach as some would put it. Fish that live in a pond are able to survive the winter when the pond freezes because of how they are able to adapt to the drastic changes. How does Turnover Affect My Pond or Lake? The cooler water (with a higher oxygen content) at the surface begins to sink into and through the thermocline, forcing warmer and less dense water to the surface, eventually erasing the temperature stratification built up over the summer.
